F-22 Technical And Development Details

Random Details covering the F-22's Earlier Development - Latest Photos at Top, First Launching at Bottom

Latest interior photo, with centrboard

Hull #11 being resin infused

The worlds best shipping cradle? Will be used to ship #8 and can be later used as a yard trolley, or
it can be fitted on a suitable trailer frame

We have also been working with Southern Spars to develop a premium carbon mast for the F-22R, and the
first two test masts have now been made. Still a little work to do yet, but these quality masts should become
optional for the F-22R later this year.

Assembled at Southern Spars

No. 7 Pre-Delivery Water test

No. 7 on the trailer at the launching ramp. This boat is being shipped to Dubai for Robert Lakos.

On the water and preparing to raise the mast

Mast up and ready to go

Under sail, but jib only this time. We found a bolt rope problem with the mainsail that prevented it
going up. Easily rectified, but not on the boat.

However, it performed very well under jib only, tacking easily.

Now back at the dock, and soon to be disassembled and packed into the container for shipping. Up until
now it has been our policy to test launch and sail every boat, but this will soon end, as sails are now
fully sorted out (bolt rope issue found and solved). Future boats will still be test launched to check
foils, folding, and for leaks, but sailing adds several hours, and will no longer be done as a matter of
routine, unless specifically requested. This is how it was for every F-27 after around boat #7, and our
priority now is to speed deliveries up.

Production decals are now also finalized, plus every NZ built boat comes with my signature inside

Feedback from new owner of #1:

Paul Steinhardt has purchased BOOM, the original factory boat, and having previously owned an F-25, Sprint, and F-9A it was interesting
to hear his opinion. Paul writes:

Hi Ian,

Thanks for the note, and we have really been enjoying the new boat. I am amazed at how it performs for it's size. It would seem to me
that it is very close performance wise in a number of conditions to the F-9. It also has a big boat feel when compared to the F-25 and the
Sprint.

Boat hardly moves when you jump on board and forward buoyancy is excellent compared to say the Sprint. Helm is really light and the
sheet loads compared to the F-9 are easy for us older guys!! I was always worried about how wet the boat might be but to my delight
this is not the case.

Raising / lowering the rig is a treat compared to the F-9. All up I am really impressed with the capability, performance and build quality.
This is my 4th boat of your designs and it is a quantum leap. Seems like you have really got it nailed with this design.

We have had pretty good results in some of the racing that we have done. We have fitted a much stiffer top batten to the old main which
has made a big improvement. Also much easier to furl the main on the batten as opposed to rolling it on it's own.

Keep up the good work.

Regards.

Paul Steinhardt

Another Test Launching

Arriving at the ramp

Side Guide Post in its trailering position

Now raised - this post is used on the leeward side when there are high cross winds at the ramp, and
it will keep the boat centered on the trailer.

Launched and alongside a popular 22' monohull trailer sailer - one can see the huge difference.

Mast quickly went up and all is now ready for the test sail where everything went perfectly.
This is the first F-22 with the kickup centerboard, which also performed exactly as expected.

Back at the dock a short while later with mast lowered. The 'plug in' seatbacks were very comfortable
and worked extremely well.

First Swiss F-22 Sailing

Markus Stacher's F-22 #5 is now sailing in Switzerland, and Markus is very happy

On the lake with young Jan Stacher getting the best view.

 

July 18th, 2015

Finished cockpit seatbacks now in position, making this easily the most comfortable cockpit I have ever
sat in. When not in use they simply unplug and store under the cockpit seats

Centerboard control lines can be seen at right

Close up of centerboard control lines. I have used centerboards for years, and they are a great asset in
shallow water due to their ability to kick back and up should they hit bottom. Centerboards can be tricky
to design so that they work well, and the F-22 is the best yet. Only down side of centerboards has been
a tendency for water to leak out of the control line holes at speed, while sometimes even a geyser of water
can shoot up. However, a new baffle system inside the case should prevent this with the F-22, plus the
lines are a close fit in the exit holes in the cover plate due to plastic bushings. A clam cleat is used to hold
board down, as these only have limited strength and will let board kick back before the boat is damaged.
If needed, they can also be further weakened by filing the teeth a little. Red line is up, blue line is down.

The other big advantage of a centerboard is a roomier and much more open interior.

The photos above are a bit factory/work related, but we do have a more interesting one just in from Neville McElroy below, showing
his F-22 Gumphy finishing just one second behind a Twiggy during a race on Pittwater (Sydney) last weekend:

Twiggy is a famous Crowther racing design, so it was a good effort by Gumphy. Gumphy has now been sold
is now in Switzerland.

F-22 Heading To Europe

Marcus Stacher's F-22 is now on its way to Switzerland:

Starting to load into the container

Now all the way in

Floats and beams now in place

and finally - the mast

Truck ready to pick up - these side loading trucks (NZ invention) are fantastic and make everything easy.

Lifting the container on

...and on its way. Next boat is heading to the USA (and hopefully sometime in June). Still getting
some kinks out of the production process, but finally starting to speed up

 

Outboard mount now consists of a simple molded mounting pod that is glued and bolted onto the main hull side,
to which an pivoting bracket is then bolted. The stern continues to be kept clean and uncluttered, while the
side mount allows outboard to be kept further forward with the prop in a much better position. The adjustable
bracket then adds the option of variable height, which means every condition can be covered. The above
photo shows bracket at mid position which still gives plenty of prop depth, even on our freshly launched
factory boat, which has yet to be fitted out, so it was ultra light. The transom is floating 150mm (6")
clear of the water!

But one stills need more depth for the biggest chop, which is no problem, as motor can be lowered
another 100mm (4"). Now that is a deep set prop, and will make the F-22 very good at motoring into
a large chop whenever needed.

Motor is still completely accessible and turnable either way, in the shallow or truly deep set position

Tilt on the standard bracket height will be high enough for all except heavily loaded boats

Bracket has now been changed to a stainless steel type

This photo shows just how light this boat was, with transom way above the water, yet the outboard is still
plenty deep enough

Centerboard Details

The first centerboard version, with centerboard now in place.

Shape below hull is exactly the same as the daggerboard version, but slot is longer. Hence there
will be a little more drag, but the more roomy feel inside is significant. Board can also kick back
should bottom be touched, and this is a nice safety feature in shallow waters

Centerboard retracted - it is designed to protrude slightly from slot as shown, when on water, to
fill slot and minimize drag. Will still retract fully in for when on trailer.

The production F-22 is taking time to develop, but many of the original plan built F-22s are
already sailing in numerous areas around the world - this is Thierry Hemard's F-22 sailing in France

Meanwhile, the production F-22 interior is nearing completion, and the above photo shows the now
connected galley sink in its storage position. It also works here, with tap and drain being fully functional,
while the full cabin settee also remains usable.

And just 10 seconds later, it can be in its 'normal use' position, with tap and drain fully operational.
Sink drains overboard and there is no need to connect or disconnect anything for it to be moved.

New cushions just fitted for the first time

Port side aft, stove being stored behind cushion back

Port seatback removed to show the stove storage area.

Stove ready for use, but it is a bit close to cabin side and roof. A heat shield (may be an option) will
take care of this, but stove can also be moved out away from side as shown below.

Stove fully deployed ready for use.

While we are working hard at the factory, Peter Hackett continues working hard in his office on refining all the
cruising aspects. F-22 #1 BOOM! is shown anchored at Moreton Island - nice one Peter!

F-22 'BOOM!' Wins QCYC Winter Series Overall

Peter Hackett's BOOM! did very well in its first Race series, winning the QCYC Winter Series in
Brisbane overall, and Peter writes:

Had a great weekend of sailing. It was again light and the windward leewards really suited our boat and style of
sailing so we started the day on a great note with another line honours and then a third and second over the line I
think, with the overall PCF win for the series. Luckily I was able to drop the big points day with the blown mast.
Awesome series result for a great crew including both daughters, a cousin, and some mates who had to share
the new boat's delights with me. We collected a truckload of data during the series, and have many little jobs
now to get the racing kit really sorted before OMR measurement. The internal fitout continues with some
serious cruising coming up as well.

One of the other competitors - BOSS RACING - a serious racing cat with few creature comforts

F-22 Now Sailing In Australia

(And Wins Its First Race)

Peter Hackett's F-22 BOOM! now sailing in Moreton Bay, Brisbane.

Still some tuning to go, but starting to get it right

and good enough to enter it's first race on Sunday June 1st. Peter writes:

Great day overall on the water although 3-5 knots is not a full spectrum. Port tack favoured start and we got a blinder.
Big monos included an Inglis 11.6 Dream, with a 10 minutes start ahead of us, and we caught and passed all of them.

In our fleet, Boss Racing, a stripped out 11.4 meter cat, Turning Point, the Grainger hulls only rocket, and Frequent Flyer,
a big rig Prescott Firefly were not far behind us at Fisheries beacon after a short windward. Midnight Rain, a plan built
F-22 I tuned up (silly me) got a good shift and went around Fisheries first, and then us. A great day for the F-22 brigade.
The tight kite leg to Otter Rock was not working so unfurled the screacher, peeled the kite down,  and you could shut the
door from then on. That is one powerful combination of sails in light winds and we sailed under the lee of everything,
getting to Otter ahead of fleet easily. Gybed around Otter Rock and left screacher up all the way to finish line 20 minutes
ahead of Boss Racing, then the other cats and monos. We won line honours, and also on handicap,

A happy Peter at the finish line - you can just see the rest of the fleet in the distance.

However, light winds can be a lottery, plus the F-22 is only a small roomy cruiser, and never designed to be a line honors
machine, so, while a 'double is nice first time up, the F-22 is really more a middle of the pack boat. Or maybe we can soon
say the F-22R at least belongs in the top half of the pack.

First F-22 Arrives In Australia!

February 22nd

Rigging Up

More photos were needed to finalize the F-22 Specification and Price Lists (coming soon), and the boat was rigged and launched yesterday for this purpose. Some good photos were obtained of the 'on the water' rigging process and retrieving onto trailer as follows:

Just after arrival, untied and ready to launch

Unfolded and at the dock, just a few minutes later.

Rolling the mast back - spreaders just roll straight over the aft mast support rollers

Attaching mast to carbon step - it just slots on

Fitting mast raising pole

.....and ready to raise

Starting to lift, and there is always some effort required at this stage for mast to initially lift off the aft
support. A good tip is to put some tension on the line, and then give the mast a little heave up and it
will usually just jump off the support. From there on it is easy.

\

Half way up - getting easy now

...and almost there. Mast ball socket automatically aligns with step ball.

The onboard mast raising block.

All done

Want to see how fast the mast can come down?

Mast Lowering Video

Mast lowered, and boat folded again ready for trailer

Just about on - the well carpeted fiberglass bed makes it just about impossible to damage the boat
while retrieving. This is in fact the first time ever that I have not scratched the main hull bow by
now, on some part of the trailer.

almost there

and winching the last bit.

All done, just a wash down, and ready for the road. I'm starting to like this 'rigging on the water'.

February 12th, 2014

Final Setup Sail

February 11th was our first truly glitch free sail, with only a few minor improvements left to do, while we
also tested mast raising on the water. This is an important option, as while the wing mast is relatively small,
there is definitely more windage when at the ramp during strong winds, especially with the taller R mast. The
F-22R is thus a little harder to hold than I like, and this was an aspect that needed to be improved, particularly
when using our local ramp. This is rather exposed with frequent strong winds, plus the basic facilities are just
not very user friendly. The shorter F-22 mast should be fine however.

Handling at the ramp with mast up in strong winds was also now the only remaining thing that would not
be easy to do single handed on the F-22R, and the simple solution is to just have the mast down when at
the ramp. Thus it was decided to set up 'on the water' raising and lowering as a standard feature. This has
been done before as an option, and many prefer it that way, but it was never fully developed other than
as a method to get under a low bridge. Thus a dedicated bow block was setup along with a raising line
that goes back to a winch.

The raising block can be seen, attached to the bow web on each side using a Dyneema line with spliced
loops at each forward end. Very simple and quick to setup, and having the block further aft (as shown)
means the raising line does not rub on the deck. Mast is then easy to winch up or lower using a cabin
top winch, and, based on our first try, it looks like this system will be as fast or even faster than doing
it all on the trailer. One just arrives at the ramp, unties the boat (5 minutes), launches, and then motors
away, raising the mast as one goes. The mast is well stabilized by the raising wires, so there is no
drama even in a small chop, and it will be easy to do single handed.

The Next Two Boats Assembled

Factory view as of today. Boats #2 and #3 are now full assembled with floats, while the trailer for #2
is nearing completion. Prototype (#1 on trailer at left) is undergoing some improvements in the wing
net area and is about to have its wheels changed as part of the development process. The new wheels
and tires will lower the trailering height by another 25mm (1") plus have a much higher load carrying
capacity to more than cover any overloaded boats.  

The new trailer bed is gray, as I initially did not like the first white trailer bed, but now I think I prefer the
white. Decisions, decisions..... Tires on this are of a higher profile, which should suit Australian roads
better (where this trailer is going) and journeys are likely to be very long. Both tire options will be
available in the final price list (which is being redone now).

This is the top of the line trailer version, with stainless steel override disk brakes, polished alloy wheels,
alloy winch (still to be fitted) and alloy jockey wheel.

Meanwhile, at the factory, things have been fairly slow and still a little frustrating, with the last few
aspects being resolved and finalized, which can sometimes take some time. One of these was the
pop-top but this has now turned out to be one of the best setups yet, with the above photo showing
it in the down/closed position

It is a combination sliding and lifting hatch, the above photo showing it slid forward with aft end lifted
slightly (this height is adjustable), giving easy access to cabin, even when mast is down and just above.

Aft end can next be lifted up to full height, to fully open up cabin area (still bare and unfinished).

The side view

Forward end is now lifted up to give standing headroom (1.88m or 6' 2") at the aft end of cabin. This
height can be increased if more headroom is needed, and pop-top can also be made weatherproof when
up by using the optional pop-top cover. Interior is still to be completed, and currently waiting on the
side settees to be made. However, the molds for these have just been finished, so not long now.

Side view fully up. This is easily the most solid and easy to operate pop-top ever to be on an
F-boat.

Meanwhile, while out on the water we have now found that it is possible to roller furl the boomless
main, after it has been reefed. This eliminates annoying sail ties, and tidies the whole thing
up very nicely.

November 9th, 2013

Another Sail With More Photos

Setting up, with a number of new developments in place, including a quicker to setup mast raising
system (30 seconds versus 3 minutes), plus pulpit is now fitted.

Launched again - the fiberglass and aluminum trailer is proving to be a dream to work off.

Unfolded and ready to go, boomless main neatly roller furled. This is getting better and better.

The new pulpit (no bolts) - is set wide and open at front to allow furled screacher to drop inside to where
it can be securely held. It also gives a much wider working area forward (feels very safe), with more
room for the jib to set properly. A fore and aft cross bar may become optional at quarter height, which
means the lower area can also be netted in if wished. Sides are quickly removable by pulling a couple
of pins, so racers can reduce windage and weight if desired.

September 14th, 2013

OUR SECOND SAIL (in much better weather):

Ready to launch, main already on and ready to go from its furled state.

Now launched and at the ramp

Stern view - note how high it is floating

Unfolded - takes about a minute.

Cockpit view with boomless traveler angled forward just the right amount. The tiller is an alloy tube with
a 'soft touch' neoprene sleeve on the end. Tiller slides into a short carbon tiller (white) and can just pull
out, leaving the carbon tiller still usable behind traveler. This gives up to 60° turn per side when motoring
in confined areas, which is considerably more than required. Similarly, more than enough lock with the
full tiller when sailing.

View forward from cockpit - the removal of the permanent coamings have really opened this up, making
it easy to get to wing nets and cross from side to side. The optional 'plug in' backrests (coming) will then
give full height back rests that actually work well (comfortable), but only when needed.

Designer at helm - the first hour was a glassy calm, but boat still kept moving, doing up to 2 knots
in these conditions, when everyone else was motoring. Good helm control was always there, with
the boat never stalling out.

Starting to get a little wind, and mast step area looking forward is shown. Note how all lines come from
mast step area, leaving cabin roof clean and uncluttered. Jib furler lines can still be seen but these will
soon be moved outboard and out of sight along hull.

Lyttelton Heads in sight and we just made it there before having to turn back. No sailing shots
away from the boat yet, as we are still in a checking and testing mode, so no time for posing.

Main being roller furled. It is then just a matter of pulling a pin on the front handle to release the neatly
rolled main (light with no boom) whereupon it is easily stowed below. No awkward main all over the
deck, no need to fold it, and no lazy jacks to mess with.

The finished trailer with the just fitted composite winch post waiting for the boat to return. Very user
friendly with wide non-skid walking areas forward and storage under the winch

Approaching the trailer

Almost on - it will be hard to sustain damage here, as is common, the trailer being so boat and user friendly.

Just a few minor improvements or refinements now left to do, but our priority has now become to get the
next two boats delivered. Thus everyone will be concentrating on these for the next few weeks, while I
also have a trade show to attend. So good sailing photos will have to wait until October whereupon normal
service will resume.....

September 7th, 2013

THE FIRST LAUNCHING!

With the weather now more suitable, it was time for the second try at launching, mast being raised. Probably
the tenth time we have raised the mast now, so it is becoming very routine and trouble free, and easy to
do single-handed

The F-22R SILVER FOX is finally in the water, and floating very high. The well padded fiberglass
trailer bed can be seen, and it is going to be very hard to damage boat on this, with no metal parts to hit.
Note also how high the tilted outboard is above the water. Being too low to where prop can drag on
wave tops has been a common problem.

Now at the dock. After over 12 years of thinking about it, 6 years in development, the all new
production F-22 is finally launched and ready to go.

View from the other side - note the neatly roller furled boomless main ready to go. No bow pole as yet
(composite mount/pole end mold still being made) but it should be ready next week.

Now sailing, where it handled beautifully, with everything working as expected. The bay ahead is Purau
where my original 30 foot tri was moored way back in 1970, before I sailed it to Auckland. So almost
a home coming.

Main hull bow out of the water as is a common characteristic with all F-boats. Not much wind but
we were easily able to average around 5 or 6 knots, with a few 8 knot bursts.

The very clean wake. Helm was very light, and response was excellent.

Mainsail and the rotating carbon wingmast worked very well.

The molded wingnet rail creates an excellent and secure seating area along the float, with ample hand
holds due to the cutouts along the edge. Far more secure than an aluminum extrusion on the deck

The view aft with Farrier Marine staff John McCormack, Arthur Inns, and Craig Johnston enjoying
their first sail - our late winter weather was a little cold, but there were big smiles all round. The absence
of cockpit coamings really made access forward or out to the wingnets very easy, with nothing to step or
trip over. I was not sure how this would work out but I am now a convert. Add on coamings or 'plug in'
seatbacks will however be an option for those who still prefer them.

Back at the dock and folded up ready for the trailer. Folded perfectly as usual, but unlike earlier designs
the side stays will now securely hold the mast up even when folded, and during folding. There is no need
to fit any mast raising wires until one is on the trailer and ready to lower mast. Nothing to forget in other
words. If anything, the stays were a little tight while folded but this will be adjusted on the next boat.

Coming back onto the trailer, with synthetic bow loop about to be connected (no stainless fittings in the
bow). This worked better than expected, and eliminates more troublesome metalwork. Winch post is still
a temporary aluminum one, but this will be replaced by an all composite bow nose piece next week. This
will provide a very safe carpeted landing area for the boat, not to mention a walking area while waiting
for it. It also means we can get rid of the double rollers visible - the metal frame around these being the
only items left that could possibly damage the boat. Ramp was very shallow, but retrieving was still easy.

De-rigging complete and the final wash down. Not many photos yet, and none from 'off the boat' while
sailing. But this first launching was all business, in order to check out all the systems and that everything
worked as it should. Photos were thus a lower priority, but there will be more next time.

Overall a great first sail, and very encouraging, and only a couple of minor problems to rectify.
