The F-82 TRIMARAN

David Wilson's F-82R in Australia

The F-82 superseded the original F-25A trailerable yacht for home builders, and comes in two versions:

F-82A a lower powered version for cruisers and can be built with either wood or foam strip planking

F-82R - a higher powered version for racers, and the direct equivalent to the F-25C - one of the fastest multihulls of its size in the world. The F-82R must be built in foam, for the lightest possible weight.

Both design versions offer excellent all round performance for those who want a fast cruising multihull with a cruiser friendly roomy interior.

The F-82's cockpit will seat six, and is large enough for outdoor sleeping on summer nights. Further aft is a large swim step platform area which allows easy on and off access.

Interior is very roomy, with more headroom and a longer cabin compared to original F-25A. Different interior layouts are possible, with an optional enclosed head, while galley can be at either fwd. or aft end of cabin to suit sleeping requirements. An aft cabin option is now also available.

Both cabin settees are wide and can form two very comfortable permanent quarter berths. Forward is a large double berth, with a huge storage area underneath.

There is standing headroom under the large and unique combination pop-top. This can slide forward for quick cabin access, have the aft end only lifted to act as a dodger, or lift completely up to considerably increase comfort and room below. Sides can be fully enclosed/screened.

Mast is an aluminum or carbon fiber rotating wing section, and mainsail can be boomed or boomless. A retractable 'free standing' bow pole (no side stays required) is used for the asymmetric spinnaker, for convenience and easy handling.

Daggerboard or centerboard are optional, as are a kick-up spade rudder or a transom mounted rudder. An outboard of 4 to 8 HP is recommended and this is mounted on the stern.

Construction can be strip planked foam, cedar or Durakore™

Below is Dean Snow's F-82R 'Redshift" which took line honors in the 1998 Williamstown (Melbourne) to Geelong race in Australia, as part of the "Scotchman's Hill Festival of Sail" (Australia's largest keelboat regatta). 'Redshift' led home a fleet of around 200 boats in 5 hours and 14 minutes, 30 minutes ahead of the Grainger 42' racing trimaran 'Spirit of Emu'.

Dean Snow's "Redshift"

'Redshift' then went on to easily take line honors in the 1998 Marlay Point Race, Australia's largest race for trailer yachts (can be up to 600 boats). Second over the line was Greg Kay's F-28R (seen behind 'Redshift'), which was 1st overall on corrected time. Third over the line was an F-24 Mk II, fourth an F-25A, with another F-25A fifth.

'Redshift' took around 1500 hours to build, and material cost was approximately A$38,000 (US$24,000). 'Redshift' was sold for over A$80,000, and Dean has since built an F-9R.

The F-25C Widespread Panic - F-82R and F-25C are virtually identical,
but the F-82R does have some minor detail improvements

Lyman White's F-25C in Florida

Two different F-82 interiors with centerboards. Cross panel can be fitted between settees (as shown
below) to convert into a huge double with insertion of extra cushions (can be seatbacks)
