All carbon trimaran designed for the performance enthusiast 
with room to cruise

The Warren32 could be classified as an all-out racer with the ability to comfortably 
day sail six and cruise two. The cockpit is aft and seats four comfortably. 
The construction is all carbon fiber over Core-Cell, vacuum bagged.
 


In designing a very light weight multihull, there are two major areas of opportunity to save weight: 

  1. Carbon and Core-Cell works for minimizing weight in the scantlings (hull lay-up) on a square foot basis.  

  2. Using simple, but pleasing, surfaces for the hull shapes works for minimizing hull surface area for a given length. 

 

The spar is a rotating carbon wingmast with an 8” chord and 47 foot length.  LOA is 33 feet with the sugar scoop at the transom adding 12”.  The amas displace 6600 lbs submerged, or 300+% of typical racing displacement.  The working sail area is 688 sq feet, with additional extra headsails available.  The bare boat weighs less than 1500 lbs. With crew, working sails and gear she has a Bruce Number of greater than 2.0. 

Designing a low weight trimaran creates some challenges.  To generate enough righting moment to support the sailplan requires the tri to be wide, and she is almost square at 30 feet BOA.  For this reason and to save weight a folding mechanism was ruled out of the design.


She demounts onto a street-legal 8-foot trailer. A pair of pins at the interface secures the four half-beams. The beams weigh 50 lb. each and are easily lifted by one person.  Each ama weighs 130 lb  and can be carried by two people. Approximate time to assemble is two hours.

The cabin has a reasonably sized Vee birth forward, two seats to starboard which convert to single berths, a galley and table to port. A sliding portable head fits under the Vee birth, or a carbon fiber bucket is available. A navstation to port and some storage rounds out the cabin. Headroom is 5’ 8”. The cabin is entirely open from companionway to bow bulkhead, a distance of 20 feet plus. The daggerboard trunk is to starboard, offset by 8” to allow easy passage by the crew.

How does she sail?

The quickest answer is delightfully. Despite an extreme power to weight ratio she is easy to sail and well mannered. She’ll tack every time without backing the jib and even on the mainsail alone. The ride is smooth in a chop. The fine shape of the hulls forward allows easy entry and dampening is excellent with the flat sterns and large amount of reserve displacement at the bows She is extremely close-winded, tacking through 80 degrees, although 90 degrees will produce the best VMG. 
The acceleration when footing-off is breathtaking. 


 

 


The Warren32 trimaran is available as a finished or bare boat.
The bare boat has an empty cabin, no sails, electronics or an electrical system.



There is a 36 foot version of this boat that has been redesigned for extended cruising. i.e., more head room and cabin space.
