FREE 3 Meter trimaran sailboat

posted Sep 14, 2020, 6:08 PM by Mark Olsoe   [ updated Mar 30, 2021, 8:44 PM ]

A Marples Searunner Constant Camber 3M trimaran is available for FREE.  The boat is located in the Illahee area of Bremerton.

Please call or text Eric Kuhner at 206-371-2135 to view.

My father, Ben Kuhner, built this boat about 20 or so years ago, but it has not been sailed in more than a decade. It has been tarped and is complete except for the mast. It is in good condition, but will need attention to all rigging, etc plus construction of a new mast. The mast requires the purchase of a simple aluminum tube plus the addition of some simple hardware as specified by Marple's plans which are available from a local owner of another of these 3 meter class boats.  There are several other owners of these 3 meter sailboats in the area so there is the possibility of class racing as was very popular a number of years ago. There is a trailer and a wheeled cart to enable one person to move these boats—my dad was able to carry one in the bed of his pickup and one on a trailer behind to tow for meet-ups and races. The condition of the trailer and cart is ok but tires are tbd but likely poor.

This would make a great project for someone who would like to learn to sail in a very immediate and fun way, and to potentially race or as a parent/child project.

As I’m sure many of you know, John Marples designed the Constant Camber 3-meter sailboat as a racing class for solo sailors.  More info here: CC 3M Trimaran

Airdock Boat Lift - $2000 (Seattle)

posted Oct 28, 2018, 4:36 PM by PacificNorthWest MultihullAssoc   [ updated Oct 29, 2018, 4:26 PM by William Quigley ]

The Airdock boat lift uses four inflatable bags to lift a boat out of the water. Unlike other boat lifts, the Airdock has no permanent attachment to the seabed or to the dock, so it's permissible in marinas that do not allow boat lifts. It can lift a boat up to 34 feet long and 10,000 pounds. I've been using this Airdock for 6 years and it's in great working condition. I recently replaced the blowers on the air pump. Located at Shilshole Bay Marina. Great for multihulls and power boats. Saves thousands of dollars in haulouts and antifouling paint, which may be illegal in a few years.
Includes 4 air bags, PVC frame (approx 28' x 10', dismantles for trailering), hoses, blower, extra (new in box) size "D" bag, and patch/repair kit.
Originally cost over $6000, not including spare air bag. Email

For Sale: 80-90% complete Wharram Raka 36' project

posted Jan 31, 2018, 9:53 PM by PacificNorthWest MultihullAssoc

Approximately 500-1000 hours work remaining to full completion (approximately 3,000 hours into the build already).  Built by an aircraft mechanic who had previously built a Cross trimaran - so an experienced builder.  Asking price includes all tools and materials (table saw, planers, hand tools, power tools).  Asking price also includes mast/boom, schottenheimer sails, near new Yamaha high thrust 9.9 long-shaft outboard, running rigging, and standing rigging.  There isn't much to be purchased to get this sprightly cat to completion.  The Raka is the performance catamaran of the Wharram designs.  It would make an excellent R2AK boat!  For the right buyer it is possible that it could be completed at the Seller's home where it is out of the weather under a quonset shelter in the Gig Harbor area.  She is demountable for loading and launching.  Asking $35k obo.  Contact Matthew Dunning 206-297-1151 or email
