18' Trimaran built for camping. Cutter rigged.

[markstrimaran]

Almost a fully equipped galley. I generally pack about 300 pounds of non essential gear.

The inside will stay dry unless motoring into the wind. It uses 3m Velcro, and buckled straps.

 

[markstrimaran]

Trolling with the main stay sail reefed at 6 feet.
Two fishing poles out the back, and two set on the amas.

My camera lost power on the full sailing video clip.

 

[markstrimaran]

Had a blow out on the dagger board cassette.

Nice to know, that it will still sail with one ama, full of water.

 

[markstrimaran]

Useing the mast as a crane to load camper shell.

 

[markstrimaran]

Season is about over, probably one more sail.
I patched the dagger board cassette using the easiest method possible, the band aid patch.
I will probably store it up side down this winter, as to repaint the bottom.
The trailer was built around a 1200 pound idea, the fully loaded reality is pushing 1600 pounds. 1.5" x 3" 11 gauge trailer stringers are going to stress crack, some time. Faster if I go on any long trips. It is also a built under the boat, prototype, crude but functional.
I have some 1/4" 7" × 2" U beams to build a better trailer with. So it will keep me busy this winter, without any dagger boards to frett with.

Found a well priced, tandem axle boat trailer. Now to fit it.

 

[markstrimaran]

The 2"x4" beams on the trailer, are welded closed, it is built with gauge steel, so it is a mattr of how much rust has thinned the rails.

 

[markstrimaran]

Axle mounts were only held with 2 u bolts.

 

[markstrimaran]

First sail, pictures from early years.

 

[markstrimaran]

Using the axles as saw horses, It is pretty light, 14 gauge steel.
I used backing plates, were I welded the tubes that will support the ama crossmembers.

Cut off the back 36" still need some 2" flat bar to reinforce the cross beams, that are rusted through, along the center bend.

Need to add a toung extension, so I can launch with out getting my feet wet.

 

[markstrimaran]

Jacking up to remove old trailer, and putting a better one under it. Maybe some bottom paint.

 

[markstrimaran]

Trailer painted, and slide under to fabricate standoffs, and set bunk boards.

 

[markstrimaran]

Not sure what to call this apparatus. Standoff tube, maybe "cow catcher".

If left about 6" above water when loading I can motor the trimaran and run it up on them.
The tube will hold it in place, then a u bolt, locking pin will hopefully keep the boat from sliding back as I go up a steep boat ramp.

The trailer has 4 standoffs, a 2x4 bolts in between them. It acts as a guide to line up on the trailer. I usually have to load up on the rough side of the lake. In a cross wind, it makes it a simple task.

 

[trip the light fandango]

Room for 4 adults.

Beach able.

8" draft with boards up.

Trailerable.

30 minutes to launch, in the dark. With minimal needed for assembly .

Unsinkable, foam laminated cored hull.

Completely dry cabin, waterproof in a rainstorm with
36" of head room.

Easy to sail, upwind ability.

Dual purpose, amas, can be removed, and it becomes a 15" fast River boat.

Built for less than $2000.00
This was on here before. I can't post to my old link, so I started a new thread. The boat has 3 years on it, since I started. It has undergone a lot of tweaking. It still has a few things that could be improved upon.

It needs primer ed areas to be painted, the dagger board/Lee board, setting a self tacking jib sail. The problem trailer fender that likes to vibrate loose.

A trail blazing conglomeration that is quite pretty when it is packed up and on the highway.
It looks really compact and ingenious on the trailer, a reverse origami ugly duckling/swan. I like the audacity in your spruiking something that is clearly not aimed at retail marketing[?] but utilizes the formula, wonderful irony, simply unbolt the eccentricities and lo and behold it becomes a runabout with an outboard, a fast river boat. It is necessarily unique and a stable platform for fishing, I tips my hat to the problem solving of your own making, I do a similar number myself , well done . A spinnaker might be fun on your craft, on its own. Another possibility is putting a large tent on the platform and run the tinny in and out and the solcat becomes an anchored go anywhere on water station. ,but you lose the sailing problem solving intrigue then. James Bond and Hobie eat your heart out, ha ,.. cheers. I wonder how this would perform if the donor centre hull was aluminium?

It would have to be a very custom built aluminum boat, as the torque applied from the amas, lever effect, and the mast tension is going to destroy a factory hull. The hull twist before I foam cored and added glass bulkheads was scary in 3 foot rough chop.
