Re: naval ingeneer for own design

trimi, have you thought about buying a set of plans for an existing trimaran design? Good plans for a home-build will give you the construction scantlings and recommended materials. In the long run I suspect it will save you money, time and headaches.

Re: naval ingeneer for own design

Trimaran plans are readily available and are proven designs.

If a person is going to commit to 1000s of hours in boat construction labor and spend lots of money on material ...why would anyone take a chance and design their own boat?

Re: naval ingeneer for own design

When you say "designed" what do you mean? Because a structure like a trimaran with a mast and stays, the structual questions are the starting pont of the design. Do you mean you made some drawings of what the boat might look like? And now you need to fill in the insides? If the latter, i recomend as above said, get some plans and start there. You have extreme forces at work on the crossbeam under the mast.

Re: naval ingeneer for own design

Yes i looked to as many existing plans i coud found ,but my needs are 2 cabins -heads,and enough deckspace to transport socasionally 20 passengers,sitting on seats, on a daytrip to a national park.The draft with this load can not be more than 4 foot.What i call a design just meets this. Does anyone now a plan i can use ?

Re: naval ingeneer for own design

I'll second the boatdesign dot net forums. You're looking for a naval architect not a naval engineer. If an engineer designed it, it would be indestructible but it would never float.

Re: naval ingeneer for own design

I would contact Graham Byrnes of B&B yacht designs in North Carolina.
He has many years of experience in the design of multihulls.

I am currently working with him building a 45' power catamaran of his design.
He has done many, many multihull sailing designs.

His website is

B & B Yacht Designs

He can do CNC cut files or mylar templates for the vessel along with the plans and engineering.

Alan Stewart, who is the defending 1st place in the Florida Challenge in a Tri of his own design, also works with us.

He shoved off this morning to defend that race.

Contact Graham, he can do anything you want.
