Hi Jim I know my build is not an ECO 5.5 or 6, but I welcome you to come and visit us. We are building a Voyager 122. Northeast NC. Drop by on your way to the OBX. Cheers Patrick

French people always jumping conclusions. I did not doubt the sea worthiness, altough you can read the comment like that if you want. What I was trying to ask more is that would you see the boat

I am interested in building one of your catamaran designs. Iused to own a Wharram Tiki 30 with a pod and I am looking for a design with more comfort which can be trailerable to launch site approx

It's a stretch between the Carolina's and the Canadian prairies, but you're welcome to have a look at my ECO 6. There is an ECO 6 in Florida built some years ago with the original shaped bow. The

Howdy all, New to the group, I am looking at the ECO 5.5 and 6 - anyone have one near the Carolinas??? I would like to see one in person, even if it's a project in progress. Jim

I know. It is not my idea about what a sprit is. The term is used for both. It's not my invention. Only a Wishbone is a Wishbone, and no sprit is a sprit.? We let it stay as is.

There are obviously multiple incarnations of what is meant by sprit, The only one I was aware of is https://en.m.wikipedia.org/wiki/Spritsail But you are the designer so I am happy to defer.

To get the terminology right. An old and generally used terminology Picture Birdwatcher from Bolger. This is a sail with a sprit The aft mast sail of the Wharram boat also has a spirit. It is not a

Wharram calls that a wishbone and it is there on the aft sail because the sail is loose footed and projects behind the hulls. It is not part of a standard wingsail. Why wingsail? No idea, you could

That is a great idea. I will be using that system for sure.

First or second photo linked ? Thank you

What a question. What do you want to imply? Of course, my boats are structurally sound. What a question! The seaworthiness is a factor of boat handling. Bernd

Look at the picture. On the aft mast. There is the sprit

I would use the sloop rig

Thanks, Philip In all my construction manuals, this is my first advice. It is boring to do but can be quick See this video I made some years ago. https://www.youtube.com/watch?v=V1GfJ-XHwf8 It is

Let me ask Bernd please What sail plan would ***YOU** Put on a new build 860 open. For low cost Ease of use Best performance Because im confused with all the differnt options. Thanks

I am personally still thinking of building eco 6, But i would have question for Bernd, Is eco6 as of its in your plans blue water ready ship structurally? I see almost all suggesting going KD860 for

Alain,apply the epoxy before building. Use the squeegee method. You put the sheets on top of each other on saw horses and start with the top sheet by pouring some epoxy on, distribute? with

Hi Bernd, There is no sprit on the Wharram wing sail, just a short gaff which is not heavy made in laminated ply. Obviously carbon would be lighter. The gaff lives in a sleeve at the top of the sail

These questions that you are asking Bill are very similar to what I went through when deciding on the rig for my Eco 6. I designed my own hybrid rig which had elements of the Wharram rig, and a square
