All the best with your boat Glenn, & also thanks to Phil who's very articulate in his expression of concern, please also read the link I supplied from start to finish in context from original expectations to type proven results, although the poster is still apparently satisfied & convinced on it's merit has even so, ended up with an unusual & hard to shift/sell item- the same resources put into a conventional design could have & should meet expectations & have high resale & therefore owner satisfaction, the issue of seaworthyness however remains in question to me on the featured vessel of beaus boat http://www.cruisersforum.com/forums/...boat-9093.html learning from others experience is time well spent.

Is there truly something to the no bow wave - straight hulls idea?

I doubt so, the full size creation does'nt seem to be bearing out the theory. Personally a box boat(barge) with a swim end forward & cutaway atf for the stern gear would be my preference over that creation. Jeff.

About Beaus boat.
That whole thread would make the late Edmund Bruce turn in his grave.

That was a long night. This was just a concept suggested to me. No one is holding a gun to my head. Have contacted Peter & Stu and hope to hear from them soon. To be fair have google sketched to the best of my ability the original plan. Had to do custom as I am 6'4" tall and I don't plan to be ducking under bulkheads for the rest of my life. Extra windage I know but I plan to get blown around anyway. I accept the lesson learnt - thanks.

Thats looking a lot better.

I do think that the underbody should be extended right to the turn of the stem. And the transom should not be immersed, but end flush with the waterline.
Just a matter of adjusting the bouyancy factors.

Since your design looks very strange, I'd say you should find a designer who actually knows something about sailing catamarans. What you drew would pound like crazy in a head sea, and probably has lots of other things wrong with it. It takes some measurements and some math to know just what else may be wrong with it.

How much of this project will you be building yourself. A 60 foot boat is ginormous. There are a fair number of pros who have taken 10 years or more to build such boats (actually smaller 50 footers). Though money could be part of that. If done solo this is a project for someone who likes to build moreso than sail. Designers probably only get a few clients in their careers, who can do a big boat and make it look reasonable. Of course if someone else is building it for you, and you have good reason to believe they can stay on budget... I haven't heard in it boats, but in other fields there are a lot of people who will just keep building until you run out of money, knowing all along that will be the outcome.
