From the picture earlier in the posting
, I think that I would call this a houseboat, not a catamaran
. You can not expect to present all that surface to the wind
and the waves even just off the coast. Too bad it is lost
. It would make a nice (if rather ugly) home on a lake. With a patio on the roof, it could be a comfortable inland home.
I pray you do not judge all self designed catamarans on the fate of this one. Did the designer
have any engineering knowledge. The information to calculate what it should have been constructed like it available in books
and on the WEB. "Elements of Boat Strength" by Dave Geer springs to mind. Combined with others and tools like Engineering Toolbox on the WEB, it is possible to construct something that would be appropriate for coastal cruising. There is a reason that boats look like they do. If it doesn't look like other boats then you can expect problems in your design. Others have tackled these problems before us--and their solutions, not so oddly, come out looking the same way. It just works out that way.
I am particularly struck by the back-stays tied to that flat roof in the back. Was that supposed to work? Lots of stress. 65 feet is lot to self design. How many bedrooms did this thing have?
