new member needs hull choice guidance

[Pericles]

LJ,

We're just thinking outside the box.

For Xmas, I'd like an package of instant boat mix. The kind with instructions that say, "Add water and stand well back".

Well I don't have a parrot so anything I say should not be taken seriously... I'm sure jack's comments reflect his experience.

Actually there are hundreds of modular built catamarans out cruising the world's oceans. These are built and transported in pieces and assembled on the beach, no sheds, etc. They are lashed at the joints. http://www.wharram.com/

The Kelsall concept looks reasonable but the center module is still too wide. What you want is something with more even divisions, i.e. joints somewhat inboard of the hulls. Or separate hulls, crossbeams, and deckhouse. Or just two narrower hulls with a deck between.

Remember that the complete hull & deck shell (in any material) will represent only 25% (money & manhours) of the project.

Unless you are willing to undertake something like a house move (two pilot cars, roads closed, etc.), you will require a custom design. Due to your lack of experience in boatbuilding and your geographic shortage of experienced boatbuilders, this design package will have to be really complete. Expect to pay a lot for this, and (if well done) it will be worth it.

Buying an existing boat will give you much less grief.

All the best, Tad
