HullShape 1108

Modified hull shape, symmetrical hull, asymmetrical deck, clearance between rear beam and designed WL is around 90cm, more than the Radical Bay 8000, but still a bit low. Hulls are fatter but WL beam is just 1cm more, WL to BWL is almost the same, almost 13. Next thing that came to my mind will be to further move the cockpit seat towards the trampoline, amplifying the aft berth space. Under sail the cockpits and entry hatch will be protected with a slick (hopefully) spray/sun hood.

ReadingDuty

As you can imagine I'm trying to get as much info and knowledge on designing cats, while reading stuff on the net the words of Ted Clements just brought a smile on my face.

"By design, a monohull sailboat almost invariably has to carry ballast well in excess of its ability to float it in the worse case. Ballast in itself is a useless lumpen cargo that strives to sink the boat from the moment it is launched. The decision to purchase it and float it around has to be counter-productive, if you have a choice. The nice thing about sailing catamarans is that they manage to stay upright by cheating, (all form stability, no ballast) so; you do have a choice."

Clearly the world is split into smokers and non smokers, cyclists and drivers, catsailors and monosailors etc...

EvolutionProcess

I'm currently thinking of a redesign. I've been pondering a lot these days on the actual build process. This cat must be practical within my budget, not just nice. Currently I'm debating wether it is efficient having asymmetrical hulls, especially when I'm considering building the hulls in female moulds. That would mean 2 female moulds, which is not good. I would go with a redesign - new symmetrical hulls, keeping the B/WL ratio, but with asymmetrical decks. Why female moulds ? Sanding the outside of a 9m cat is not an easy and fast process, quite the oposite. Female mould will save considerable time from the build process, also that will imply foam. This is probably one of the many turning points of the project, untill a satisfactory solution will come up. Foam will be 3 times more expensive than a wood core, most probably.

Did I mention I want it to fit in a standard 40' container ?
Just in case...

Beams

Working on the beams. Blending the mountings into the hulls is not easy, rear beam proves to be difficult. Will get it sorted eventually.

InteriorPartitioning 0408

Getting an ideea of how is the interior going to look like and how much space will there be inside. Next major design issues will be beam mounting points/connection system.

HullShape 0308

Hull flairing is relatively subtle, entry hatch and cockpit added. Current model will serve as a guideline for a final model once the building technique will be chosen.
