Re: Building Meerkat, a very small catboat
Putting some camber in your deck, even just a little bit, will make it much stiffer. Curved thin structures give you better structural qualities for their weight--think of an eggshell. Plywood only wants to bend along one axis a a time, right? You can use that to your advantage to eliminate any risk of oil-canning between the frames.
I would definitely add a little bit of camber into your deckbeams. It really won't add appreciable extra work, but it will improve your structure all out of proportion to the extra effort. .
Amphibious Macroplankton Oughtredia doublendus
Mostly found frequenting the littoral and estuarine zones in the southern half of the Salish Sea, though sightings have been recorded both north and south of this area, and occasionally, but rarely, inland, in freshwater environments. This species lives on micro-brewed beer and dutch-oven biscuits,and displays brightly colored nylon and gore-tex plumage during the rainy season. Approach with caution!
