Kit Cat #8

What's immediately obvious however is that a similar bridge will be required at the rear to support the weight of whichever type of motor is used; although they're more lightweight electrical outboards appearing by the day. The tail-structure half the size of the seat, which with the backrest foreshortened means that both parts have been produced with a half-dozen 300mm square panels of laminated foam.

There's a lot of work going forward to make this a usable kit, but then the benefit of feasibility studies like this is that they contribute toward alternative build methods that can be incorporated elsewhere... should we return to the outline last featured for the catamaran, which is looking more attractive after all in the light of today's.

Kit Cat #7

Position the seat with a 3' overhang at the rear and 5' at the forward end. The issue will be whether sufficient low-density foam can be packed beneath a seat to provide sufficient buoyancy, but the sums suggest it may.

Kit Cat #6

Here's the finished article, and not unlike the one Lincoln's sat in at the capitol. To my mind too, not unlike the legendary IKEA armchair that we sit watching Netflix in.

I have added supplementary panels of foam around the underside of the seat, which improves the structural strength at the same time as providing the static buoyancy that will be required for this to float anywhere near level upon entry.

The foam here heavier than it need be, being an off-cut, whereas this will be a place to fit your lower-density foams that are less expensive altogether.

Few rough edges that need rounding off, but good to think that at double the scale we'll be sitting here at this stage enjoying our cappuccinos.

Kit Cat #5

We'll be chilling on the beach over a picnic when not on the water, so I've inclined the seat at an angle I can picture myself sitting at with a straw boater and Pimms. I have also filleted each of the internal joints here, though it needn't be a work of art.

Kit Cat #4

Similar method with the seat-back, though again an option will be to fix this in place using only adhesive sealants from a gun.

Kit Cat #3

I've pitched the seat at 50% depth and fixed with screws from either of the sides. A benefit of laminated backer compared to 6mm plywood is the fact it can be cut with a blade in seconds like a sheet of plasterboard... ideal for iterative prototyping.

Kit Cat #2

Add bolsters to the base of the seat. In time we're looking for all-foam construction using only adhesives for this module, but for now it's bits and bobs lying around the workshop.
