The Miquanaut MK2...

The scale model process goes on... I have made a mk2 version of the Miquanaut.

I had to. I put the first model on the top of my car and drove off. By the time I had that awful feeling 'you stupid forgetful **** ' it was too late.
Hopefully somewhere a little boy is happy playing with it at bath time!

Anyway, the first version seen in previous post ended up looking too similar to my Valley Aquanaut, and I thought there's no point in copying what's already there, so after playing around with the Kayak Foundry I came up with a new design which is more of a pure day boat and will hopefully be a boat I can 'grow' into for more challenging water.

The Aquanaut is a great touring boat, but not that fast or light!

Designing a sea kayak which to be quite honest is something I don't have a lot of experience of, is a lot harder than you would think. Reading up there are lots of subtle design features that will affect the way a boat handles, so I have tried to incorporate what I consider the best features of other boats, which hopefully will come together in the final design.

By tweaking hull forms, sheer lines, beam etc, changing length, adjusting rocker, position of the cockpit etc, all these factors can be seen in projected drag tables at different speeds, stability for a variety of paddler weight and loads.

I've tried to come up with a boat that will be light and manouverable with the amount of rocker built in, a fairly flattish hull under the cockpit similar to a Romany for good surfing qualities, and a fairly aggressive bow and stern. The drag tables indicate it should be quite fast for a 17 foot boat too.

I've printed out all the forms for the hull, and am now trying to get a source of western red cedar 6mm x 20mm cove and bead strip. There are companies in the UK who sell it at quite extortionate cost; it may be cheaper to import it from Canada!

The alternative is to buy 6" x 1" boards, plane and strip them myself, then router in the edges.
A lot of work, and a lot of sawdust too. I estimate I'll need 1000 feet of the stuff.......

There are some fabulous designs around on the web, Blue Heron Kayaks, and Guillemot Designs are the ones that explain very clearly the whole concept and well worth having a look at.

And for the bespoke strip built boat have a look at this!

In 2 weeks I should have the forms and strongback constructed, so keep viewing..
