Bulkheads, dagger board case and chine logs.

Since my last posting I have manged to snatch a few hours here and there to get some more work done on the goat.  Bulkheads 1 and 4 are now complete apart from fitting a waterproof hatch of some type so that I can get into the buoyancy tank for storage and drying out if necessary.  Below is a pic of the full set, BH1 to Transom (still without a ruder hole or outboard engine cut-out).

The dagger board case has also been cut out and assembled but not finished.  Below you can see the internals of the case having had a couple of coats of epoxy to seal the wood.  I was thinking of adding some glass mat to the inside to add some abrasion resistance but with only 3mm of clearance and final finishing of the dagger board to be done it will be left with just an epoxy coating.  The aft and possibly the front end of the case will have a tough rubbery foam applied so that the dagger board has some degree of protection when we touch the bottom (at speed).

Lastly, the chine logs have been cut down to size and temporally held in position using a few screws to check that the cedar takes the curve with no problems, as it turns out I need not have worried as it is flexible stuff.  A few builders have suggested trimming the inner-top corner of the chine log to lose the sharp edge and remove a potential dirt and water trap, both of which are good reasons to get the router out.  As you can see below the chine logs have a pleasing bevel and I'll hopefully get these glued up this week.

  1. Looking good! I'd continue the bevel on the chine log just short of the hull side. This is how much I beveled mine

    and a bit of sand and junk still gets trapped in the V formed by the tiny unbeveled bit.
