All the hardware is stainless.

The protective/sacrificial Kevlar is attached wherever one can expect impact and scratching. The carbon/Kevlar surface is lightly sanded and faired.












The floatation is poured right into the hull, contained by a half bulkhead which is also serving the transverse stiffness and reception of the fore-aft thwart. The floatation compartment is closed with 3 layers of carbon/texilium.

The foredeck is fabricated by stretching rip-stop nylon directly from the railing to the arch, and molding directly onto the fabric. The fabric was later removed.

Far left is a fabricated detail from the thwart support.

The heel-wheel, and also the final layer of carbon prior to cutting out the bottom portholes.


All details work is immediately covered with nylon to assure smooth and saturated surface fibers.


This whole phase took time as design/re-design and fabrication/re-fabrication went hand-in-hand.

Make shift jig were in frequent use.

This is really the fun part, because details evolve as they are addressed.

Notice the integration of the oar-locks.


The foredeck is cut to fit (diamond cutting disk on the Dremel) and glued down with epoxy putty. The WEST system was the epoxy of choice. Slow, hard, surface…. hardeners... they were all used.













The gel coat (polyester) was applied as the final surface, then the skids/handles on the bottom. Cores are fabricated prior to applying the Kevlar. No gel on the surface where impact and wear/tear is expected.



The boat was tested prior to cutting the portholes.

It takes courage, and as you know, it hurts to make big holes in a hull ;)
