Spent today on Great Sandy doing preparatory work for repairing a section of laid decking on the cockpit sole. Skinnydip is earning her keep as a tender.

Was a beautiful day out on the water, with a few of the local pirates dropping by for a yarn. :D
So do you measure how much work was done by the yarn?

More yarns=less work? :D :D

More yarns + less work = pleasant day. :D

I've spent more time today repairing the laid decking on the sole of Great Sandy's cockpit. It involves cycles of filling cracks along the timber planking with epoxy glue applied from a small syringe, sanding off the excess, then repeating.

I've been putting this job since we cruised Great Sandy last year, so it feels good to start getting on top of it. :D

Just remembered a pic from a couple of years ago showing the laid deck cockpit sole.

Finished epoxy filling of cracks in Great Sandy's cockpit sole planks today. If the rain holds off tomorrow, I'll sand off the excess epoxy.

Another great day out on the water. :D

You're a hard task master cape man. So here is the story, with the first two steps illustrated with pics taken today:

1. 11 out of 13 cockpit sole planks cracked, letting in fresh water and hence conditions for rot, so need filling/sealing with epoxy glue - pic 1
2. Sand off excess epoxy and remove totally failed sections of caulking seams, then cover voids with waterproof blue sealing tape given rain is threatening - pic 2
3. Next up will be replacing failed calking seams (where blue tape is)
4. Next step will be repairing other caulked seams - blow up pics 1 and 2 to see what's involved
5. Next step is to decide how to protect repaired sole - oil, varnish, other, or do nothing and rely on regular saltwater sluicing?

My first thought is oil, but the varnish will protect the epoxy you are squeezing in the cracks. Teak?

Celery Top Pine. Agree it would be nice to oil, but varnish will protect epoxy better. If varnishing, will need to mix non skid beads into final coat.

It's taken more time shaping and fitting the #4 starboard plank to plank #3 than has been the case with earlier planking.

This is because there is a greater change of angle between #3 and #4, requiring a rolling bevel on # 3 that tapers down to less then 1/16" on its outer edge. No room for error with the block plane.

I'm using 1/6" plywood for planking in an attempt to build the boat under 40lbs. If I used 1/4" plywood, the outer edge wouldn't need to be as thin, and I could have worked more quickly.

Satisfying work. :D
