New builder here... I was advised to read this thread prior to starting. I've read it, but I'm confused about what the point of failure was for kpbroughton. Can anyone explain it to me? I understand that he believes it is due to the keel trough wicking water up through the keel trunk, but did he ever discover where the water was actually entering the fiberglass/epoxy? This seems like pretty substantial damage for water wicking up from the keel trough.

Same here - I'm a new potential builder as well.

Anybody ever determine what the issue was? Have to agree with John Harris that it looks to have been a defective plywood issue. Wow...

And what happened to the boat? Did the poor owner burn it? Thread just stops... :/

Definitely making me cautious about where I buy my plywood if I build from plans...

Hi prospective new PS builders,

I must add that before and during my own building of Puffin, completed in 2018, I read - and reread - every PS forum post, most PS builders' blogs, and collected my own listing of forum threads related to topics. That and communication with CLC staff at WoodenBoat shows convinced me of many things but chief among them were to ensure that all wood was sealed with epoxy (or FG and epoxy), and if in any doubt, reapply. The consequences of subsequent water intrusion into deeply inaccessible portions of the finished boat are potentially so devastating.

My other bit of advice is to strongly consider sourcing your plywood directly from CLC. They're in the business of procuring quality product. I realize one might find suitable material more locally, but then the burden is on you and some local plywood supplier who may not have your boat's seaworthiness foremost in mind. The most expensive part of the build is your own time in the process; the potential to save a bit on materials up front can prove false economy.

Enjoy your building process. It's great fun, and you'll have a fantastic little boat.

All the best,
Mark

Here's what I did to protect the vulnerable edge of the centerboard slot. I put several thicknesses of glass on that edge followed by one layer of Dynel cloth. I hope my crude drawing illustrates this. Dynel is known to be good at resisting abrasion. I also coated the slot opening (and the rest of the hull below the waterline, centerboard and inside of the slot) with epoxy mixed with graphite powder and Cell-O-Fill. The Cell-o Fill makes it hard, the graphite powder makes it slippery. Such additions diminish the slot width insignificantly and I've had no problems with either a sticky centerboard or slot abrasion. The other photo shows the keel shoes I added fore and aft of the slot. I figure this further protects the slot from abrasion, particularly when sliding the boat on and off the trailer. It also keeps the slot off of the trailer's keel trough carpet allowing it to properly dry whether from lake or rain water.
The other photo is just a gratuitous one of "Luna" in her element.
Cheers,
Bob

A little off topic here.

Hi Bob,
Luna looks great. I really like the color scheme.

The gaff looks longer than John Harris’ design, is that so it will rest on the gallows when the mast is lowered or is it just for appearance?
There is a line or halyard from the mast to the end of the bowsprit where I would attach the spinnaker clew. What is the purpose of this line?

Hi Wayne,
Thanks for the kind words.
Yes, I made the gaff longer so it would rest on the gallows (just like you thought). It works well whether the mast is up or down. When I lower the sail it's nice not having the gaff fall into cockpit if I happen to let go of the peak halyard and makes flaking the sail and putting the sail ties on, a breeze.
If I understand you correctly, the line from the mast to the bowsprit is the spinnaker halyard. I often leave it there when I don't plan to use the spinnaker. Otherwise, I keep it attached to the ring at the bottom of a shroud just above the chainplate where I can easily reach it when needed.

I think the extended gaff is a great idea, and will probably be my next lock down project.
When the mainsail is lowered and the gaff drops into the cockpit, I find that sometimes it can get caught up in the various halyards making raising the mast a trial and error affair while untangling the lines.
