The decision to switch from the standard shroud lashing pads in the plans to regular bolt-on, external chainplates created a lot of extra labor and expense. But regardless of that, I firmly believe it is well worth it for the secure means of attaching the Precourt terminators and deadeyes I will be using for my shrouds, as discussed in an earlier post.
I fabricated the chainplates myself to get the exact dimensions and fit I wanted. They are 3/16" thick by 1 1/2" wide, and 12 inches long. 316 stainless steel plate is hard to drill, bend and polish, but eventually it was done, and I'm well-pleased with how they look. I didn't want a highly-polished glittering yacht look, just the rugged purposeful appearance that externally bolted-on chainplates exude. (Note that I painted over part of this section of the topsides when painting the sheer and cabin sides. The green topside paint will be brought up to the bottom edge of the sheer stringer. I just wanted to get everything in the way of the chainplates painted so I can permanently bolt them on. It's easier to bolt them on at this point, before I install the portlights, as I can reach through the window openings to back up the lock nuts on the inside - important considerations since I'm working alone).
This morning I completed the backing plates for all the chainplates and bolted them up to check fit. They will be removed and then permanently installed with 3M 5200 as soon as I polish the backing plates a bit. Then the windows can go in as soon as that's done.
Here you can see the clearance at the tops of the chainplates for the Precourt terminators. None of the ready-made chainplates I could find, like Schafer's, had enough length above the sheer to keep the terminators from hitting the cabin when the shrouds go slack. These do. Note also that the pin size for the terminators is 1/2 inch. This will certainly be as strong as any part of the rig. Each chainplate is through-bolted with four 5/16" bolts.
Here's a view of the inside backing plates in the starboard hull. I didn't want to use individual fender washers for this application, as it is all too common to see them literally compressed into the wood by the strain that is put on the chainplate bolts under load. (This part of the interior is still only epoxy coated. It will get sanded and faired and then finished with varnish).
I'm also preparing to permanently install the companionway hatches. Here, they have just received the first coat of paint after fiberglassing, fairing and priming:
The cabin tops and coamings are done. It's hard to see the edges in these photographs, but I've laid-out a non-skid pattern for the walking surfaces on the cabin tops.
Here you can see the non-skid somewhat better. This was the final paint coat that I applied this morning. When this has had time to completely dry, I will permanently install the Bomar hatches in the openings on the forward ends of the cabins. I placed an order yesterday for the remaining primer, paint and sealants to complete all these jobs. Within a couple of weeks I should be moving these hulls out in the open to make room in my shed to bring in the beams that are still in my girlfriend's garage where I built them. I still have some sheathing and fairing work to do on the three beams before they are ready to prime and paint.
