Shroud Chainplate Consideration
Greetings all. Have been doing some searching on this topic but have not found much if any info on it so I want to open it up for discussion. My girlfriend and I own a 71' Seafarer 34 that we are restoring. The aim of the boat is to be a coastal cruiser first and a blue water boat down the line but I am of the mindest that I want to make all modifications for blue water now, especially concerning the rigging. The shroud chainplates on this vessel are not plates, they are U shaped 1/2" 304 stainless rings that are through bolted with backing plates to the hull/deck seam. The seam on this boat is structurally laminated and has no fasteners or mechanical retention, effectively there is no seam. These rings are epoxied into this area and look to be quite formidable. As pictured there are three as this is a single spreader mast. So, I would love to leave these alone, they look good and seem very strong. I have an idea to make them even stronger by linking them all together with a single backing plate that will be about 3' long. This will obviously follow the curvature of the hull and will also act as a bonding plate for multiple grounding wires to dissipate lightning strikes. I think it would be prudent to remove at least one ring from each side of the vessel to check for corrosion where they pass through the teak and deck but other than that I would like to leave it all as it is. My question is does anyone see a problem with this design? Is it unsafe, should I have I make the backing plate an "L" and epoxy it to the hull as well or is that overkill? Any input would be appreciated, thank you in advance!
