Cal 39-2 Chainplates
sailtheboondocks2013-05-05 04:35
Hey group.
I have a 1980 Cal 39-2 and am repairing all her wounds. This includes the stressed, and now weeping, chain plates. It's not too bad, but I want this boat to be tops.
Here's the Q. My chain plates week a bit and need at the least rebuffed and re-bed. For those who know Cal 39's well, the shrouds are directly mid deck...basically in the walkway. I really like the look of hull chain plates on the port and starboard sides such as the Crealock 37, for example.
Would it just be stupid, way too expensive, not worth it, etc, to consider making the change if I was to replace the plates all together? Is that setup as strong/stronger/weaker that the current setup?
Appreciate all help on the matter.
Boon

Brian,
I asked the same question about my Cal 29 about a month ago. You can look
it up in the archives, but the short answer was that it would likely
compromise the structure of the boat. If you'll have trouble finding the
thread, let me know and I'll forward it to you.
Cheers,
Alex.

Sure you could do that. I would place the chain plats just forward or aft of the bulkhead that they were in. I would then bolt them through the hull sides so that the bolts pass through the fiberglass tabbing that tabs in the bulk heads. You might want to beef up that tabbing or ad an L bracket on the inside to ensure that the load is transferred evenly on the hull and bulkhead. Depending on your head sail you might loose a lot of sheeting angle causing your pointing ability to suffer.

Just to clarify, my reply (yes) was an answer to the first question.
Seeing the second I think the other thread established that it was weaker.

Boon,
Before you move the shroud chain plates you really want to think pointing ability which, to my mind, outweighs having the shrouds in the "walkway". Although I wouldn't presume to know the mind of the departed Mr. Lapworth I am quite certain that he didn't locate the shrouds where he did for cosmetic reasons. If, as you say, you want the boat to be "tops" don't try to redesign it into a Crealock 37. Crealock and Lapworth were very different designers with very different design criteria. Lapworth knew what he was doing when he designed the 39. Don't mess with it and she will never disappoint.

Wayne

Hey group.
I have a 1980 Cal 39-2 and am repairing all her wounds. This includes the stressed, and now weeping, chain plates. It's not too bad, but I want this boat to be tops.
Here's the Q. My chain plates week a bit and need at the least rebuffed and re-bed. For those who know Cal 39's well, the shrouds are directly mid deck...basically in the walkway. I really like the look of hull chain plates on the port and starboard sides such as the Crealock 37, for example.
Would it just be stupid, way too expensive, not worth it, etc, to consider making the change if I was to replace the plates all together? Is that setup as strong/stronger/weaker that the current setup?
Appreciate all help on the matter.
