Chris—

Without the support of the toerail, the chainplates are far more likely to flex and if they do, it will cause the chainplates to fatigue. I think you do need to incorporate the chainplates into or with the toerail.

Don't forget, the angle of the mast tangs needs to be modified to match the angle from the new chainplates, which are now further outboard.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

I've seen some older boats with outboard chainplates that have a sort of "rub-rail" (for lack of a better term) below the toe-rail, with the chainplate bolted below that. The chainplates bend over the top of this rub-rail, and are thus held just outboard of the toe-rail.

I too like the idea of moving the chainplates outboard...

but eventually compromised on this;



Full saga here

You will sacrifice a few degrees of pointing ability with the chainplates mounted outboard. Not a disaster but something to be aware of.

I think chainplates can be seaaled properly through the deck. gtod's link is one example. The other issue is that most leaky chainplates have been ignored for 20 to 30 years. Properly done, which requires the most work, will take the longest time. Pulling them for inspection in 10 years and rebedding them won't take as long.

I've also seen set-ups with wood blocks under the chainplates to avoid the extra bend over the "rub-rail" (is there a better word for that?).

I usually stop and think real hard whenever I'm contemplating changing something the guy that designed the boat thought was important. Just sayin.

Na, this ones easy jrd... there is no reason that I cannot get the tangs to be within an inch of where they currently are, so no geometry changes will happen, just structural strengthening of the "known to be weak" Alberg 30 chainplates.

No one questions the reinforcing of the cabin top from the inside where the mast step is on Alberg 30's (the famous aluminum beam retro fit), nor should it be a problem to move the CP's outboard. I just have to make sure the rigging alignment stays the same, which like I said ...should be easy...
