Relocating Shroud Plates

[ROAM1962]

The galvanised shroud plates on the classic 1948 sloop I am restoring are normally on the outside of the hull, but recently I have managed to get the original desigers specs. They say they are to be fitted on the inside. I suppose this is more aesthetically pleasing. The problem is that I am not sure how the hull planking will cope with the shroud plates bolted in the other way around? There are backing pads inside the yacht with the current set-up. How would I reverse this. If I do fit the plates on the inside I would need to couter-sink the bolt heads in 3/4" planking and the fair them somehow - I am not convinced there is enough space to countersink the heads in 3/4" planking. Would anybody know how other boats are set-up with regard to internal shroud plates?

They may have been put on the outside in the first place because someone became tired of them leaking from the deck on to his bunk, or the original builder expected that they would leak and so convinced the original owner to have them fitted outside.

The chainplates on my Hillyard are fixed inside the hull and come through the (canvas on ply) deck inside the toerail. They are fixed with coachbolts which are countersunk into the planks.
I regalvanised the chainplates and refixed as the old bolts had rusted and popped the fairing. At the time I seriously considered moving the plates to the outside of the hull as the through-deck arrangement was a source of leaks. After taking advice I caulked the plates with cotton and faired with white lead... and am still getting leaks because of flexing.
At the next re-rigging I will bow to the inevitable and move the plates outboard. The only disadvantage I can think of is upsetting the clean lines of a faired carvel hull. Practicality wins!

Another vote for outside

Inside chain plates are far more trouble than they are worth, and a very fertile source of leaks, hence rot. I had a boat with inside chain plates, many years ago, the boat I have now has them outside and I have had them all off, regalvanised and refastened with new bolts with no trouble at all. A yard neighbour working on a much younger boat which had been seriously neglected by a YM regular contributor who had best remain nameless (but I won't be buying any boats from him!) tried to get the inside ones on his boat out, to do the same (he is a professional shipwright) and gave up in disgust.

Tiller Girl was the same as the other folk here - inside chainplates and a history of leaks at that point. A survey recommended changing to outside quite a few years ago and that was done - no leaks now. I wouldn't do it either.

Thanks for that response! Through popular demand, Roach's chainplates will remain outboard! One thing less for me to do too - and that is quite a rewarding thought on this restoration.
