Does any one have any words of caution regarding lifting an rl24 by the chainplates ? My chainplates run up the sides and then turn at right angles to sit flat under neath the deck ...they are about 8"x3" x1/4" ss on the inside and 11/4" x1/4" on the outside thru bolted & epoxied into place> heavy duty in other words. Attachment point is a 5/16th std D bowfitting thu the deck and into the under deck part of the internal plate. Lift is via a chain block on each side and a rope block & tackle off the stern via the olds backstay strong points.
needless to say I'll be placing some huge chunks of firewood under the boat so if there is a failure it wont go far!
Reason is a big bog up & repair after 30 something years of trailer dings ( previous trailer) grindings on the bottom and a few ugly little lay up blisters which will need much drying out & grinding
At least you'll find out the state of the u-bolts. If they have any age about them, it's not unsual for them to break. Stainless steel is a bit like that.
Personally, I'd consider the more traditional drop the boat on the grass and lay it on it's side approach.
Let's know how it turns out.
Thanks for the thoughts folks...
I agree there is some risks but the weight on each chainplate will be less than 400 kgs.. And I think I will roll the boat and do a side at a time rather than spray upside down.
Does anyboady know the larger loads placed on the side stay during heavy sailing? ...eg 4 heavy adults to windward & centre board vs full sail and a shy kite... Give the "squared law" re wind speed vs power I reckon those chain plates would get shock loads well in excess of 400 kg on a backstayless boat... The reason i beefed up the chainplate was be cause the previous anchor point for side stays was a track on the deck below the windows and it was starting to deform..I was worried about deck & hull parting company!
After recently purchasing an RL24 (#164), as a matter of course I replaced all of the rigging, but not the U-Bolts as we regarded them as permanent fixtures. Well you know the story, first sail, one U-bolt fails. After removing the remaining bolt it also had corroded through on one leg and was also suffering fatigue cracking. So if you are replacing the rigging I suggest that you also replace the U-bolts as they definitely have a limited life!
