Crack in mast support beam
Some advice please.
I had just finished off getting my Vivacity 20 yacht ready for the coming season when I made a rather alarming discovery (that's sailing for you: a succession of alarming discoveries interspersed with the occasional sail!). I noticed a large crack in the arched beam that runs under the foredeck around the bend where it dips to run under the port side deck.. The beam is presumably intended as a support for the deck-stepped mast. On investigation, I noticed that this had been previously filled (with silicone!) and painted over by a previous owner. I bought the boat last year and sailed all last season without any obvious problems, and for all I know the crack may have been there for years before I bought the boat. On probing the crack, which runs all the way around, I found there was solid material beneath (i.e. the beam does not appear to have broken all the way through). I am wondering whether all that has happened is that the GRP that sheathes the beam has cracked and whether I need to worry about structural integrity? Why has the crack reopened? Has this been caused by mast compression (maybe overtightened shrouds)? I intend to fill the crack with a good epoxy product: will this be sufficient, or do I need to investigate more radical solutions? These old Russell Marine boats were built pretty chunkily, so I'm hoping that I don't need to embark on major repairs or adaptions. |

Crack in mast support beam
I may be telling you something you already know, but a 'trick' I have used
to fill cracks is to get a syringe with a large needle and inject the epoxy deep. Here in the states, these syringes and needles can be bought at a farm supply store. They're used for cattle. Could be that you just found a natural fault in the wood. I would get the silicone cleaned out, fill the crack as deep as possible and keep an eye on it. If no other stress cracks open up, you're probably OK. wrote in message ... Some advice please.
