What you are saying makes a lot of sense. I will take some pictures of the poles and post them. I can’t post pictures of the boom fittings because they have all been removed, I only have the positions of the holes to go on!. There are a couple of blocks on the mast though, I will photograph them. I don’t know if it is possible to upload the pictures to the forum, but I will put them up somewhere.
This may take me a few days, as I won’t be going to the club until the week end.
