hi all. Any recommendations for a web site about masthead rig tuning. Sailmaker says I need to increase the rake and my b1 and 2s are too tight. Thanks

Not sure what b1 and 2s are - normally terminology is V1 and D2 for single spreader cap shrouds, D1 for single spreader rig lower diagonal. For 2 spreader V1, V2, D3 caps, D1 and D2 diagonals. Some of the below links will have diagrams.

There are numerous good guides - here are some ranging from the concise to the full monty from Selden. Suggest make sure your turnbuckles are well lubricated for a few weeks beforehand so that when you undo the locking nuts or turnbuckle bodies themselves you don't strip the threads. We use CorrosionX and it is superb but spendy - but worth it. Also suggest don't use shifters rather exact fitting spanners on the nuts else you could burr them and have a drama. Looking up the mast track before, during and after is critical to ensure the mast remains in the lateral plane the whole length else it could buckle. Is your mast keel or deck stepped.

R13 thanks. Looks like a bit to study. If I'm not confident i will get a rigger. My boat is a x-yacht 372. Keel stepped 2spreaders masthead. Is corrosion x a penetrating liquid or an anti seize? Cheers

See full description of capabilities here;

The Selden publication that r13 suggested is well worth reading, it describes pretty much all standard rig configurations, and even if your not keen to do it yourself, it's nice to read from a manufacturer how it should be done. I like their rig tension method with a 2 metre rule, and advice on various wire percentage of breaking strains!

The original post asks: hi all. Any recommendations for a web site about masthead rig tuning. Sailmaker says I need to increase the rake and my b1 and 2s are too tight. Thanks

Sorry I know it's not helpful but it's just what occurred to me and thought someone might understand and have a giggle

+1 Thanks for finding this R13, has to be the definitive work on the black art of rigging.

Ok good one thanks for clarifying.

Thanks heaps r13. Your info was great, I can google but you put me in the right direction. I wasn't born a rigger but I very well may die one. I enjoy doing things myself. I have a lovely boat and new sails fitted and I can't wait to impress myself. I had a giggle thanks to wander66. Cheers and thanks again R-Man

Yes stockie. Me too. Who said the internet is a waste of life

Thanks Captainyanti and all much appreciated. Just to extend on the "don't strip the threads" text, stainless steel fasteners have a high potential for thread galling if it is not managed - see my input on this about 1/2 way down in the below prior thread which also has a lot of other interesting info.
