mast extension ?

[gramos]

i need to make and fit a permanent bimini , but the boom is too close to my head ! so i intend to add 500mm to the mast at the top so as to allow the main to lift the boom end ,where the clearance is needed,i will need a z spars 600 e section to add to it anybody got a section ? and how should it be fitted ? so as to retain the strength .

Adding a half meter to the top of the mast so you can raise the boom seems like a serious operation. It will make some serious changes to the design of the boat. The sailing dynamics would change quite a bit while looking horrible.

The approximate 2' addition should not be a problem. I'd talk to a rigger or NA about where you should splice it in, however. If you do it at the top of the mast, you are adding weight at the worst possible place. Have seen lots of masts withs splices in the lower sections. Better placement of the weight of the sleeve could be the reason.

If the aim is to only lift the end of the boom, I presume the gooseneck will stay where it is, why not just get the foot of the main recut to achieve the same thing, would be cheaper IMHO

Ditto Whimsical but you don't need to move the goose neck just have a shelf reef cut to shorten the leech not the luff. Have your sail maker visit the boat and take a measurement. Tell him where you want the boom to fall.

Yeah that is what I was trying to say

Previous owner on my boat raised the boom fro the same reason ,but never bother to compensate the mast for it . Instead when the got all new sails ,the got a bigger Genoa . My self, that less sail area doesn't bother me ,I'm a cruiser ,never in the hurry ,and my glad they have done it ,because I'm in a process ob building a hard top bimini.
