Personally, I don't see any issue with using long extensions all the
way in the mast. This is what I've always done and I've never noticed
a problem, even with race sails. The effect that the extension will
have on mast bend is so minisucle it's really not worth worring about.
I'd keep the extension long- you're going to be annoyed when you need a
long extenion and you don't have it.
If you do end up cutting an extension, make sure you idiot-proof it in
some way so that you always have enough insertion into the mast. When
I bent a long aluminum extension, I cut it to make a short extension.
I used a center punch to knock some metal into the holes in the top 6"
of the extension. That way I physically can not get the pin in these
Just my opinion.
