so i sail an older hobie with unknown number of previous owners. well, said owners have drilled and attached many fixtures to the al bars. i am currently removing those fixtures, to start tabula rasa, and curious about the rivet and screw holes. should i let them be or fill them? if the consensus is to fill, with what? thanks-

If you wanted to fill the holes use JB Weld. But the filling would only be cosmetic. The only way to do a structural repair would be to weld the holes closed. Structurally there is probably not an issue here.

Hobie Masts, crossbars & wings are heat treated & anodized aluminum. Very difficult to weld. I would avoid welding as welding even after pre heating the aluminum will leave a heat affected zone and the area will be weaker that the rest of the structure. JB weld or a colorfiller of some type is your best bet.

Holes in your aluminum should be filled. Water that enters can cause trouble for you when you capsize or turtle (imagine trying to right a boat with a mast that is COMPLETELY full of water), and will just plain slow you down other times.

I think your best bet would be to fill the holes with appropriately sized aluminum rivets. Make sure you use plenty of silicon when installing them so that they seal well.
