[quote=Edchris177]Sailors, always give a little thought to the loads involved when deciding how to attach/secure an item.
If we are talking a mast head plug, ie Hobie, Nacra etc, from legacy boats, or a mast base, realize there are essentially no dynamic lads on the part. The rivets only serve to hold the part in place, same goes for the end cap of a H18 boom.
Don't get wound up about Monel, or SS rivets, & exotic sealers. Coat things with marine silicone, & pull regular AL rivets. The forces hold the part together, the rivets just keep it there when the mast is down, silicone will seal it just fine. I have just coated the rivets on several Nacra masts, along with the joints at head, & base, with marine silicon. The masts float, & because there is no air exchange, there is no condensation. Using this simple, & cheap method, I experience a "whoosh" when drilling out a rivet on warm day.[/quote]
