[Rhodes22-list] Anchoring

[ROGER PIHLAJA]

Mitch,

I've never had to remove my bow line chocks.  So, just for snicks and grins, this afternoon, I pulled one of the fasteners to see how the factory attached them.  The fastener was a stainless steel 1/4" flat head X 2" long wood screw.  The screw was bedded in some sort of caulk and the toe rail is solid FRP.  When I reinstalled the screw, I used Boat Life Seal polyurethane/silicone sealant.  This bow line chock is loaded in compression and shear, not tension.  The wood screw is not likely to ever pull out.

Mitch,

Yes, you can just screw the chocks into the toe rail, but don't use 5200.  5200 is a 'forever' adhesive.  There a very few places that I would say it's use is appropriate, and this is certainly _not_ one.  The screws will do the work of holding the chocks in place.

Since you'd just be screwing into fiberglass, I'd argue that even a sealant isn't really necessary. But if you decide to use one, get one from a marine supply store, not a home store.

I'd be a little generous in sizing the pilot hole for the screws.  You don't want to risk having the screws acting like wedges, and potentially splitting the toe-rail.

The message about using a tap was referring to the option of drilling holes, then tapping threads, and using bolts rather than screws.  On my boat, this approach was used for jib sheet tracks and winches.  If you don't have experience tapping threads, I'd stick to wood screws.  Hopefully, it goes without saying that the screws should be stainless steel.
