gray duck Posted July 9, 2021 Report Share Posted July 9, 2021 Are people still using "Keel Ropes" as a relatively cheap and easy sacrificial keel guard? For those that have used them and liked them, what type of rope is the best to use? I'm using west system epoxy and the hull is okume S&G. thanks!

PeterP Posted July 9, 2021 Report Share Posted July 9, 2021 I have used it on rudder tips and center boards. I don't see why it would not work on small boat keels. I use any old line that's not good enough for first line work on a sail boat anymore. My favorite is a double braid dacron. Soaks up epoxy well and when scuffed in grounding the fuzz can be slicked down quickly. Stay away from kevlar if you can. Impossible to finish slick. Good luck PeterP Quote Link to comment Share on other sites More sharing options...
Paul356 Posted July 9, 2021 Report Share Posted July 9, 2021 Very similar to Peter's comments. I used some double braid dacron. I routed a groove in the leading edge, tho not too deep. Maybe a half or quarter of the rope depth? I don't quite remember. Then I coated the groove with epoxy and also soaked the line in neat epoxy before putting it into the groove, and made sure all the drips were caught, etc. I assume this would work on bow or keel; it certainly has worked on my centerboard and rudder.

gray duck Posted July 23, 2021 Author Report Share Posted July 23, 2021 thanks for the replies - seems to make more sense to me to put rope on top of the fiberglass ,cuz it is sacrificial Quote Link to comment Share on other sites More sharing options...

What ever you wear away does not expose wood, and you can fill it back in after the damage. Wraping glass around a nice round leading edge would be a lot easier to get fair. I would do the glass after. Quote Link to comment Share on other sites More sharing options...

I bet it does work, but I still wouldn't do it. A SS, Brass or Bronze chafe strip is even more durable and easy to replace waaaaaaaaay down the road when needed.

Paul356 Posted July 23, 2021 Report Share Posted July 23, 2021 I wont argue that, except I had a terrible time with my lightweight brass keel strip buckling as applied so wish I'd put something heavier on. Quote Link to comment Share on other sites More sharing options...
Oyster Posted July 24, 2021 Report Share Posted July 24, 2021 I have set the rope in thickened epoxy with a few small wire brad or tack thru the rope on the edge to temporarily hold it in place. Dry fit the length of the rope before starting the job of course. While wet just cover the rope with more thickened epoxy and then work a layer of biaxal glass covered by a layer of finish cloth or a couple or three layers of finish cloth tape over the edge and shape the round using the uncured thickened epoxy and glass. With the glass overlaying onto the board, you will not have a problem with the edge, or moisture in the end grain even if you rub the glass over sandy or oyster bottoms. Just keep tabs on the edge from time to time. If you use a good primer over the glass work that will be hidden like Interprotect 2000, this further creates a bullet proof arrangement.

Bending half round or half oval is tricky. Hollow is even trickier. It wants to kink. I bend my pieces over a mold before drilling holes. This helps a lot!! I bet a 3/4" flat stock would work well too. Just file the exposed corners a little after installing. https://www.mcmaster.com/bronze/easy-to-machine-architectural-385-brass-bars/ Quote Link to comment Share on other sites More sharing options...
