Here is my attempt at a keel guard using 1/2″ wide aluminum flat stock mounted using 3M VHB (Very High Bond) Foam Tape. Hopefully it will work, somewhat, otherwise it’s back to the drawing board…
UPDATE 10/15/2017: It’s been 10 months now that I have been using this keel guard and it is still holding strong with no issues at all.
