Sorry Luiz I reckon any bow protector needs to look part of the boat and not mark the skipper as a novice. I'm thinking of putting just a rubber strip on the bow painted the same as the boat to be unobtrusive but if someone has a better idea.
Great to see you've been flushed out and back online again by abuse of your thread RG. Cant wait to see the article and see if it generates some more activity, I don't want to upset the 420's because we may sink them with a below the waterline shot but then I'm the clubs repairer. My biggest concern is kids swimming, with a 420 not a problem, with the F12 the bow is on the waterline and would crack a skull at very low speed.
