These YKK SNADs are the best thing since sliced bread... I have 13 Robship's rope bags and winch handle holders attached in the cockpit now, I calculated that the SNADs save me from having to drill 56 holes in the fiberglass/gelcoat for mounting screws... I hope they last... I ordered a bunch of spares in case a few of them fail. 
(And follow-up message: update on the SNADS: I had zero problems with SNADs, not a single one came off but I made sure to wipe off the fiberglass/gelcoat underneath them with Isopropyl alcohol 91% before installing them.)
From Robship: What a beautiful boat... And thank-you for the chance to make these custom size bags in addition to the standard bags you ordered!
