It had grip tape on it many years ago, but not any longer. While I am looking forward to sailing it, chances are I will be sailing it 4 or 5 times a summer, so it isn’t going to get a lot of wear. I have SeaDek on the lid of a Yeti cooler and it has held up well. I highly doubt it will discolor over time as it is designed to be in the sun and the Sunfish will be protected when not in use. You’re correct, I will have to be careful about the boom and blocks.I've seen their teak and holly stuff on power boats a lot and it looks great. However it is fragile to some extent. I has a softness to it, that you definitely don't wear hard sole street shoes on it, but you'd never walk around on a Sunfish either. IOW, I don't think it can take much of a beating, without getting cuts and gashes in it....like having a boom lay on it and the mainsheet blocks scraping across it... stuff like that. If you're sliding around too much, you might consider strips of antiskid, but not sure what they'd do, if and when you peel them off. Lastly, I don't seem to see many ...or any? that actually do something like this as it hasn't seemed to be an issue. 6mm...that's close to a 1/4 inch, so realize you might catch the edges too. Most of the installs I've seen, edge protection hasn't been an issue. Like I said, looks great on the transom of a 40ft SeaRay, but all aboard are running around barefoot, I can bet ya.
Oh....one other thing, I imagine sitting on it a lot is going to eventually dis-color it to some extent. It's not as easy a surface to clean as gelcoat. I'm sure the manufacturer will scoff at everything I've said, but I've seen it a lot, usually put on boats where the owner has more money than experience and is "high" on making it look good. I don't see for the most part, the captain who has had his boat for 10 years, and finally deciding to put something like this down, to always be walking on it.
As a thought...if you're good with gelcoat or paint...put some anti-skid stuff in the paint and apply. If you don't like it, you can always sand it down and repaint or gelcoat.
I don’t think I need to go quite that far...yet!If you are really concerned about not being able to stay put, do what I do - I’m old and barely able to stay onboard myself, so I’ve installed both port and starboard seatbelts I salvaged out of my LeBaron convertible.
Obviously they added it for a reason. Restoring this boat is as much just a fun project as it is just to have a boat to go sailing every now and again. I thought the SeaDek might be a cool upgrade.Newer Sunfish have texture in the area outlined by River Time. Not sure when that started, but it's on my 2005 hull.
