As someone who had never heard of it, yes. But the site is really to attract people to the club and keep them informed, at least I assume that is its purpose. Since the island does appear to want to attract some tourism and visitors, it could be good for the people that come to visit.
Do most English and French already know where the island is? It seems that would be most of your visitors but I am just guessing. It certainly won't hurt the site to have a little info on the island.
Have fun, with the boats and the web site!
