I think one of Ronalds problems is just the place where he sails with breakwaters placed very closely together.
When sailing alone I'm guessing a design without boards might be the easiest to get thru the surf.
As far as I know that is the only place along the coast that has that problem, in places like Hoek van Holland the breakwaters have been submerged and replaced by the
Sand-Engine (expensive coastal infrastructural project, for the geeks among us).
