I'm guessing the thin fences on the more aircraft-like (
Advanced Aerodynamic Vessels, SAS) would be frowned upon by boaters that might be looking at the Renaissance Prowler.
Factors such as durability of taking waves and acting as a hazard to swimmers/divers plus that fences just might not look "boat-like" enough could be factors.
And finally, fabrication of a boat hull is different than an aircraft like skin.
