Lap-Stop
Lap-Stop is a floating wave attenuator designed for yachts and motorboats up to 50 feet, created to reduce the annoying lapping noise that can disturb a night onboard at anchor or on a mooring. Positioned at the bow, it works by flattening wind chop before it hits the hull, helping create a calmer zone around the front of the boat and improving comfort for those sleeping in the v-berth or forward cabin.

Designed by boaties who understand the problem firsthand, Lap-Stop offers a simple, practical solution to an age-old onboard annoyance. It is built from durable marine-grade inflatable material, requires no permanent fittings, and packs away neatly when not in use.
