Open each challenge to see how it shows up on the water.
Constant UV exposure causes fading and surface degradation.
Saltwater corrosion and mineral build-up are harder to clean than road grime.
Boat surfaces are larger, curved and often textured: non-slip decks, uneven fiberglass.
Regular cleaning and polishing is time-consuming and physically demanding.
Existing products don't protect against saltwater corrosion, mineral build-up and the stubborn stains unique to marine vessels.

“My boat looks older than it is.”
Fading paint and yellowing gelcoat from constant sun.

“I spend more time cleaning than enjoying it.”
Salt spray, water spots and stains return after every outing.

“Heat and glare make time on board uncomfortable.”
Cabins get hot and glass glares on the water.
