The Lavika Deluxe Boat Sponge in black and orange is a unique accessory for your boat. This highly absorbent synthetic sponge is 2 sided. One side makes it easy to lift out water and sand from the hull, and the other side has a mesh surface for scrubbing. It has an ergonomic shape for a comfortable hold and the snap-on strap attaches to your boat so it wont get lost or go overboard. This mildew-resistant sponge is machine washable.
