Is the front and rear deck material the same material the boat is made of (Roplene)?
The sheet material used for floors, decks, and hatches is High Density Polyethylene(HDPE) that is extruded into sheet form and the boat is rotationally molded from Linear Low(med) Density(LDPE) Polyethylene. They have very similar properties in terms of strength and thermal expansion. The HDPE is a little stiffer but does not have quite as good impact strength.
