TOPCAT hulls are made in Italy by hand. Each hull is equipped with a foam core and thus unsinkable.Inside the hull is a storage compartment that can be reached through the inspection hatch.Anti-slip strips on the deck of the hull provide support and prevent slippage during sailing.As standard, the hull is white with a red T along the hull. Material: GRP (polyester) There are the following different production types: 1. Hull type Standard: The standard hull is designed for the perfect balance between stability, performance and the least possible weight.Stable and durable, but without additional reinforcements, this type of hull is preferred by private customers and regatta sailors. 2. Hull type keel shoes: In these hulls, our famous keel shoe was attached to standard hulls already at the shipyard over the entire length of the keel.This makes it possible without damage to pull the boat over gravel. 3. Hull type reinforced and keel shoes: In these hulls we attach the greatest importance to robustness and stability.Equipped with keel shoes, an extra layer of fiberglass and special reinforcements at all critical points. This type of hull is particularly useful in sailing schools and hotels. Optically not to be differentiated from the other types of hulls, it is ready for heavy duty inside.
