What are some of the Definitions used in the Power Catamaran Industry?
Tunnel All cats have one, although some are specifically called the tunnel hull. It’s the space between the two hulls and the underwing or bridge deck, and is relied upon for lift. Slamming (Called “pounding” on V-hulls) Occurs when a wave is trapped inside the tunnel and hits the underwing. A lightweight, good design, and sustained speeds prevent slamming. Sneezing Exclusive to cats, it’s a spray from the front of the tunnel back into the boat. Air compresses the water and creates a cushion. The air cannot escape out the back of the tunnel and thus is forced forward. Poor design and /or balance usually cause sneezing, and weight can sometimes be a factor. Thanks to our great hull design and attention to weight and balance, Twin Vee PowerCats are practically immune to sneezing. Banking (“Leaning” for some) The lateral attitude of a vessel, applicable to moving vehicles as well. V-hull boats, bicycles, and motorcycles bank into a turn. Powered catamarans on the other hand, are more simi
