The Fin Chaser Boats Dual flooding ballast system revolutionizes the traditional flooding keel system. You can trust that when you pull up to your favorite fishing spot the flooding keel will fill up automatically, lowering the center of gravity and putting more of the hull in the water resulting in ultimate stability at rest. Before you drive home you then have the option of filling up the forward ballast chamber, this is done by opening the gate valve pictured, a few minutes before you leave letting water rush from the already full ballast chamber to the forward ballast tank. The extra 100 – 200L (depending on model) of water up the front of the boat helps push the nose into chop and smooths out the ride for everyone on board. Both chambers breathe independently and can be flushed by placing a hose into the breather at the front of the boat ensuring salt residue is flushed away.
