Knot Supersonic is a 2006 DeFever 49 Cockpit Motor Yacht, commonly CPMY or CMY

The 49 CPMY is sometimes referred to as a 44 + 5 because it has the same basic layout as a DeFever 44 but with a 5-foot cockpit. The boat is very comfortable for living and cruising and, although it doesn’t get anywhere fast, it is very capable and can handle more than the owners can take.

The boat’s name, “Knot Supersonic,” and the F-14 Tomcat logo is a nod to our previous life as a military family and Will being a part of military aviation for 27 years.  As a military aviator flying the F-14 Tomcat in the Navy and the F-15 Eagle in the Air Force, flying supersonic was the standard. Since the Defever doesn’t get anywhere fast, Knot Supersonic seemed fitting.

Locking in the Defever 49 CPMY: Long story short, locks either have cables or pipe that the boat connects to with its own line or use the weighted lines that are attached to the top of the lock and then taken to the boat. As the boat rises or falls in the lock, the boater then adjusts the lines to stay close to the lock wall.

We have found that the middle hawsepipe with cleat enables excellent balance as the only connection to the cables, pipes or weighted lines. The captain then stays at the helm using differential power to keep the bow straight. We found that when both of us are on the deck with each taking a line, it is much more difficult to control the boat.
