Description

This is the second in our range of patrol, rescue and fast passenger commuter vessels featuring the now distinctive and signature "Z bow" and are built to the limit of what a coxswain can legally drive. This boat features plenty of grab rails and the highly developed stepped hull geometry. The "Z bow" allows the builder/designer to fine up the vessel's entry to provide a smoother ride without sacrificing the necessary volume forward to ensure a safe ride and allows the boat to perform like a wide flat bottom vessel while still maintaining higher than average deadrise resulting in a soft fast efficient ride.

As with all our people moving vessels, the now distinctive and signature "Z bow" is designed for wave piercing to reduce vertical accelerations, adding to passenger comfort, and gives early gaining of boyancy when the bow dips in a following sea. 

The 33 pax version is a real winner for tour operators needing a fuel efficient, cheap to run vessel with a maximim of passengers whilst maintaining excellent cruise and top speeds.

These vessels feature outboard engines, again allowing operation by a coxswain but also allowing cost effective installation of dynamic positioning and joystick-based control systems and rapid replacement in the event of engine failure. Inboards options are of course available and depending on target speeds the vessels would work well with water jets. Either option would free up transom space for a large boarding platform, easier towing or perhaps carrying a small tender.

Along with the Z-bow, these vessels also utilise CTMD’s proven stepped hulls with large vents. Stepped hulls are not uncommon in this market place, however, they are often over simplified and as a result can cause in increase in drag at slow to moderate cruising speeds. Stepped hulls work by distributing the lift required to get a boat on the plane away from just the transom but to an area in front of each step as well. In order to do this air has to be able to get behind each of the steps or a vacuum will form effectively sucking the boat down onto the water and increasing it’s drag. On race boats or other high-speed vessel’s this is not a problem as the vessel is often close to airborne and as a result air can get behind the steps. On a passenger boat that spends much of its time at reduced “cruising speeds” this is not the case. By incorporating oversize vents in the side of the vessel at each step the CTMD stepped hulls are able to get air behind the steps even when operating in displacement mode. Thus resulting in more efficiency across a range of speeds.
