DVDesign 14m (38′) Rescue RIB

DVD-MANA-Layout

Here is another concept study, this time for a Coastguard unit which counts the busy and challenging Cook Straits as it’s operational area. They currently have a 14.5m vessel which is really getting long in the tooth and operates in displacement mode so covering the Straits is slow going indeed. In regard to finding their “next” vessel we have produced a 14m vessel as shown in the following concept sketches.

Principle feature of this vessel is the need to carry a decent sized tender on the aft deck. Additionally there is a service bay for stretchered patients etc. which does not encroach into the wheelhouse area and thereby hinder the operation of the vessel. This medical bay, being in the after part of the vessel and very close to the centre of pitching will be as comfortable as possible for survivors rescued from whatever their predicament might be.

Like the smaller 11.5m Rescue RIB this one also features a well-appointed bridge or wheelhouse (command station), with shock mitigating seating for 5 crewmembers. There is a dedicated chart table in addition to the usual helm and communications areas forward in the bridge. Being 14m in length the forward lower cabin area is big enough for galley, heads and crew quarters. Not shown but quite possible would be an upper tier of bunks in the forward cabin, bringing the total to be housed there to 4.

As mentioned before after part of the vessel is all cockpit, with enough length to carry a proper tender of over 3.5m. As this station gets involved in many towing operations there is a dedicated A-Frame towpost on this little ship with towline on a reel mounted on the deck. Still under discussion is ability to place crewmembers high up at observation posts above and behind the house structure. Presently there is space for one crewmember on each side but we are working on a platform to span the vessel and able to accommodate several crewmembers.

Whilst not a “de-rigueur” requirement this vessel will come close to self-righting capability due to the volume of the house structure. Draft restrictions caused by a bar entrance to Porirua Harbour mean that this vessel will most likely be jet driven, a practical and safe method of propulsion particularly with people

in the water. There’s not much more to say as we are still in negotiation in regard to proceeding with this project.
