DH550 Charter Catamaran

The DH550 catamaran has been or is being built in the Caribbean, Europe, Africa and Australia. All of these builds have been to the original design, as drawn for Phil and Laura Harvey to build the prototype "Wild Vanilla" as a family cruiser.

We now have a new version of the DH550 , named the DH550 Charter. It was commissioned by a charter company and construction will start in the next few weeks. It has features that are better suited to charter service, in the cabins, bridgedeck accommodations and rig.

This version has four equal double guest cabins, each with en-suite heads and shower. There is also a compact single crew cabin in the bows of each hull and a shared crew heads with shower in the starboard hull.

More space has been given over to life outside, so the bridgedeck accommodation has a smaller saloon and larger cockpit than the cruising version. It has two galleys, one internal and the other in the cockpit. The forward cockpit, a working area in the cruising version, is changed to a social area with seating and folding table. The working cockpit has moved aft to above the outside galley, with helm and engine controls. All sail control lines, except halliard and reefing lines, are led to a pair of electric winches mounted on the cabin roof. This cockpit has large cave lockers to keep the ropes tidy and out from underfoot.

The rig commissioned by my client has in-mast furling for easy handling. It has vertical battens to support modest roach.The boom has been raised for better clearance over the working cockpit. It has also been lengthened to regain some of the lost sail area and to move the sheet further aft to where it won't conflict with the working cockpit. A pair of posts has been added in the cockpit to pick up the loads applied to the cockpit roof by the mainsheet.

I also drew an alternative charter rig with slab reefing instead of in-mast furling. It regains area by means of more roach

Aesthetically, the charter and cruising versions are little different. The working cockpit is fairly inconspicuous, so doesn't spoil the clean lines of the cabin.

This version is only offered with cruising keels, for simplicity of operation. Lack of the daggerboard casings also gives more freedom for fitting in the required accommodation in the forward guest cabins.

The two steering stations are separate, connected only at the tillers on the rudder shafts, giving 100% redundancy. In the event of breaking a steering cable, the boat can still be steered at the other helm.
