HULL DESIGN
Efficient performance and sea-keeping comfort are ensured by a hull theory rooted back in the office of Jack Hargrave. A round bilged forward bottom, transitioning to a chine aft, with a deep spray step in the hull side to keep the green water and spray where it belongs. The yacht parts the water with the fine and rounded forward sections. Then the bilge runs aft and transitions to a chine to provide lift and roll damping. Jack Hargrave developed this idea with the Burger yachts in 1960.
Hull Design
It is a dual purpose shape, burning little fuel underway, but offering a very stable yacht underway and at anchor. Mark Fitzgerald has done much research on the shape through computer hull modeling and digital testing. As a result, Adagio performs superbly in a broad range of sea conditions.
The modest draft of just 1.6m (5’3”) is very reasonable given the presence of a full-length keel to reduce damage in the event of grounding. Welded high-strength aluminium construction makes for impressive strength and moderate weight to strength ratio. This increases the yacht’s efficiency and maximizes the useable range and speed.
Cruising speeds of 8.0 to 10.0 knots are continuously achieved in all but heavy going, giving a range of 2000nm at 10 knots with the flexible auxiliary fuel tanks deployed the range is increased to 2540nm at 10 knots; large rudders and the Kobelt steering gear give good directional control.
