WHAT MAKES A DISCOVERY SHIPYARD YACHT DIFFERENT.
Keel for catamaran. How the keels were lost is a mystery as the owner was not aware of anything at the time. With the keel in place drill down from inside the boat. The Discovery shipyard build a range of highly capable blue water cruising yachts providing a safe platform on which to sail both crew and guests to the most remote and breathtaking waters of the world in comfort and style.
Swing Keel Lower Saloon. So even if both vessels are pointing at 45 degrees the monohull will be making a better track to windward. Your sails keels daggerboards and rudders when moving forward into the wind create high pressure of the windward side and low pressure on the leeward side and the boat is pulled forward into the wind.
This Robertson and Caine design is simply awesome. Abstractly this is why you can sail upwind. The advantages of catamarans are great resulting in fast speeds.
A monohull with a large keel lateral resistance makes less leeway than a catamaran with shallow keels. Daggerboards are typically a bit heavier. Buoyancy is carried down to the keel.
That is because to optimize speed you need a hull with buoyancy in the ends not in the middle technically you need a high Prismatic Coefficient - Cp. Catamarans sit on top of the water with much less keel area below the water and are much more affected by the wind. Catamarans with dagger boards are.
The original keels were built as a hollow. In an iron keel sistering is typically a matter of drilling and tapping the cast iron and threading in a new bolt. When the boat was lifted it was discovered that both keels were missing.
