A few weeks ago, we’ve explained here the SA/D ratio. Another ratio is also commonly used to compare the efficiency and power of cruising yachts: it’s the DLR or D/L ratio. It is a pretty good indicator of the “sea motion” for a yacht, since it will figure how a hull will behave in/on the …

The principle is quite basic: the more sail area we have, the more power we get. This wind’s energy is used to move the boat’s weight. The lighter the boat is, the more responsive she will be in after tacking, in accelerations, and of course in her capacity to reach high speeds with a given …

Among the factors contributing to the comfort at sea, you will find the bridgedeck clearance. Why? Because this height above the water, depending on its importance, will increase the seaworthiness. Just like the hull thinness, this height will prevent the boat from slamming on waves. When waves are slamming under, not only it’s unpleasant to …
