Be careful not to lose the nylon bush mark 7.

Catamaran lifting keel. In fact a 11 AR is OK for keels although 21 or a bit more is better. - sets less gently due to U-shaped or trapezoidal section. That is why foils are curved because we want to lift to be directional which is behind the curve.

Catamarans typically have less hull volume smaller displacement and shallower draft than monohulls of comparable length. To solve this dilemma we elected to have a hydraulic lifting keel. The keel or daggerboard catamaran on the other hand can more efficiently create lift for the same keel plan view area not only because it has two vs.

Vertical lifting keels have loads on them and they are generally designed to be in the full up position or full down position with no load on them between those two points. The two hulls combined also often have a smaller. Meaning the boat is basically stopped while you lift the keel.

The daggerboards on most cats are way too small. I am with Richard Woods and we are talking about catamarans. The 10 ton lead bulb moves up and down so that the draft can be reduced to 6 feet 19m for access to shallow anchorages and the keel can be lowered to a draft of 11 feet 34m for high performance bluewater sailing.

The conclusion I came to was a simple one. Catana 40 S Cruising sailboat Catamaran Centerboarder Lifting keel Sloop cruising racing boats. I also believe that their short chords work against them not for them and mini-keels are no surprise worse still.

Pull out the all mechanism. In other words a 15m deep daggerboard on a 10m boat will be about 750mm foreaft or more properly called its chord. Cats only seem to get given small daggerboards.
