Swing Keel.

- A while ago, I wrote on this Tanton's Blog about keels called Keel, keel, and keels. (3/10/15. A modest overview over the appendage fitted to sailboats to achieve stability, direction and to fight going sideways.

- I will leave the centreboard for cruising boats aside for a while. Very popular in France, built by a few shipyards and in aluminum, the model is known as "deriveur integral". True centreboarder often ballasted, the raised board is totally integrated within the shape of the hull.

- The Swing keel is always outside the body, in a retracted or extended position, whether up or down and with only its articulation inside the hull. The keel shape results in a high aspect ratio foil.
