The Elan E3 due to its lightness and hull design will be a really fast boat downwind but probably it will lose to the Hanse upwind on most circumstances. The Elan E3 is a very nice design and although it is a Class A sailboat, it has much less ballast than the Hanse, however it has a high performance keel that maximizes ballast even if I donвЂ™t believe that will be enough to give it a final stability and an AVS as good as the one on the Hanse.Д«esides the Hanse is substantially heavier, 4700 to 3690 Kg (being a big part of that weight difference in ballast) and that will give it an overall bigger stability, as if it was a bigger boat. The interior even if bigger is not so nice as the one on the Oceanis 30.1. The Hanse 315 it is a Class A sailboat, it is a very good sailboat and will have no problem offshore, unless on a real storm. Probably it sails very well downwind and poorly upwind with waves due to lack of power (low beam, low ballast). It is a Class B boat with a stability that will be enough to sail with good or reasonable weather but that makes it not suitable as a real offshore boat. The Oceanis 30.1 has a very nice interior and has a reduced beam that can allow it to be road transportable. Sorry to take so long to reply but I have little time now and it is a big question LOL. The foil that swings down has very little ballast and all is up on a relatively big box partially under the hull.Д«ecause the ballast CG is high, it needs a lot more ballast to have the same RM as a swing keel with all ballast on the keel. The one I think you are calling a lifting keel, the one on the middle on the drawings, it is not efficient and it makes the boat much heavier. That is a very efficient keel that needs however a big vertical box that on a small boat is impractical because it will occupy a lot of interior space.Д¬omparing with the swing keel with all ballast on the keel, it is hydrodynamically more efficient but has the disadvantage of being more fragile in what regards groundings, besides the big difference in what regards interior space requirements. What are the lifting keel you are talking about? Unless you are talking about the Oceanis Swallow draft version that uses a swing foil? That is not what is generally called a lifting keel.ДЄ lifting keel is normally a foil that can go up and down having at the bottom a lead torpedo with almost all ballast.
