The Elan 400 is one of the more interesting new boats around. It has a very nice hull with a moderate beam for a 40ft, a transom that will make it easy to sail downwind, a great stability curve, not only in what regards sailing power but also in what regards AVS and reserve stability. Also a very good proportion between positive and negative stability. It has also a nice interior. They have now online a very good virtual visit:
Looking at the Polar speed we can see that this is a fast boat but not a boat that will plan easily and that is a pity. Looking at the boat and hull we can get that impression but a better look, specially in 3D will show that the hull is very rounded and deep. That will be great for comfort, but not good in what regards planing. The reasons are two, that moderated beam (that certainly will make it a good boat upwind) and the weight: 7500kg.
This is not an expensive boat and the building techniques are not top due to price management. It would be easy to make this boat with less 1000/1500kg for a higher price. That should be enough to change the Polar curve in what regards the wind needed to have it planing, that now is as high as 25/30k.
Don't take me wrong, this is a fast boat that will make almost 8K with 10K wind....but I am not even sure that it will be faster than a Salona 41 and looking at both boats this one looks a lot faster.
Not a match for a boat like the Opium 39 or the JPK 38, specially the last one that is one of the most interesting performance cruisers around.
