Safety is a key question that often comes up in discussions that we have with customers, and is of course a key focus in the development of the Candela model range.&lt;p&gt;As you mention, the deep V hull cuts waves pretty well, but we also have algorithms monitoring the position of the boat in 3D space, looking for signals that indicate a treacherous seastate or an unfavorable position of the boat. This means that we won&amp;#x27;t do the nose dives that you see in the sailing videos.&lt;p&gt;Be sure that we have landed unexpectedly quite a few times to get to where we are! :D&lt;p&gt;To sum it up, when you are accustomed to flying with the Seven and you know where the limits are in terms of wave handling, then it&amp;#x27;s no different from riding in a regular boat in choppy seas or high waves. Unruly seas require alert sailors, in all types of boats.&lt;p&gt;We&amp;#x27;re publishing a short video soon, purely focused on running through waves from large passenger ferries. Sub to our youtube to know when.</text></comment>

Control problems are all well solved for motorboats, but the moment of a sail that is perpendicular to the direction of travel puts a huge kink in the picture that has been hard to tame. Even then, there have been huge strides lately...like the iFly 15, which uses a mechanical active controller which basically relies on two small rods with a float on the ends to measure foiling height and heeling, and mechanically adjust the coils to maintain stability. It works marvellously.</text></comment>
