From the drawing board to finished product we have robust procedures to check and verify boat quality every step of the way. Our gruelling marathon of 232 tests includes many sophisticated procedures normally associated with much larger yachts and ships. We perform sea trials in storms up to gale force eight, with waves as high as four metres, so we know the boats are solid enough to get you back should you be caught offshore. You can feel safe, reassured and relaxed aboard a Sealine.
