Hull Vane BV has developed a semi-custom, below-the-transom Hull Vane wing for recreational yachts of 10 to 20m (33 to 66ft.) Until now, the Hull Vane went only on commercial vessels and large yachts. But the company says it has developed a semi-custom version that works equally well on smaller yachts, improving their speed efficiency, extending their range, delivering a quieter ride and less fuel use. The semi-custom version was launched at the 2019 HISWA-in-Water Boat Show in early September in the Netherlands by Hull Vane BV.
