VSV stands for Very Slender Vessel. Mary Slim sports a narrowed beam (4.2m) and long (22.5m) configuration. She is designed to pierce through waves and combine speed and distance into one hull.

Traditional hull designs are always challenge between speed and distance, and the choice between a displacement or planing hull as their guiding light. A displacement boat will give range but not speed, and a planing boat will give speed but lack range. Built by Multimarine Composites Limited the Very Slim Vessel attempts to fuse the best of both worlds … its long thin hull runs in displacement while it planes on the hull chines. the axe bow and hull design pierces the waves instead of riding on the surface, smoothing the ride and enabling it to travel quickly.

She can hold 3,170 gal of fuel with a range of 1800 miles. VSV cruising speed of 25 knots and a respectable top speed of 32 knots, making her one of the fastest long distance boat in the world. The builder is currently exploring a green alternative, using bio-diesel to power her.
