1. Sail Area/Displacement Ratio: 9.7
2. Ballast/Displacement Ratio: 40.9
3. Displacement/Length Ratio: 494
4. Comfort Ratio: 54.6
5. Capsize Screening Formula: 1.3
1. A Sail Area/Displacement Ratio of just 9.7 suggests that the Vertue 25 will need a stiff breeze to get her going. In light conditions, unless you've got plenty of time on your hands, motor-sailing may be the way to go.
2. A Ballast/Displacement Ratio of 40.9 means that the Vertue 25 will stand up well to her canvas in a blow, helping her to power through the waves.
3. A Displacement/Length Ratio of 494, tells us the Vertue 25 is firmly in the ultra-heavy displacement category. Load her up as much as you like and her performance will be hardly affected, not that it was ever startling. Few if any sailboats are built to this displacement category these days - but they remain popular with some long-distance sailors.
4. Ted Brewer's Comfort Ratio of 54.6 suggests that crew comfort of a Vertue 25 in a seaway is similar to what you would associate with the motion of an extremely heavy bluewater boat - and that's as comfortable as life ever gets on a sailing boat!
5. The Capsize Screening Formula (CSF) of 1.3 indicates that a Vertue 25 would be a safer choice of sailboat for an ocean passage than one with a CSF of more than 2.0.
What is the history of Vertue 25 sailboat?
The history of the Vertue 25 sailboat is quite fascinating. It dates back to 1936, when the first boat of this design, named ANDRILLOT, was launched by Jack Laurent Giles for Humphrey Barton. The design was not named Vertue until after the war, when another boat of this design, named EPENETA, won the Little Ship Club's Vertue Cup in 1939 for a passage across the Bay of Biscay. The Vertue Cup is given for the best log of a cruise longer than a week by a member of the club.
The Vertue 25 sailboat gained an enviable reputation as a long-distance cruiser, with several remarkable voyages completed by boats of this class and close derivatives, such as Vertue XXXV, which sailed from England to New York in 1950. The design has also been praised by famous sailors such as Eric and Susan Hiscock.
There have been minor variants of the design, most notably in the shape of the coach-roof and the hull material. The original design had a length overall of 25'3" (7.7m), a beam of 7'2" (2.2m) and a draft of 4'6" (1.4m). The extended cruising version of the design was known as the Vertue Ocean and incorporated modifications suggested by Barton. The Vertue II design is slightly larger at 25'8" (7.8m) overall with a 7'10" (2.4m) beam and has been produced in GRP since the 1970s by Bossoms Boatyard in Oxford.
