The Oyster 625, a centre-cockpit sloop, was designed by Rob Humphreys and built in the UK by Oyster Marine Ltd.
1. Sail Area/Displacement Ratio: 23.2
2. Ballast/Displacement Ratio: Not published
3. Displacement/Length Ratio: 182
4. Comfort Ratio: 41.9
5. Capsize Screening Formula: 1.7
1. A Sail Area/Displacement Ratio of 23.2 suggests that, in the right hands, the Oyster 625 will have enough performance to leave most other sailboats of similar waterline length well astern.
2. The Ballast/Displacement Ratio of the Oyster 625 has not been published, hence we are unable to comment on this aspect of its stiffness however as much of the ballast is concentrated in a bulb at the foot of her keel, she's likely stand up well to her canvas.
3. A Displacement/Length Ratio of 182, tells us the Oyster 625 is clearly a light displacement sailboat. If she's loaded with too much heavy cruising gear her performance will suffer to a degree.
4. Ted Brewer's Comfort Ratio of 41.9 suggests that crew comfort of an Oyster 625 in a seaway is similar to what you would associate with the motion of a heavy bluewater cruising boat. Pitching and rolling will be well damped - your cup of coffee on the salon table stands a reasonable chance of staying there in most conditions.
5. The Capsize Screening Formula (CSF) of 1.7 tells us that an Oyster 625 would be a safer choice of sailboat for an ocean passage than one with a CSF of more than 2.0.
