The Oyster 62, a light displacement centre-cockpit cutter, was designed by Rob Humphreys and built in the UK by Oyster Marine Ltd.

1. Sail Area/Displacement Ratio: 19.5
2. Ballast/Displacement Ratio: 29.4
3. Displacement/Length Ratio: 188
4. Comfort Ratio: 41.2
5. Capsize Screening Formula: 1.7
1. A Sail Area/Displacement Ratio of 19.5 suggests that the Oyster 62 will, in the right conditions, approach her maximum hull speed readily and satisfy the sailing performance expectations of most cruising sailors.
2. A Ballast/Displacement Ratio of 29.5 would usually mean that the Oyster 62 would have a tendency to heel uncomfortably in a gust, and need to be reefed early to keep her sailing upright in a moderate breeze.
However, as she has much of her ballast concentrated in a bulb at the foot of her keel, she's likely to be considerably stiffer than her published Ballast/Displacement Ratio might suggest.
3. A Displacement/Length Ratio of 188, tells us the Oyster 62 is 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 41.2 suggests that crew comfort of an Oyster 62 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 62 would be a safer choice of sailboat for an ocean passage than one with a CSF of more than 2.0.
