Summary Analysis of the Design Ratios for the Beneteau Oceanis 381

eBook: How to Avoid Buying the Wrong SailboatDownload this eBook to make sure you buy wisely!

1. A Sail Area/Displacement Ratio of 15.5 suggests that the Beneteau Oceanis 381 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 31.6 would usually mean that the Beneteau Oceanis 381 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 189, tells us the Beneteau Oceanis 381 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 22.2 suggests that crew comfort of a Beneteau Oceanis 381 in a seaway is similar to what you would associate with the motion of a coastal cruiser with moderate stability, which is not encouraging news for anyone prone to seasickness. 

5. The Capsize Screening Formula of 2.1 tells us that a Beneteau Oceanis 381 would not be as good a choice of sailboat for ocean passage-making, owing to the increased risk of capsize in strong winds and heavy seas when compared to a sailboat with a CSF of less than 2.0.
