Summary Analysis of the Design Ratios for the Oyster 39

1. The Sail Area/Displacement Ratio of the Oyster 39 is not published; hence we are unable to comment on this aspect of the yacht's performance.

2. A Ballast/Displacement Ratio of 40.1 means that the Oyster 39 should stand up well to her canvas in a blow, helping her to power through the waves.

3. A Displacement/Length Ratio of 235, tells us the Oyster 39 is a moderate displacement cruiser, which means she'll carry all your cruising gear without it having a dramatic effect on her performance. Most of today's sailboats intended for offshore cruising fall into this displacement category.

4. Ted Brewer's Comfort Ratio of 28.2 suggests that crew comfort of a Oyster 39 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 (CSF) of 1.9 tells us that a Oyster 39 would be a safer choice of sailboat for an ocean passage than one with a CSF of more than 2.0.
