1. Sail Area/Displacement Ratio: Not published

1. The Sail Area/Displacement Ratio of the Westerly Ocean 49 is not publicly available. If you know differently, please contact us.
2. A Ballast/Displacement Ratio of 40.0 means that the Westerly Ocean 49 will initially stand up reasonably well to her canvas in a moderate breeze, but she'll need a reef in the main to avoid heeling excessively in a gust.
3. A Displacement/Length Ratio of 173, tells us the Westerly Ocean 49 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 27.4 suggests that crew comfort of a Westerly Ocean 49 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 2.0 indicates that a Westerly Ocean 49 would not be the wisest choice of sailboat for ocean passage-making owing to the lower resistance to capsize in strong winds and heavy seas that is associated with sailboats with a CSF of 2.0 and above.

'Endeavour' is a very special Tartan 34C, as you will see from the cutter rig modification, Ratcliffe wind vane auxiliary rudder self-steering, SSB radio, radar, and more.

The broad beam, large cockpit and spacious salon of the Dudley Dix Hout Bay 40 make for a very comfortable sailboat to live aboard and sail.
