6.6 Sea Anchor
Deployed from the Bow
Back
Forward Index
The foregoing
recommendations and discussion apply to a drogue deployed from the stern
rather than a sea anchor deployed from the bow. A large sea anchor would
be required to hold the bow of a modern yacht into the wind and sea in a
survival storm. The required diameter of the cone or chute would be 2 or 3
times the diameter shown on Figure 25. The design load would be 50 to 100%
greater than that shown on Figure 26. Even with a large sea anchor the bow
of a modern yacht will tend to yaw away from the wind when the towline
goes slack as it will when the boat passes through the trough of the wave.
For these reasons the use of a sea anchor deployed from the bow is not
recommended.
