While reading rec.boats.cruising, I noticed ray lunder
felt compelled to write:

Is there a general guideline for drogue size? My boat is 23', 9' beam,
tumbleholm stern, about 2.5 tons. Also, some boats have a provision
for chaining the rudder (mine doesn't) to avoid being bent by a
following wave. I assume the drogue is deployed on a line whose length
is somehow related to wave height or interval? Can you elaborate on
this? How do you avoid having the cockpit filled with seawater? Thank
you.

the other designers notes and research data on this site will answer
all the above.

The best $20 bucks you will ever spend. Cuts right through all the BS
you'll here from people who have 45 years and 100s of thousands of
miles "experience." For example, the cat owner in this earlier
discussion.
