Re: series drogue or para anchor?
The biggest issue with a sea anchor would seem to be the many variables in getting it set and working as it should. Getting it positioned in the right wave set, getting a snatch block to sit in the right place to keep the boat quartered, just getting it over the side without fouling in heavy weather would be a challenge. The deployment of a sea anchor presents many more potential problems than a drogue. Also, being that this is not a routine procedure means that you will not practice using a sea anchor to the extent whereby you really feel confident in the procedure. I have a laminated sheet of deployment procedure right in the bag with it :
Deploy Sea Anchor
Check weather, ready all below decks before storm.
Link lines, sea anchor.
Buoy on trip line.
Put snatch block on pennant line.
Chafe gear ready.
All up to cockpit.
Up on deck clipped in.
Wrap pennant on winch to length, cleat.
To bow on windward side, bring :
Bitter end- cleat on 2 cleats (outside lifelines).
Tie off at approx. half the line (150')
Back to Cockpit
Ready main rig to go over.
Rode ready to uncoil freely.
Trip line/float unclipped and free to pull chute.
Launch over rail to windward. Wait for chute.
To bow with snatch block and pennant chafe gear.
Snatch block on anchor line
Set chute in 2nd wave crest.
Chafe gear on rode.
Adjust pennant, sails, and rudder to stay in slick.
Check hourly, adjust periodically to avoid chafe.
Probably the most important part of this is in doing it well before conditions get too bad.
I have also sewn up a seat belt drogue which I have yet to try.
