I admit I could be wrong, it is only designed for thin string, so must be for a tripping line

I had an engine failure in my 24' Zodiac Hurricane in deep water about 600 miles south of Hawaii, and used a sea anchor overnight while I got some sleep. Seas were about 15' with a 20-25 knot wind, and only a slight current.

I used a 9' Para Tech sea anchor with a 15' length of chain mid catenary (a great help) and trip line with float for recovery. It's the only time I've deployed one except for testing, so I had (and have) very limited experience and am certainly not an authority.

I found it deployed easily over the side and "caught" and as soon as some pressure was taken on the line, immediately bringing the bow into the weather. I payed out the line about 200' and tied it off. It felt exactly like dropping anchor, and held out position with minimal drift. The angle of the anchor rode is more horizontal than when using ground takle, so burying the bow was not a problem.

Recovery was a bit tricky because it was impossible to haul in the line, which essentially means pulling the boat toward the sea anchor against the prevailing weather. It's handled just as if you were anchored to the bottom, powering forward while simultaneously taking in the line so it doesn't foul the prop. It took a while, and I wouldn't like to do it often in heavier weather or without a trip line, but I was able to bring it in without complications.

This web site has good information on the subject

Oh Dear!

I thought a cheap sea anchor would be an easy option to putting an auxiliary O/B on the boat. Seems sea Anchors are a science too.

Thanks for the thoughts.......

I think that you are right!!
Never said that you were wrong I was just saying that all the sea anchors have this short of eye thing for tripping them. That's all

Mike C,

Though I belive there is a science to sea anchors, I think the problem is that the information on the pack is rather limited. Mine detailed yachts and motor cruisers size so I estimated my need on a RIB.

A larger problem is that you don't go out in bad weather to test such equipment normally. When I have tried the wether was not very bad, it worked, but I don't have full confidence in the way it was set and the control of the snatch.

Hopefully it will be sorted soon
