sea anchors

Hi,

Does anyone have any experience with Sea Anchors? I never carried one with my old boat but now I only have one engine, (and still no backup yet), I think a sea anchor would be a good idea. (Just to keep my nose into the weather while I wait for rescue!)

They seem to come in 4 sizes, (probably more, but from the mail order catalogue I have there's 4). They are…..

65 x 75 cm
125 x 125 cm
135 x 142 cm
and
190 x 145 cm

Whilst I'm sure bigger is better, does anyone have any practical experience at what size will work OK for a ton or so of boat?
(Humber Ocean Pro 6.3 with Mercruiser 1.7 Tdi)

Thanks,

Mike C

Sea Anchor

Mike

I carry 2 sea anchors but have so far not had to use them, I think they are a good piece of safety equipment to carry.

Hi Mike

Do a search there was a post a few months ago about sea anchors, or it may have been under para anchors.

Regards Gary

I think you need the 65x75 mm.
I have the same size sea anchor on my boat (7mtr Falcon about 900 kgs weight with full gear onboard and 4 people). That size was recommended to me by the retailer after looking at his chart.
The bigger the better does not apply here I don't think.
The diameter of the sea anchor is related to the weight of the boat. There is a chart that shows what size anchor you use for weight of a boat and length of rope depending boat length.
However, to be on the safe side why don't you ask the chandler shop to tell you??

Thanks Manos,

I'll look at the other threads and try the chandlery... but they are a yachty one so may not know about their use on RIBs. I just thought someone might have a suggestion re size!

If you need to deploy it in rough weather, make sure it's fastened to something before you pull it out of the bag. or it might blow away !

On a side line
Some where I have a photo of Tiger sitting inside his sea anchor like a little tent.
I wonder how long before he calls me asking not to post

Sea Anchors

Have demonstrated their use on PB courses and used 8 ft dia parachute. slowed drift to 0.2 of a knot in about 20 knots of wind whilst accompanying boat drifted off at 1.9k. not a real test but illuminating.

Consider attaching to bow eye not over bow tube which would hold down bow - poss under breaking wave!!!! ( but then you have problem of adjusting - to suit wave length (the tension will be extreme!)

need to experiment with recovery technique. As you motor forward, chute may sink and you end up with a vertical lift!!! Big boats attach fender on floating line to parachute (15 -20 metres)in an arc and recover collapsed chute via fender.

fender obtained on ebay for about 15 two years ago. fwiw

Mine has a piont on the tail for a tripping line which makes recovery much easier.
