At low revs, it reduced our speed from 3.5 knots to 2 knots. exerting 28kg on the line. Flat out, it reduced the boat speed from 7 to 4.5 knots, exerting 100kg on the line. It set immediately on immersion despite the lack of any stiffening to hold the mouth of the cone open, and behaved well underwater, with no spinning, slewing or porpoising. A short length of chain helped keep it submerged. It was simple to recover, and a tripline will help to collapse the drogue on recovery" PBO, July 2014
Yacht drogues are designed to be towed from the stern during adverse weather conditions, helping to maintain course downwind and avoid broaching.
Yacht Drogues are normally deployed from the stern, attached via an Octoplait V shaped Bridle.
The bridle shares the shock load and can also be used to adjust the steering angle to the wave pattern.
Attach the bridle to a long warp to prevent shock loading and to ensure that the drogue remains submerged.
Smaller sized drogues can be trailed one behind the other on the same warp by making them off at different points along the rode using the stainless ring.
Jimmy Green Yacht Drogues also feature a webbing loop at the narrow end of the cone for trip line attachment.
Yacht Drogue Warp and Chain
The set up for each yacht drogue will depend on the expectation for slowing drift and the anticipated conditions in which it may be deployed.
The main principles are:
Jimmy Green Swivel Advisory
A swivel is optional.
Opinions are polarised on whether one is required.
Research into the subject is advisable, so that you can decide who or what to believe.
Practising deployment is also advisable - you can try without a swivel and see if it performs for your individual yacht and set up.
It is a simple enough task to add a swivel if you find that one is required.
Do you need a swivel ?
This largely depends on whether you believe that incorporating a swivel is a help or a hindrance in other yachting applications.
Do you think that a swivel encourages or prevents rotation ?
Generally speaking there are two possible scenarios:
The Jimmy Green Yacht Drogue Size roughly equates to yacht length in metres.
However, this is only a guide and will depend on your individual requirements.
|Drogue||Yacht Length||Mouth Ø||Exit Ø||Length|
|Size 6||6 metres||30cm||8cm||47cm|
|Size 8||8 metres||38cm||9cm||61cm|
|Size 10||10 metres||50cm||10cm||80cm|
|Size 12||12 metres||59cm||12cm||97cm|
|Size 14||14 metres||72cm||12cm||125cm|
Due to the complex nature of the sewing process, all the dimensions are approximate.
Exit Ø = the approximate diameter of the smaller end of the drogue
