Rene,

in that case, if you have a stout bucket on board, you could even use that one as a drogue. I suggest you try a bucket, just to see if it produces enough resistance.

Rene,

Now I have summed up the little I know about making a parachute drogue.

It is called «20180611 making a parachute drogue”. It is just a draft (ver. 20180612a), but hopefully it will soon be replaced with a proof-read version. Nevertheless, the diagram and photos should tell most of what you need to make one yourself.

Good luck!

Arne

PS: When the link dies, the file can still be found in ‘my’ JRA folder, under “How-To notes”.

PPS, 20180614: The final version has now been up-loaded (ver. 20180614a).

Hello Arne, some time back you mentionted a set of parachute drogues and a ball fender you want to use when raising or lowering sail.

I like the idea, 

I typically start sailing in narrow waters and it won’t be the first time i ended up too close to the shore.

Hope you have an update

Regards, Rene

[Webmaster: could we perhaps retitle this topic something like:"Discussion of Design and Use of Drogues", as we've drifted a long way away from the Seabrake?]

As always happens, thinking about something like this gets me wondering about whether there are any design improvements to be made to drogues.The main requirement, it seems to me, is to get an even drag, whatever the wave action. The JSD works, as a stopping drogue, but is laborious to make, and to recover once deployed (and is more powerful in its action than most people require, in less than extreme conditions). The JSD achieves this by putting a large number of cones into all parts of the circulation of water particles within the wave, and many people have wondered whether fewer, larger cones, spaced out in the same way, would be easier to make, deploy and recover. The Seaclaw achieves this by diving, and putting one drag-producing item deeper below the  waves. The Galerider works by creating turbulence as the water passes through a mesh, rather than producing hydrodynamic forces by acting upon a cone.

Could there be, I wonder, a single device (or a small number of devices daisy-chained together), made of mesh, designed so as to dive and thus needing less passive weight to get deeper into the water? I think so.

SNAP....I have stainless shackles on my halyard blocks too! With globslisation and the dubious grades of steel you have these days, it is hard to know what you are really getting. I threaded several loops of dynema on the anchor point between yard and halyard.  Once I get up the mast I will do the same at the mast cap. I think if I had a drogue, I'd back it up with dynema.
