Re: Johnstonís report on GGR and drouges
Morgan’s Cloud is a proponent of the JSD. They did a write up on why Suzzies drouge failed.
I think that for most of us their approach is over the top, and I’ve had that discussion on their site.
I’ve never used a drogue so I’m an armchair expert but here is my understanding.
A “normal” drogue is designed to slow one down, somewhere between 2/3 knots and 6/7 knots. A JSD provides significantly more resistance. Some recommend having a drogue AND a JSD so you can step up your resistance as conditions get worse.
I’ll describe what I have, not because I planned it but because it’s the way things evolved.
1. 300’ of 7/8” double braid
2. 600’ of 7/8” double braid
3. A Galerider
4. A Sea Break
The way I see it is I can progressively increase resistance like this.
1. 300’ bight
2. Add the 600’ in a bight
3. Reel in the 600’ and add a drogue to it
4. Reel in the 300’ and add a drogue to it
5. I have a small hank on head sail for my inner stay, not 2 sq meter, but we are 40,000 lb.
What I like about this approach is that the line has multiple uses, I could anchor in 400’ of water if needed if I added this line to my normal rode.
The drogues can serve multiple purposes. This year we were pitching badly at anchor one night, I deployed the Sea Break off the stern and it calmed things noticeably. Would probably help with roll also.
I met a gentleman who lost his boat, got pooped and lost his engine. His analysis is that he had the drogue out too early, it slowed him too much which encouraged the pooping. That kind of goes along with the idea of keeping some headsail up and sufficient speed for steerage.
Just my ruminating. Food for thought and comment.
