Hi. Are you still working on a downhaul system, I also sail a Viking 22....Great
The system that I use for a headsail downhaul is simple and works well. I fasten a light line to the third hank from the top. This pulls the headsail down just below the spinnaker
during the downwind and is also reasonable for minimal windage while docking
The line goes straight down to a twisted clevis at the tack. (Going through more than one hank will bind.) The line is guided through the centre of my bow deck cleat, through a loose guide at the mast step and then cleated on the upper deck.
Prior to lowering the headsail I luff-up and use a short boat hook to grab the headsail sheet and pull the foot of the sail tight against the mast and cleat the sheet. Dousing the halyard and downhauling keeps the sail lowered and centred on deck if it is windy.
I did try using the downhaul through a centre hank to bring the clew in but gave up due to awkwardness, binding and windage issues.
The Gerr Downhaul that was suggested looks very interesting as it uses the two loose rings to allow a kind of "jackstay" on either side of the sail to keep it centred. I would imagine it would work well in light to medium air although may cause excessive windage and possibly wrap dangerously around the forestay if the wind
As far as overpowering the V22 I have found the following so far:
- Headsail only - can work - more difficult to point.
only - can work - more difficult to tack.
- Full Genoa
up to 15kts..18kts max - the main flogs.
/ reefed main can work 16kts to 22kts.
- Jib and full main work well 12kts to about 24kts.
- Jib and reefed main 24kts-30kts is exhilarating!
- Over 30kts - Read Gary Jobson!
Hope this helps a little...Good Luck!
