Hi all,

Would love to learn from those of you who have spent some time single-handing the 430.

To set the stage, I'm working with a six winch setup - two on the cabin roof (electric to starboard) and four aft in the cockpit. 

My last boat was an old Swedish Wasa 55 with a small cockpit so nothing was out of reach - though there were 'extra' jobs like running backstays.

When I use the natural cabin-top winches for the main and jib sheets, they feel far from the steering position. Anyone using those winches to run the sheets toward the winches closer to the steering position? 

I'm also struggling with halyards loosening (not related to single-handing) so it is tempting to keep them on the cabin top winches. 

Anyway - any experiences here will get a listen!

Well, I converted my mainsheet system to a "german" mainsheet system. It is double ended, each end goes down the mast to the fairleads on the cabin top, and then back to the big primary winches in the back of the boat, reachable by the helmsman. I also put a traveler system on, but you don't need to do that to lead the mainsheet back. I put sheet stoppers in front of the winches so you can unload the winches and use them for other things.

Then this season I electrified one of the aft winches because my wife's shoulder was bothering her.. ....

I've led (on my 371) the jib sheet to the starboard rear winches through 
(1) a block in the self tacker stand and
(2) a block in he barber hauler fastening just after the shrouds (custom added)

With this, I manage the self tacker form either of the rear starboard winched.

Maybe the attached pic helps to describe the set up: https://pbase.com/pekkal/image/163438494.jpg

Really appreciated! 

I think in the interim I can route the main and jib sheets around the cabin top winches toward the aft winches. Main sheet to starboard and jib to port. I'm curious if I can then keep the main halyard on the electric starboard cabin top winch as I do this though.. 

Another question: For some reason, I'm struggling to get the luff tight using just the clutch. Even after replacing the clutch cam with a 6-10mm (which just makes it hard work to drop the sail and has virtually no impact on the luff tension) it's still loose in the two meters above the boom. Driving me nuts :)

I am struggling a bit with the terminology & translations, so I may have misunderstood ... but anyhow: are you using a cunningham (downhaul)? 

I do not think there is any way to sheet the bottom of the mainsail luff tight without it, as it would assume perfect geometry regardless of boom angle & mast bend. 

I have routed the cunningham from a fastening at the bottom of the mast (where the kicker is attached) through an eye in sail the through block at the mast foot to the clutch, giving me 2:1 purchase ratio, which is enough for H371 ... and I do not want tear the sail.

Luff: The leading or front edge of a sail.Luff tension: force exerted along the luff (vertically) mainly by the halyard; and also cunningham if rigged.

Cunningham: Block and tackle used to adjust mainsail luff tension. Lower end is attached to the mast just above the deck. The upper end has a hook to attach to a ring just above about 15” (38cm) above the tack. The purchase ratio is commonly 4:1.

Hi Pekka, have not been using a cunningham - not currently rigged but a simple fix I suppose. 

You're correct on terms - this is luff tension. Weirdly - I feel like most of the slack in the luff is below the cunningham slot on the mainsail.

The eye for the cunningham in my main sail is maybe 30-40 cm from the main sail bottom. Tightening the cunningham produces of course a major wrinkle below the eye, but smooth sail above it. So instead of 2m loose main sail puff you should end up with a foot or so.
