2:1 Main Halyard

 Thirty years ago, when I had a Stiletto 27, I switched from a wire/rope halyard to a 2:1 high modulous line halyard. Part of the reason was a wonky shoulder, the same one that is flaring up now. Both the Stiletto and my current F-24 MK1 have bolt rope-in-slot luffs, which can be high friction for the size of the sail. It's a new sail and moves as smoothly as any I have seen, so that is not the problem. 

I'm not sure how much clearance there is between the fully hoisted sail and the masthead. Some, because it tension well with a winch. But I need to hoist and probably look from down the dock with a spotting scope.

 These  images give me an idea of the other clearances.

  • There seems to be enough fore-aft offset  between the pulley pin and the pin the topping lift is secured to for the dead end of the 2:1 halyard. My blue ladder is hanging from the main halyard (red), so it looks to be a good 1.5 inches forward of the pin. If I knot the halyard to the pin, the knot will not contact the sheave attached to the head of the sail. But I will need a low-profile sheave stack. I might just lash a large LFR to the head grommet, pretty slippery with Dyneema, low profile, light, and no chafe points.
  • There are some sharp spots cause by a shackle hitting the masthead I should do something with. But they have not chafed my current halyard, so probably not a big problem. 

 





 I'm thinking 8 mm NER Viper with a stripped (about 6 mm) last 25-30 feet is the proper rope. The current halyard is10 mm polyester DB.

Hero Life Jackets

 Yeah, I know it is PFD in the us.

 

I very nearly never wear a PFD sailing. It's hard to fall off a multi-hull and it's easy to rig jacklines and tethers that will keep you inside the lifelines. 

Whitewater kayaking, or open water paddling, yes. Beach cat and dinghy sailing, yes. But I don't wear the common inflatables. I wear either a whitewater-specific PFD or a Hero Waterwear inflatable. What you do not want is:

  • Auto-inflatable. If it inflates while you are under the boat you will not be able to swim out. This has happened too many times. They also snag on everything when inflated.
  • A jacket with gadgets attached. A light. A PLB. A radio. They will snag on ropes, and much worse, lines when the boat flips. You want something clean and simple, with no snag points.

 I was asked to test a HERO some years ago, and it has become a favorite. It's comfortable, better than a fixed PFD. Unlike an inflatable, it is not a snag machine when inflated. In fact, it is the smoothest, least snag-prone jacket I have ever found. It is just as effective (turning and flotaion) as standard inflatable PFDs.

 

Not in the way paddling. 
 
Pops you right up, even if starting with an intentional inverted kayak capsize. It contains some foam, so it can be worn on manual and will still provide some flotation.
 
Easy to deflate.  Standard oral inflation, backed up by foam, should you go in more than once in a day (which kayaking and dinghy racing are not that unlikely).

 My one recommendation is to pre-wet it on really hot days. The cooling effect is very nice.
