Lazy jack for WR17

If you're using sail slugs, then lazy jacks can be very helpful. If you're not using sail slugs, maybe you can provide details on your expectations as to what they'll do for you.

I put adjusters on my lazy jacks. Once I had them set the way I wanted, I never needed to adjust them, so the adjustment feature really wasn't necessary. I also had a separate topping lift. Some people integrate the lazy jacks and topping lift into what some people call lazy lifts.

I found that if I was keeping the boat set up for the season, lazy jacks were worthwhile. If I'm daysailing, I find a topping lift is a huge benefit, but the lazy jacks aren't. I just use a bungy to wrap around the sail and boom when the sail is down. Keep in mind that I use sail slugs, so when the sail comes down, the slugs are held in the mast by a sail stop.

I used lazy jacks for years, and I would definitely install a topping lift. The TL makes everything associated with raising and lowering the main easier, plus turns the boom into a "safety bar" when clipped to the shroud when you are at anchor. You can then use the boom to steady yourself when moving around the boat.
The best way I found was to run the line through a block that attached to a bail at the top of the mast. The bail ran through an extra-long pin that replaced the regular pin in the halyard sheave.
I gave up on the lazy jacks because the flaked sail on the boom was still a bit of a bulky mess when I tried to stow it in the cockpit. I have switched over to furling the main around the boom as others have described, which makes the for a much neater bundle, is faster for me, is easier to stow, and does a better job aligning the bolt rope into the mast track when raising the main. I would never go back!
