I've used them on a Bene 40.7 I used to race
on and my current
47' battle wagon and have to say that when i replace my mainsail
I'm going to lazy jacks.
The Bene had a relatively new mainsail
, my current
boat came with a main that is, to say the least, beyond it's prime and the Dutchman system didn't have any huge advantage over more traditional flaking systems I've had. It did have more disadvantages though, mounting the mainsail in the first place becomes a bigger pain than it needs to be. The chafe issues already mentioned and the "pucks" mounted to the sails
were another added maintenance
issue since they tend to fall off from time to time and need to be re-glued.
Does it work? Sure it does, but it's not that much better than a traditional lazy jack system to make it worth the cost to have it done when I replace the main in a year or so. I'll be going back to a lazy jack system like I had two boats ago, it pulls back to a hook on the mast
when not in use. I found that after the sail had been flaked and stowed a number of times with the lazy jacks it tended to stow relatively easily.
Even better? I didn't have to have a sail cover
with all the extra slits in it that have to be fastened when putting it on only to have them all blow open in a good breeze, it seems I have to do repair work on the cover too every year.
It all depends on what your intended use is, in my case it wouldn't be my first choice.
