Bill,
I installed it on Julandra, and I loved it. Instructions were good. Only had to cut off 6" and it fit perfectly. Made a big difference in raising the main.

i installed it about a year ago only issue i had/have is i have a full batten main with a type of stack pack and you pretty much have to be dead into the wind to raise the sail and the be honest is doesn't stack itself but i do like it and it does make a difference in raising and lower the sail.

It will make it easier its just that I expected everything to just fall into place and does sort of but you still need to go on deck to get everything in place.

I had a Tides installed when I got my new Doyle main, (with cradle cover). I did not install it myself. As for performance, it does make raising easier and lowering is one big "whoosh"!
One thing that has made life easier on my old joints was the purchase of a Winch Rite. This gizmo, while not for sheet trimming or putting someone up the mast, is a real back-saver for raising the main. I pull it up about 2/3 by hand, the rest, albeit the last foot or so, and finish the tensioning by winch handle. It recharges very quickly, holds a charge well and you get quite a few "raisings" with a charge. I got it at a substantial discount at one of last fall's shows.

Before you buy the light weight main get the Winch rite ,it makes raising the main easy[/QUOTE]

Or, you could get a proper electric winch! Maybe. A friend had an electric halyard winch on his Nonsuch, and I recall it looked like a 16 size. Now it appears Lewmar and Harken only offer electrics starting at size 40. Anyone know of any smaller ones, or conversion kits?

If you look back, you will see my posts on installing electric genoa winches....great item, bear of a job to install, (had to move the fridge compressor). I was told that my Lewmar #30's on the cabin top were not upgradable to power and I would have to buy a new winch. I'd already spent enough with the genoa kits, wiring, etc,($4000), so the Winch Rite looked good.
Besides, I think the motor for a power winch for the halyard would really impinge on headroom.

I really like the Winch Rite, it's a great product. Obviously, this is my opinion and experience.
