Thoughts on ProFurl in-boom furling?
We're on the hunt for our next boat and one particular candidate of interest is equipped with a ProFurl in-boom furling mainsail. As a cruiser, I definitely prefer ease of sail handling over performance, but I've seen mixed reviews of the ProFurl in-boom system and am looking for more opinions.

A few reviews I've seen state that the ProFurl in-boom furler is finicky to operate, requiring precise tension on both the halyard and furling line to raise and lower the sail. This isn't all that surprising, since that's basically the case with our current headsail furler, but what's making me concerned is that at least one review states that someone needs to be on deck when lowering or reefing the main or the ProFurl unit won't furl correctly in the boom. If that's the case, what's the point of having a furling main!?

I'm also aware that the rigid boom support (vang) that's part of the ProFurl system needs to be adjusted to the proper angle in order for furling to occur.

So, I like the idea of easy mainsail handling/furling (particularly from the cockpit) but I'm not convinced the ProFurl in-boom system is any easier than lazy jacks or other more simple systems that definitely don't require someone to be on deck and have little maintenance/operation concerns.

Anyone have experience with or thoughts on the ProFurl system?

I have the original hood Stoboom and it does require the boom to be at the correct angle

I do this with a 2:1 cabin-top toping lift and all furling line and halyard are all lead there

This allows me to furl the main while standing in the companion way

I do not really consider it any different than my Profurl head-sail unit which makes a much tighter furl on starboard tack

No experience with Profurl, but a considerable amount with Leisure-Furl, primarily on a few Trintellas... Please forgive my ignorance of any possible significant distinctions between the two systems...

L-F is a pretty slick setup, no question... Had some problems with the earliest versions made in NZ, but once Forespar took control, they got things pretty well sorted out... Other than problems with the motorized version (as opposed to using winches to operate), haven't had any issues in the past 5-6 years, they've been flawless... On boats approaching 46-50' or thereabouts, I think they're the way to go... On a rig as powered-up as that on the Seguin 52 pictured below, they're the only way I'd want to go...

Not sure why one would say it's necessary to position someone at the gooseneck, but it can definitely be a prudent practice, especially when lowering... Many folks think you never have to go forward with these systems, but there is that locking pin that must be dealt with, so someone will have to go to the mast on occasion...

As mentioned, the angle of the boom is critical, and I think a hydraulic vang is the way to go to obtain and hold the angle with the required precision... Best setup I ever saw, was a simple batten/measuring stick fixed to the vang that - when aligned with a mark on the ram - would assure the desired angle exactly...

Primary downside IMO is the sheer weight of the boom, damn things are HEAVY (Carbon fiber would be nice, but very pricey, of course) Jibing those things on a larger boat in a blow can be hair-raising, and one had better rig a bulletproof preventer for a L-F boom or equivalent, an accidental jibe with a boom as massive as they can be could be catastrophic......

I know where you can get a used Leisure Furl boom, motorized version for a 13' boom, cheap. One of my friends took one off of the boat he bought because he wanted to race it. Original cost with sail and mast modification around 17K. I'm sure he will sell you his for a very small fraction of that amount.

Re: Thoughts on ProFurl in-boom furling?
i have used the profurl for years on my nimble30express. i have a fully battened main. i can raise it by hand halfway up & finish raising with the winch. it comes down easy by hand. the profurl vang has a pressurized gas cylinder in it that holds the boom at 87 degrees for furling. you can tighten the sheet & pull the boom down to flatten the sail. as long as you keep a little tension on the furling line when raising the sail it will wrap on the drum without over rapping . if you have any questions about it, contact me.

Slab reefing is so quick, easy, cheap , and simple, I dont see why anyone would bother to go for a more complex, expensive and potentially trouble prone sytem. I can reef my main in under a minute. Cant see much relevant improvement on that.
