installing a mast gate?

I've been contemplating a mast gate to hold the sails slugs in the mast slot. This one looks interesting and I wondered if anyone has installed one? http://mastgates.com/Home_Page.html

I use a stop for the sail slugs. This is the one I use http://www.sailrite.com/Sail-Track-Stop-Flat-42

I attached a small line to it and attached the line to the mast with a screw to prevent losing it.

John, yes, I should tie a line to my sail stop. I've lost two of them so far.

The reason I'm thinking of a gate is that I would like to have the slugs be able to slide past the opening. It would make it easier for rigging, reefing, and stowing the sail on the mast.

DOH!

- the answer to what I just posted ... :oops:

BTW, how exactly did you attach the small line to the sail stop?

Oh, nevermind, just answered my own Q - I see the hole in the flat part ...

These mast gates are pretty cool. I especially like the internal one but I don't think it is an option for the DS. I just measured my DM284 mast and the track depth is about 0.050 shy of the 3/16" clearance required (i.e. 1/8" lip plus 3/8" slug plus 3/16" for the gate. Of course you can shave off the slugs if you want, or get the external type.

I installed a quick and dirty gate to augment my stop last spring. It was just a plate hammered into a curve with 2 screws tapped in the mast. I am hoping to upgrade it to something more automatic such as the gates KC is looking at. By I'm choking on the price so I'll probably make my own version. I think a 3/4" x 9" x 1/32" strip of aluminum bent into a slow curve, slid into the track and screwed in on one end should give me the automatic internal gate I want for about $7.

OOOPs, that didn't work, still thinking...

Luff rope

Are there any advantages of a luff rope over the sail slides ?

I don't believe there is any advantage to a bolt rope. Though, to be class legal for racing you need to use that set up. I much prefer the sails slides. I think with this sail track gate that it will complete the setup.

I can see the convenience of slides when you can leave the sail rigged between uses. But what about those who dry sail their boats and unbend the sail each time? Slides would seem so much more fiddly than feeding bolt-rope into a slot.

Green Lake,

Interesting, I find feeding the bolt rope to be fiddly. Maybe it was my boat. I always had to carefully feed the bolt rope with one hand while hauling the sail up with the other. It always seemed like another hand would have been helpful. My modus operandi is to raise and douse sail while underway, usually single-handed. If the slides are fiddly at least it's done in the parking lot before launching. Check out this short video. Does this seem fiddly to you compared to a bolt rope? http://www.youtube.com/watch?v=9zB86FML ... r_embedded

I find using sail slugs a lot easier than the bolt rope. My bolt rope got jammed more than once. I haven't had any problem with the sail slugs jamming in the slot.

OK, it's boiling down to sailing conditions again. I attach the sail when I'm in the boat at the dock, and raise it immediately. So there's not as much benefit to me in separating the steps of attaching and raising the sail.

Some boltrope designs need more babying when raising. My old sail had a bolt-rope encased in sail cloth. That did not jam and was a snap to use. The new one has the boltrope that's sown to a tape which is then sown to the sail. That one does need guiding or it will jam.

I'm still just as fast raising it alone as with a helper, but by now, I've worked out a routine that compensates for the missing third hand.

Nice video, and I can see the attraction to be able to raise and douse the main quickly and positively, just that those situations tend to be rare the way I've used my DS.

Holstein- I believe there's small inefficiancy in airflow as windward air (high pressure) can leak to the leeward side (low pressure but faster) of the mast/sail foil through the slug/slide-attached mainsail. BYW slugs are used with a boltrope channel and slides run along a track that is attached to the back of a mast, but these definitions seem to be evaporating.

Greenlake- when I first got my DS it had a boltrope main and a hank-on jib. I had never before used a boltrope main but I already knew I didn't like hanked sails compared to furlers (except they can be jiffy reefed which is cool). After a few sails it became my number one first priority to convert the main to slugs, which I did with my trusty little grommet kit (Isn't it fun to bang things with a hammer?), and, after purchasing a new Intensity main and jib I converted the main to slugs AND removed the jib hanks and put it on a furler.

My big reason was so I could leave the sail on the boom and the boom on the mast stub. But I hated the way I had to feed every foot of luff to raise it and had to pull the sail down to lower it and especially didn't like the way the sail fell uncontrolled all over the boat having lost its' attachment. I did like the smooth and wrinkle free furl but that doesn't count for much since I don't race and I actually like nice soft sails.

Jay - maybe it wasn't you, but in my ongoing scouring of the old posts on this board, I'm nearly certain I saw a reference from you about a mast gate commercially available for about $20 and posted a website. I've looked and looked and can't find it again... Does that ring a bell to you?

Yes, I vaquely recall admiring someones mast gate handiwork, but like you I cannot find it again, although Tom Luques website and internal mast gate product seem very similar but 3 times the price. I've spent some time playing with my own designs, which are similar, but cannot improve on his basic gate.
