Unregistered | The was a brief discussion in the recent Stealth video thread about mast raising. Rather than hijack that further I'd like to start a separate discussion and am interested in hearing from folks about their mast raising techniques, especially when solo.
I have so far mananged to raise the mast on my Blade solo from the rear, based more or less on the two-person method described on the AHPC site. However it's pretty hard work, and I don't feel real secure. I tried rigging a line from a trap dogbone to a block attached to the forestay bridle to enable me to provide some forward pull while I'm on the tramp. I'm unsure whether that was actually helpful, but it at least made me feel a little more secure.
Stephen Medwell described how A cat sailors in Australia raise from a 45 degree angle to the bows, and this method is also described on the F16 site. I tried this yesterday and just couldn't make it work. In order to get the near shroud attached before raising, the angle really does have to be about 45 degrees, and what I found was that I then ended up having to straddle and then step over the bow of the near hull in order to be able to walk the mast up.
I'm wondering if I'm trying to do this too slowly - since I'm still learning the dynamics of this thing I'm a little tentative and doing everything slowly in an attempt to maintain control. Maybe I need to be more agressive and just push the thing up in one rapid motion.
What are the rest of you doing?

Unregistered | Sure, and most of the time that will be fine. Nonetheless I really would like to know I can do it by myself if I need to.

I've found it helps if there is some breeze and you can rig with the wind behind you

1. Remove the boat fromt the trailer and place it on the dolly next to but a bit behind the trailer.
2. Connect the pin in the mast base and rest the top end of the mast--at about 30-40 degree angle--on the front trailer mast support. This is a good time to get all the wires sorted out and connect the top of the trap wires. Also, run the spinnaker halyard at this point and tie the loose end to something.
3. Hook up the forestay/bridles and side stay on the trailer side.
4. Get the spinnaker sheet running through its block next to the other side stay and then tie the sheet to the unconnected side stay.
5. Push up the mast, watching that you don't trip on the bow.
6. While holding up the mast, tension the spinnaker sheet; that pulls the unconnected side stay right to where you need to connect it.
7. Walk around--still holding the sheet tight--and connect the side stay.
To lower the mast, just reverse the process, beginning with attaching the spinnaker sheet to the side stay.
Oh, and once again, don't forget to run the spinnaker halyard before raising.

Unregistered | Hi all, amazing how many different systems to get mast up. Of course I think mine is best but you are welcome to dissagree. I have been using this system to raise mast on my own for 8 years or so. In our area winds can be very high so it is also designed to give total support and control at all stages. First boat is on rollers pointed into wind. Mast is layed on ground straight in front of boat, bridle is already in place, mast step is lifted into position held in place by pin. All stays and trap wires are attached to mast and layed on ground, forestay is tied loosely to bridle, (giving it enough rope that when upright mast lays back against forestay as it is past vertical). At this stage I tie or clip trap wires to rope on main beam that later take the turning block for spin. (if you dont have these you can put light rope on beam just for this job and leave it there). Then I slip sidestays in between ropes at bottom of trap wires so they don't swing about and get tangled up. Now I run spin halyard and tie end to bridle again stopping it from getting tangled. Then walk to what ever height it is OK to pick up your mast at, and raise it over head and walk toward boat walking hands up mast as you go, until it is upright then let it rest gently against forestay. It is now held sideways by trap wires and can not fall down, so you can move side to side and connect sidestays. Then move traps to normal position and tension forestay and tie off. The advantage I have found of this system is the only thing you need to step over is the bridle and there is nothing for stays etc. to get caught on. Something I often find myself helping others with rear raising masts as they get caught half way up. Hope it makes sense to you all. Regards Gary. | | | Re: Mast raising

Well,
I just hook the stays up except the forestay and walk the mast up from the rear. But I'm 6 foot 2 and I have no trouble lifting the superwing mast above my head and stepping onto the trampoline from the rear. Then again I singlehandedly walk up my 110 kg boat up a sandy inclined after sailing so I guess I have well developped upper leg muscles.
Mostly I ask a passer-by to grap a trap line and walk forward to keep the mast up when I step of the trampoline and grap the forestay and fix it to the bridle. Than I thank the passer by for those 10 seconds of his time and I tension my rig from the rear by pulling on a trap line with my mainsheet and adjusting my side sid. This I can singlehandedly.
When nobody is around then I just tie a line to my forestay or trapline and run it through the shackle of the bridles so I can pull it tight when the mast is up and tie it off loosely. But honestly this has not happened to me often. Up till now there was always somebody around to grap the trapline for 10 seconds. Any person (not only cat sailors) will do.
At one time I though about placing a strong bungee between the forestay and bridle strop. With the wind coming from behind a relatively small force would be enough to keep the mast up.
But the idea I really want to try it to tie a line to my forestay which I run through my bridle shackle and then through both the spi halyard cleat and the maintraveller car before I tie it too the main halyard itself. This creates a loop that is slack when the mast is horizontal, but when the mast is raied the loop tightens and pull the line through the shackle AND the spi halyard cleat. When the mast is almost upright the loop goes tight and pulls the line into the spi halyard cleat. Now the line to the forestay is secured in the cleat and the mast can't move back. And this system can be execute in reverse where you uncleat with your foot while pulling your mast backwards.
Does anybody understand what I mean here ?
I really believe this to be the most easy system and quickest system. But I agree that it will only suit poeple who have no issues with walking up the mast from the rear singlehandedly. I, for one, have no such issues.
I can't step from the front as I have a selftacking rail that sits right in front of my maststep.
Or should I draw out my idea for you guys ?
The amount of slack when the most is horizontal to a tight loop when it is standing upright is about 2.1 mtrs (= nearly exactly the distance between the cleat and rear traveller car. The use of the traveller car is important in this loop method. As it causes the loop to tighten at the right time and take out slack/pulling the forestay in to its final poistion..

I'm sure a more elegant way is possible

Posts: 9,582 North-West Europe | At one time (different baot) we used a beer crate as a intermediate stepping platform before making another step up to the trampoline. I always wondered why no-one with issues stepping on to the trampoline just didn't make himself a small stepping platform at halve the height of the trampoline.
just a wild idea !

Well standard practice overhere.
The F18 and F20 guys even step their masts when the boat is still on the trailer. They drop the mast when the boat is first set on the trailer. The leave all stays attached and even the spi pole stays on the boat and hang in its own rest that is just below the one for the mast. This way they can rig when coming from the trailer very quickly. Thay however have one man on the trampoline lifting the mast up with the second guy only helping in the first meter or so. And they raise 21 kg masts (45 lbs).
I'm about to go for the same setup method.

That would be a an impressive trailer Anyway, I rig on the trailer and stand on the tramp supporting my 13kg, 8.5metre, mast as I figure that my weight plus the mast has got to be less then two sailors on the tramp if the boat was two up, my boat also has the advantage of a fore and aft centre beam. The boat is supported by the main beams, not the hulls when on the trailer so no harm is done. I also rig up fast, contrary to other advice, I can do it in 20 minutes from arrival to hitting the water, as I do it a couple of times a week and I'm there to sail, not stuff around. I have noted that some sailors of various classes seem to prefer rigging and unrigging to sailing as they spend hours and hours at it then nip out for a half hour sail. Strange behaviour Darryn | | | You mean something like this ?

A lot of people these days are using swim "noodles," those long cylindrical foam things that kids use in swimming pools. They put a line through it lengthwise to tie it around the hull. They seem to use them in pairs to provide more foam under the hull at the resting points. The really BIG noodles work best, but the normal ones are fine, too. | | |
