Actually, if the strap could go over a roller on the short end, then over an extension of the mast support in the center and then attach to the mast end, so that the strap is pulling up on the tube (like cranes) then I could see it being supported much better.

Jake, I think there would be a large difference on the mast base. Yours is trying to lift the mast off the base before the mast raises. The other system is more like lifting the mast from the top.

Hey, I just had a thought. How about drilling a small hole in the mast and dropping in a small purple pill???

One issue I have with my Nacra 5.2 is that the mast does not have any way for me to capture the bottom (foot) of the mast. There is no place for me to lock it; no pin, no holes or anything. It just sits on the ball. So when I am raising the mast, I have to have someone, who is very brave, hold down the base of the mast until I get it to about 45 degrees. When I am lowering the mast, the very brave person holds it down until I get it to about 30 degrees and then it always pops out. If I have not gotten far enough back, the masthead drops hard. Luckily, I do this on the beach so it lands in the sand. Any ideas short of going out and buying a new base for my mast?

The easiest way to handle this is to 1)loop bungees under the front cross beam and attach them to the diamond wire. Use heavy bungee (like the black rubber ones) and make sure they are tight. 2) Tie your trap lines to the front beam. The trap lines have the same pivot point as the mast so they will stay tight as the mast moves. This works like a charm on my Marstrom

Mike,

You're right, I have been doing it for a while but I am 71.

I think there is a mind set that people need to get over. It is not difficult to raise the mast. I saw one fellow disconnect his trailer from the car and try to somehow pull the mast up with a line to his car, driving forward. It was a near disaster. Too many gimmicks and devices just cloud the issue. The best thing is to learn to raise it solo while you have help around in case of problems like fouled shrouds or trap wires. Confidence will grow with practice.

Rob,

I have seen someone tie a line from the diamond wires or around the downhaul blocks on the mast down to the dolphin striker to keep the mast base in place and on the ball while raising and lowering the mast.

I agree with Howard. I know he and I discussed this topic earlier this year. Listen to him. An H16 mast doesn't weigh that much. I too have stepped one solo using the method he described.

On the heavier masts you may need some help, but not on the H16.

Ok, Ok, Ok....but if you look at it, the position of the mast brace is no different than if you were standing on the trampoline raising the mast manually - and the mast wants to come off the ball then too but the pin retains it. You guys just keep telling me it can't be done and I'll actually have to build one!

I agree with Jake. If the bottom "brace" is in fact a roller it will work. As soon as you start winching, the fulcrum becomes that bottom roller. As that fulcrum becomes higher and higher on the mast, the lever (mast) has nowhere to go but up!

I see that this system could raise the mast up to 45 degrees or so, but not much farther. My question is why would you bother with this setup, when a gin pole would be much quicker and bring the mast all the way up? Just turning the boat around on a trailer would be more work than raising the mast by hand.
For those who raise the mast by hand, that's fine, but I've found added safety for me and my wife by having more control of the process when using the EZ-Step.

Jack, keep in mind my boat is towed backwards so there no added turning it around.

I should have the disc with PIC of the working model tomorrow.

Howard your right, some people have strange ideas how to get things done and the guy you mention should be up for a Rube Goldberg award.

Jake, keeping in mind they both lift the mast to about the same height, I still think the other one will work better. I might spend some time messing around with both ideas. I have a friend who's quite the fabricator and I'll talk him about making a couple mock ups and have a closer look.

You guys are all forgetting that most mast need to be turned 90 degrees on most boats. I think the spreaders and diamond wires would get in the way.

David your right and that was another point I wanted to make after looking at Jack's set up. I don't think your going to let the small contact point of a roller pressure the side of your mast. With the other system you could use a contoured pad on the end of the lever. It would work with the mast 90'.

The boat I saw this system on was a G-cat 5.7 and that mast has spreaders.

Thanks Carl and Les. I'm gonna try the idea of attaching the trap wire to the front beam. I'll tie down the mast base just to be safe.

I used the solo right for many years with my H21 without any problems. Don't try to re-invent or make cheap short cuts, it will cost you more in the long run.

Currently I just use a winch to raise the mast on the ARC 21. I don't do it solo but if I could train the dog to wind the winch I would be ok. I attach the winch to the spinnaker halyard because it is above the main hound and gives me great leverage and leaves the forestay free to be attached.

What I don't understand is that everyone talks about how the masts have gotten lighter but its seems they are harder to put up. I know I'm older than the average sailor (well I'm over 40) but I've always hopped up on the boat and just stood up the mast and attached the forestay. OK, if you are by your self, set the boat on the ground with the bows in a slight down angle so when the mast is in place it will lean forward and tend to stay up. If there is a breeze then orient the bows downwind. The breeze will help to lift the mast (not hinder you) and will assist in keeping it in place. If you are still concerned about it falling, tie a line to the forestay and loop it under the bridle wires and tie it off to the raised mast. You hop down and attach the forestay to the bridle.

You youngsters just need to get in shape. BTW, no I didn't sail a H14 with a little bitty mast. It was an old TheMightyHobie18 for 15 years then a H20 after that. Unfortunately I can't do that with my Stiletto but it is set up with a gin pole to raise the mast.

Wow is it getting hot in here... I see flames on the horizon. I have my sunblock, I mean flameblock on.

The average catamaran sailor IS over 40. And all of them have bad backs from trying to raise their masts without mechanical assistance.

Crap thats us!!! OK, lets see... yeah what the others said, get a winch... or just young crew. Yea, thats it, young crew.

You know as we get older we ramble too.

Mary,

You are wrong. I had my bad back long before I got my Hobie.

I hate to do this ....resurrecting an old post, but Mike can you tell me what the materials you used and the lengths used for this contraption ? It looks just to good to not try it out. The thing I'm trying to keep in mind in design is that my Nacra mast has to remain on it's side and how the contraption affects/ or is affected, by the diamond wires.
Thanks
Greg

ok, not sure how long the line would have to be, but how about this?

Take a piece of line say 25' with a double block on one end, run the loose end through something high on the mast, for a h16 you could use a shackle or the jib block, and cleat it off at the base of the mast, now, take a double block with a becket and attach it to the bridle wire. Tie one end of a much longer line to the becket than through the block on the first line, back through the lower block back to the upper block and back through the bottom block this would give you a 5:1 you could set this up in as high a ratio as you needed, than run the loose end back over the tramp, take up the slack as you walk the mast up. when the mast is stepped, undo the cleated end of the first line and the block on the bridle and your done.

Just a thought
Sam

Greg,
It's not my contraption. Just something I saw on the beach. However I think you can guesstamate the lengths. The best way might be to pin your mast and determine the lenght from the back of the boat to you spreaders as the chock would need to start below them. You also have to account for clearance at the back of the boat so the arm would be able to swing down without anything in the way.

Remember this thing gets it about half way up. It doesen't put it all the way up. Half isn't bad though. And the last and most important thing is the boat is backwards on the trailer.

I believe the G cat's mast is raised at 90' also. It would most likely stay that way easier (larger flat surface). Of course if you make the chock a little wider and flat it should want to lay at 90.

One other thing about it is the plate's that make up the piviot. Notice it prevents side motion at all points, down,up and on the way up. Very important!

I've seen this rig only once. If he comes out again I'll talk with him about it. Don't hold you breath though.

The lever is a wonderful thing.

I have a pretty sturdy mast support and a winch attached to it, up high I have a heavy eye bolt and a single block that the winch rope runs over. I hook the winch to the forestay and use the jib lines to attach to the side stays to stablize the mast side to side and have a short length of rope that I tie the mast down to the support using the downhaul assy. I just crank it up with the winch. so far its working good on my solcat 18.

instead of attaching the winch line to the forestay attach it to the trap wires. That way you can leave the winch line attached and locked when you get the mast raised. This makes it a piece of cake to attach the forestay to the bridle wires.

If you have a double trap on your boat this will work. I like to use one set of trap wires to stabalize the mast when it is below 45 deg with the trap wires while solo stepping.
