Perithead For patching sails, I have bought just a normal sail repair kit from some website,not sure which one.

It came with thread, needles, sail palm, cloth, dacron tape stuff and maybe a few other things. I have patched a 3' rip in one sail with it and its holding up pretty good. I keep the kit on the boat just in case too.

I suggest you jsut search for a good prices sail repair kit....

looneytuner Check to see if there is sail repair tape on this site?

N0NJY Well.... I got my new rudder and tiller assembly in a couple days ago, put it all together and set it on the grugeons. Looks COOL!

I still need to find the right materials for patching a sail though

N0NJY It was a very warm day with no breeze, so I took the opportunity to work out the sail rigging, raising them, lowering them and made sure I understood how things went together.

Was kind of fun.

Learned how to do it, and take them down. I'm happy.

Looks like I might be ordering a new rudder though, one that kick up.

There... raised it. now what?

Can't find any water.... grrr

N0NJY Ok.. back to one of my original questions.

The rudder....

Suggestions?

Quote:
Questions.

Part I

Ok... rudder with the boat was broken some how, snapped off near the bottom pintle. The owner prior to the one I bought it from apparently repaired it and the last owner (of one season) had no real idea that it was broken off - I think. He seemed to be surprised when I pointed it out.

Anyway the repair was accomplished with two heavy pieces of aluminum on either side of the rudder, with a handful of bolts pushed through and apparently some kind of glue on the broken spot.

Other than going out and purchasing a brand new, $900 kick-up rudder - I was thinking of building a new one.

I've read the several threads here, but am still a bit confused about what material. Seems like most suggest some kind of glassing on the wood.

Any other suggestions on what materials could be worked into a good rudder assembly? (I don't want to spend 900 bucks if I don't have to just yet).

I have wood and metal working skills.
Anyone?

N0NJY Perithead,

Thanks for the information from those notes you made.

I did do something like that.

I still need to actually build something for the stern of the boat to pull the mast up on, probably some sort of pole, using the rudder mounting with a roller device.

In the mean time, I took your advice and I used a 1 by 12 board that is 8 feet long.

I used that because 1) it was the correctly length, 2) I could put a notch into the wood that was the right size for the mast, and 3) the mast won't fall OUT of it (like it would off a 2X4).

I simply bungee corded the board in place into the cockpit and the easily walked the mast up onto the board.

I was able then to connect the bolt holding the mast to the housing. Worked good!

Anyway, over the course of the last couple of weeks, I worked out a gin pole.

I took a metal pole that is about 1/3rd the length of the mast, too a U-shaped mounting bracket and mounted it to the base of the mast at the pivot point.

Next I drilled holes through the pole for a pin-bolt and attached that.

Then I put a U-bolt on the end of the pole where I connected a block - a double pulley.

On the U bolt I set up a bridle of sorts to keep the gin pole pulling straight.

At the bow of the boat I put the other 2-pulley block and finally I ended up having to use the mainsail halyard as my hoisting connection from the top of the mast to the gin pole (I couldn't figure out what I would do if I use the front stay to hoist the mast into place then have to disconnect the thing, then reconnect it etc).

Yesterday my wife and a friend who came over to help to make sure things went well, and we had a couple of strong guys to be there "just in case" something didn't work right and we had to man-handle things into place were ready to raise the mast.

At noon yesterday I was alone and connected the gin pole, the block and tackle, double, triple and quadruple checked all the stays, the shrouds and every bolt, pin, turnbuckle, cable, line and all the parts I'd just slapped together.

Everything was in order, and if it wasn't I fixed it. (Remember, I've not raised this mast up yet, and it's on my property instead of in the water, and on the trailer).

Everything looked good.

JoAnne came back from her quick shopping trip and climb aboard to help, and our friend Steve - a buddy from 20-some years ago who lives just down the street came right over.

He's the big one of the three of us, so I gave him the most difficult job, putting the pin in the connection point at the bow of the boat. JoAnne was the mast raiser... He thought he was going to have to muscle things into place

Anyway - long story short... it took about 3 minutes to get the mast from the semi-horizontal position to upright and vertical and to get the pin into the bracket and bolt things down.

We were about a half inch off... so I pulled on the jib halyard, pulled the mast slightly forward in the center, which lined up the brackets, the pin and there we go!

The mast is up!

I'll post some pictures tonight when I get home (I was pretty tired yesterday and haven't downloaded them yet.

But - I'm happy. My wife can almost raise this thing alone, with no winds, and on a "level surface" -- ok, it can be done in the water, I'm certain.

The gin pole is the coolest thing. I can disconnect it and stow it now and sail.

All I gotta do now is find some water......

N0NJY Thanks!

I've got the hardware to do a gin pole and I'll look at something that will allow me to brace the mast properly that won't be too big, bulky and is easy to stow.

Perithead Oops, forgot to add that you can check the website in my signature and go to the Sailboat Projects page the Modifications and check out the Mac 25 there. It has some decent pitures and descriptions of a mast raising system and some on the rudder.

It might help, but I bet if you looked around the site a little you would find some stuff that would.

Perithead N0NJY,

I think I can help you on this one.

I used to have a Mac 25 a few years ago. I had a very simple and cheap system that allowed me to raise the mast all be myself pretty quickly.

For you first problem, putting the pin through the mast and step, I had a simple 2x4 with a V cut into the top of it. My Mac didn't have that little box in the back of the cockpit to house the fuel tank, if yours does you may have to rig the system slightly differnt. Anyway, I would take the 2x4 that was cut I'd say maybe 4' or so, not sure you can figure that out. I had the 2x4 standing upright at the very back of the cockpit and I had it tied to the sternrail where they touched. Sometimes I would have to have another rope to hold the 2x4 from slipping down.
I would take the mast and set it in the V of the 2x4 and slide the mast back till the hole lined up. (the 2x4 needs to be any height so that it is like someone holding it up for you when you put the pin in now)

That was the first step and got the mast about 1/3 of the way up.

I had another board, a 2x10 with another V cut into the one side of it. I would put the bottom of it in the cabin braced against the bulkhead with the winch in it. I would lean it forward towards the bow of the boat and rest on the sliding hatch when it was all the way opened. I had the 2x10 cut so that when I lifted the mast as high as I could off of the 2x4 while standing on each cockit side seat so that I could just barely set the mast into the V. The reason I used a 2x10 is because I couldnt hold the mast perfectly steady when setting it into it and the 2x10 gave me a little larger target to set the mast into. Also, I would run a line from one lifeline stanchion, around the 2x10 and to the other stanchion, this would prevent the 2x10 from sliding left and right.

Once you get the mast to the 2x10 you are 85% of the way there. Now, just step up onto the cabin top and stand the mast up and push it all the way forward.

I also had a small rope tied to the mast so that I could hold it up while I eased forward toward the bow to attach the stay.
