Chotu's Rigging Thread - Time to Go Fast

[s/v Jedi]

Chotu: yes, conduit!

I am not sure how the rigger plans to install it… you don’t want sharp self tapping screws sticking out into the conduit! I have pop rivets.

Way to go.

drill through a block of wood and then chick the drill with just enough sticking through the block to go through the mast and conduit wall. Only pull the rivet until the mandrel pulls into the rivet end then release the pulling tool and cut the mandrel where it sticks out of the rivet flange and drive the cut off piece into the conduit (it will fall out or you can blow them out with compressed air)

And how to pull the conduit against the inside wall of the mast? I believe they used thin stainless steel wire on our mast because I see the cut-off ends at the rivets.

The suggestion is wire ties. UV stable wire ties

That would be in the order of 3-5* of prebend (stiffer masts can have less) and less than 1’ of rake. That way you don’t have to mess around with the rig when you get your new main, which should be designed for optimum performance and not for a rig to suit another boat’s mast settings.

I have no idea what’s going on with this part. We had to re-cut the jib. Maybe the main as well but we just don’t know I guess. Once the dimensions are in and the rig is up, I guess the sailmaker will start to look at that.

Where do you get your pre-bend and rake figures from?

My sister ship has about 5 inches of pre-bend and between 3.5 and 4 feet of rake.

No weather or Lee helm.

Can tack at 1.5 knots

I am trying to imagine someone crawling through the mast, securing the conduit with wire ties… surely the “UV stable” part doesn’t indicate external to the mast?!

One of the first questions in my meeting that is starting momentarily I don’t understand how to do this

You can zip heavy duty ones with a long tail around the conduit in a star like pattern. Than the tails stop the conduit from touching the mast walls.

Some mast extrusions have a groove to hold a conduit on the inside.

Just got done with my meeting.

Thank God, he’s installing the conduit. And he is using screws just as described in this thread. He has a whole system figured out. He was going to have to teach me much easier for him to just do it.

I will be doing the drill and fill and installation of the self tacking jib track and I learned a new and absolutely amazing way to do drill and fill! I will share later when I have some time. It’s what the highest level pros do and everyone here, myself included, will have to humbly realize we are all doing it in an amateur, inferior way. All of us.

Regarding the reefing, he was saying that we would rig for all three, but only run the lines when you need to use them. That’s what he meant. And I misunderstood him.

Obviously I misunderstood a lot of things that he said. It’s quite difficult to keep up with people at that level.

One thing that really surprised me was that I would need to use half-inch backing plate for the self tacking jib. I figured: what a tiny sail. Why?? But that’s not how it works on a boat like mine. The forces are tremendous apparently. This is because it does not heel.

So I have to order a bunch of backing plate material.

And for simplicity and speed I think I am returning to having a traveler. This, rather than redoing the davits and doing the triangulated mainsheet . It will cost more, but it will be faster.

So Chotu, how does he do it with the conduit Zip ties?

I misunderstood him. I guess they were just to hold it in place temporarily until you could get a screw in. It was an idea. He has a few different ways.

Also, I could definitely use some paid help out here. If anyone wants to work. It’s going to be tough making the deadline.

it’s quite an educational opportunity on high-performance boating.

And instead of paying tuition you can get paid. Lol

there are lots of hardware installations on deck, some lamination work to make the plinth. plenty of rigging things to learn about from a master that rigged the gunboats for a living and INVENTED the plinth they use.
Fixing some damage I took to a rudder kickup fuse holder. Installing a ton of rigging components.

Location: OBX (outer banks) NC

All the materials are now here on site. And it’s time to go.

Well, I for one, would sure like to see a pic of the boat once the rig is up !!!

I's been a long time coming...I think I've aged quite a bit since the first time I read about your boat. At least 20 grey hairs on my head are attributable to you.

You have hair left???

Lucky! Ha ha ha.

Mine a fell out from the project

I can do you one better than a picture . you still have an invite to sail, my friend. You helped design my cantilever davits.

But if you are unable to make it, I will gladly send you some pictures.

[MicHughV]

Just let me know when and where...
