SH14 Starting a new Sharpie called Little Mae
Re: SH14 Starting a new Sharpie called Little Mae
Yes, are close. Still some wrinkles but you"ll adjust all that on the water.

What did you use for that mast and sprit? It looks good. I am also considering making my own sail so I look forward to hearing how yours works.

Re: SH14 Starting a new Sharpie called Little Mae
After a few years I finally finished the Sharpie and got it in the water.
Not a good result but will try again.
Center board came detached and 20 ft from dock on my first turn into wind it flipped.
I have since put a metal strap over the connection point on the center board so it can’t fall off.
Question. Beside the weight which seemed ok. How does the center board stay straight down and not retract some because of the flow of water? Do I need to lock it in place somehow?

Re: SH14 Starting a new Sharpie called Little Mae
I’ve seen a shock cord used to hold the board down. That allows the board to “bounce up” on impact. There are some examples online if you search google.
Re: SH14 Starting a new Sharpie called Little Mae
What do you mean by detached and flipped? The CB pivots around a bolt. The plans show the bolt going through the CB case and the CB. How can it become detached? Did the bolt get loose? Can you take picture of the pivot bolt?MWhiting04 wrote: ↑Tue Oct 01, 2019 12:27 pm Center board came detached and 20 ft from dock on my first turn into wind it flipped.
The bolt is secured by nuts, why a strap? A picture will help.I have since put a metal strap over the connection point on the center board so it can’t fall off.
The plans show a lead insert in the CB, it seems that is right, it is sufficient for the CB to go down. Once the boat has some speed, sailing, the side pressure on the CB is sufficient to keep it from moving.Question. Beside the weight which seemed ok.

You only drop the CB when sailing upwind.
Post a picture of that pivot please, I wonder why it should become loose.

Re: SH14 Starting a new Sharpie called Little Mae
This is picture of entire center board.
The bolt does go through the boat and the center board hooks on it.
I put a metal strap where the green shows.
So sounds like while underway the board stay down because of side pressure. The board is tapered like a wing as well. Post a picture of that pivot please, I wonder why it should become loose.

Re: SH14 Starting a new Sharpie called Little Mae
I was not able to get a picture of the bolt but that does not seem to be an issue, never came loose. It is a bolt through the center board housing with a Bolt Sleeve about 1" wide so the center board does not roll on the bolt it rolls on the sleeve.jacquesmm wrote: ↑Tue Oct 01, 2019 2:45 pmWhat do you mean by detached and flipped?

See example picture I did include a picture of the center board with the U shape notch.
I wont get a chance to try again this year unless the weather does a major turn around. Seems like the strap covering the U notch should keep it from falling off again.
It felt so good for about 10 secs when I turned the rudder to get into a close reach and the front of boat started coming around. I have never sailed and going against the wind always seemed odd. But it worked, I started moving upwind but then I think the center board hit the bottom and then fell off. But those 10 secs were cool that I was doing it.
Re: SH14 Starting a new Sharpie called Little Mae
I see it now and I understand your questions.
Look at the plans, profile section, like below:
That is how the CB should look when it is down.
Positioned at that angle, it can not jump out.
Tie a knot in your painter to keep it from going deeper.
There is a description of the painter and slot here:
http://bateau2.com/howto/centreboard.php
The painter is the line that you use to raise and lower the CB.
The advantage of that system is easy maintenance and cleaning: let the board go lower and you can remove the board for cleaning or transport.
I had that same system on a large ocean going boat and the board never jumped out but if you let it go lower, it will jump out as you describe.
If you look up "sharpie" you will find this:
https://en.wikipedia.org/wiki/Sharpie_(boat)
showing a traditional sharpie CB arrangement;
that is how the SH14 should sail.
In my design, I use a slot instead of a hole.
If you don't like that system, fill the slot and drill a hole for the pivot. To clean or repair, you will have to remove the pivot bolt.
