Graham Bantocks New Design "Zig Zag"

Hi I have just finished building a Zig Zag. Has anyone else built one?
I am finding that it tends to sail down by the head in most winds (even Up Wind) and in a blow does a very good Submarine impresion Down Wind much more pronounced than my "Triple Crown".

Any suggstions

Hi John,

I have built a Zig-Zag and found itÂ´s handling very good. The first time that I sailed it was in top of rig 1 conditions and I found that the nosediving was very minimal and when it did nosedive it recovered very quickly. Upwind it was very stable.

John, maybe should you check your bulb cant. Put the nose up of 2Â° min.

Hi

Thanks for the interest.

I do have about 1.5/2 % nose up on the ballast the fin is wood to the designed shape it has a cord of 6%.
My boat is about 150grm over weight so I will check if the hull without ballast is down by the head.

The photo looks very good a lot of work in the finishing detail.

I will try to find out how to post some photos. Of my boat

Regards

John

Hi Fernando.

Thanks for the photo tip I will try later.

Regarding Zig Zag On wednesday the wind was up and we all had to use No 2 rig.

Still some head down problems but part way thro: I changed to my Triple Crown Fin.
Which is a Dave Creed Fin fitted with an Anders Walllin 350mm long Bulb all up weight 2495grm which I cast .
With my fin box configeration this put the Ballast CoG 13mm aft of the designed position.
The boat trim was much better as was the performance.
