Hello All Mark 2 & 3's,
In my discussions with Formit's salesman, he did state that they regretted allowing some [number unknown] Top Hats leave the factory with the decks to be attached by the new owner.
From what he said I believe there may have been some problems, but I have never been able to confirmed this.
If your attachments do not look like Tom's drawings, then you may have one of those Top Hats.
I would therefore recommend that you have a shipwright or someone with expertise look at your deck attachments if you are having problems with deck movement, water entry or if the fibreglassing appears to be poorly done.
As far as I know this is not a problem with Mark 1's.
Phillip.
