It does seem as though the ants are mostly running between one place and another, but the extent of their territory is quite worrying. I have removed the mast foot fitting (for fixed mast) which exposed the older, currently unused rotating mast foot fitting which curiously is a female fitting. (opposite to the fairy /reynolds mast fittings) and so it naturlly tends to fill with water that cannot drain. In invitation to rot!
This fitting is a 1/4 inch tufnol as a bearing surface screwed down to hardwood block that takes the weight of the mast and bears down onto a central longitudinal bulkhead that transfers weight to the keel.
That part is clearly in good condition s it has sailed for 2 seasons now without showing any signs of weakness.
There are however ants appearing from under the foot and also from under the blue foot grip diamond pattern surface.
There is also evidence of a previous repair on thr starboard side of the mast foot and I strongly suspect this is a temporary repair, which leaks. It allows rainwater to enter by runnig down the mast groove, and while afloat the mast foot is in the "sump" of the boat, and at the end of a race I am often carrying up to 2 gallons of water inside the hull. To this you can add a bucketload of sand from the Worlds at Pwlhelli
(I have also noticed darkening wood around the shroud plates and as there is some movement in them at deck level this also needs inspection.)
Back to the mast foot, I have peeled back the flooring and revealed a marine ply pate somehow screwed from the inside of the hull to the floor panel close to the forward bulkhead, and about 6 inches square of Chopped fibreglass overlying it.
I can see several bits that are not watertight.
As it will all lie under the nonslip floor surface, I believe it will be possible to cut away the offending 'hole', and than let in a panel of ply and carbon matting before re-gluing the surface flooring. The mast foot heeds a small hardwood block to bear the foot fitting and this may even solve my leak.
Pictures are tricky as Photobucket now charges £20 per year for linking with other websites, and I am too mean to pay for this! but if I enter the url in two halves, without the inittial "http//"
You may enter the code in your address bar then close the "space" between 'michael' and 'brigg' to give the correct address. the relevant code to reach my file on Photobucket. In the Photobucket site navigate if you need to to my "International Canoe" file, pages 1 and 2....Good luck!
