New chainplate

The old backstay chainplate was mounted inside of the lazarette and giving unnecessary extra load to the transom, which of course, with the years had got bended improperly inwards. Alex removed that old chainplate and built a new one in 1/2 inch (12,75 mm) stainless steel that is mounted on the outside of the transom instead of inside. The chainplate is cut from a 316L steel plate and has been bent under heat. The process of bending it, drilling the holes (countersunk) and polishing of the plate took Alex around 12 hours in total. The chainplate is now fastened with six bolts, two of them has encapsulated nuts inside of the new plywood knee which is glassed in place. The four remaining bolts goes through the knee and the transom. Will show you the inside and the glassed knee when that space is tidied up if that could be of interest. Just too bad that we need to remove the boats name from the back and move it somewhere else on the hull, but at least we've got the backstay issue out of the way and the transom has slowly been forced back into its right shape. This installation should definitely give a more even load to the transom.

This is how the boat looked from the back before the new chainplate installation. Nice from a far with the name clearly visible, but not so safe nor good for the construction cause if you looked close enough, you could clearly see that the whole transom was being pulled inwards by the old chainplate.
