The water tank support was pretty naff, a sheet of ply was glued accross the bow of the boat with some kind of filler/grab adhesive. This glue had been used all over the boat and where it had become wet it was falling off. I concluded it was unlikely this would bear the weight of the water.

I decided that I would have to make a new support. This was a learning process.

Piglet model #1, the wooden years.
Attempt #1 was made up of three 'beams' running from side to side, these were joined by two front to back beams. Two legs per beam gave vertical support. It was rubbish.

Piglet model #2, metal mania
Thanks to the kind people at The Farriers cottage in Avoncliff for their power, I was able to cut and weld a metal version using 800x400mm box steel.
This is the current model and appears to be holding up very well with a full tank of water.
