Stage one of the repairs is done - sorted the back of the floor out. Went pretty smoothly for the first time repairing a PVC SIB floor. Followed these instructions http://www.shipstore.com/SS/HTML/INFO/INFOGLUE.html
exactly as written and the results were good. A few lessons learnt to apply to the next area. The next section to tackle on the floor is the front under the webbing. I have decided to take the plunge with some seam sealer SureSeal XXX. Given that these holes are very small and that it will be very awkward to get to, I thought I would give this a try to see if it is any good, if not I will apply a patch.
Next job will be a little trickier - tackling the repairs on the hull!!
