So, I spent some time deciding which fillets needed to be improved and made a work list.
The first thing I did was to tape out the keelson fillets, like this.
I should have done this in the first place, to achieve wide, shallow and neat fillets.
Then I set about reworking all the items on my list. By now I had become relatively expert at filleting and it only took three days to carry out all the remedial activity.
Another six days of dressing and sanding followed before I declared myself content with the size, strength and appearance of all the fillets.
At last, the agony was at an end. It felt like I had been working on these fillets for months but when I checked my log I found that the entire exercise had taken just over five weeks. I don't think that is a bad investment of time, given the importance of strong joints.
The next step is applying fibreglass to the interior bottom panels of the hull. It will be a very welcome change!
