Before any fibreglass fabric could be applied to the upper hull, all the fillets would have to be made smooth to receive the cloth.
Sanding was tedious but straight forward, mostly carried out with the 90mm random orbital sander fitted with a soft sanding head so it could follow the contours of the fillets.
Here are the finished fillets in the cockpit and on the rear cabin wall.
And here are the transom and footwell fillets.
Time to cut 'glass!
