These are useful comments Etienne, similarly the notes from Paul.

You see, I glued the sheets together this weekend and realised the scarf joint was not as straight or as perpendicular to the sheet edge as it should have been, outcome: a less than great fit - a low point and a bit of excess overlap. I didn't quite realise while setting it up the extent of the mismatch in the end. I'll chalk that one up to experience... (and put some photos up soon to help others from my mistakes

Anyhow, I decided to carry on rather than try and split the join and rescarf. I figure there are quite a few opportunities down stream to fix up the errors - and face facts, I always intended to paint not varnish this boat - but my concern is the impact on tensioning up the ply when I stitch it. I figure if I try and fill the lows with microballoon/epoxy mix now it will impact the tensioning of the ply. I'm guessing it will be better to address it after it's stitched up.

Current status is that I've got the full length pattern attached to the doubled sheets, sheets glued round edges with hot glue, pattern stretched straight and glued on edges, hull pieces cut round with a sharp knife and will be jig sawing this week. I'll start posting some pictures to the forum and to my blog when I actually have the hull stitched.
