I built one of these myself a couple of years ago, they can be a bit of a challenge to build but there's no allowance for sloppy workmanship. The windows I must say are a pain (pun intended!) and it looks like you've got a good start on these! As for the spray rails, I'm not sure if the instructions called for them to be added, I don't think I did, but they do look good and give it that Huntsman look to the boat.
I'm building the Jenny at the moment and coming along nicely. No spray rails on this either. Not sure whether to fit them or not as I wouldn't want to mess around with hydrodynamics of the hull. Wonder if or does it not.....anyone out there know???
Anyway, following this resto with gusto. Looking forward to the end result. Looking good so far!😊off
(Looks like the chine rails were initially missed off)
