Thank you ben2go
Yes Big scarf joint the port stringer 9.5meters x 45mmx150mm and bloody heavy the scarf was 550mm long was worked out at 1:12 ratio so for every 10mm think I went 120mm long or close enough. Am very pleased the way both scarfs have come up they glued up strong and once the deck shelf goes in and bolts up to the stringer I’ll pay particular attention to the scarf joints and put a few extra bolts through for added support they shouldn’t give me any trouble all the ribs have been screwed on with 8 screws in each 2 x bronze screws on the chine stringer 2 x 304 ss screws in the mid stringer and 4 x 304 ss the deck stringer so very strong now compared how it was most of the ribs where just hang there providing not much strength at all.
