Ya'll sure build em' different down under. I'll take somepictures of the hull later this week. We have our ribs on almost 16" centers and we use rough cut 4x8 or 4x10 material with a little arch in the rib. We also run a ton of 2x12 material on diagnal and stem to stearn.
Sorry for the blurry crap, old camera I guess. I'll be in the bilge after christmas, were painting the whole bilge to get rid of the smoke smell.
