Boat Hull, one of the tutorial hulls from Delftship which has had a smaller version of the same hull placed inside and then stitched the model around the cokpit opening, not printable as it stands, and support would be difficult if not impossible to remove from the insidethis model need to be sliced up into pieces that can then be printed, I have tried deckline, which leaves a printable deck but the hull still doesnt print properly
