    Hello all!

    Does anybody has come across any reference to hull builds out of transversely split mold? There are numerous instances of molds split across the center line but not sectioned transversely.

    Yes, there is not a strange solution, can be done smoothly. Even molds sectioned transversely and longitudinally.

    I have known a number of transversely split moulds.They have been for producing a family of hulls of differing lengths and the hull could be extended by adding another parallel module between the bow and stern sections.No major technical obstacles to overcome.

    A mold can be made up of as many sections and shapes as desired, other than reworking the seems where the molds come tougher it makes no difference to what's being made, which would be a boat in this case.

    Thank you all. I am aware of this as a practice. ABS HSC for example has a reference for joining two longitudinally sectioned hull parts, requiring a minimum area for laminating the join and a minimum thickness. However there is no such reference in my knowledge regarding trasnverse sections. Does anyone has in mind such references?

    I think we have misunderstood your question. What we are saying is that the mold can have as many parts as you like, but to build the ship, you must first assemble the parts and then apply the hull laminate of the most continuously way possible.
