    Hi all.

    I am looking at building myself a 4 mtr Rib out of a larger mould that i have borrowed. Has anybody got an idea of what would be a strong layup using Polyester.

    Regards

    Rather than the use of the boat, it should be clarified whether it is a boat for pleasure or business and the type of navigation performed. Not to forget, among other things, speed, displacement and distribution of reinforcements.

    Without resorting to mathematical calculations or refer to the rules for calculating the scantlings of ships, just common sense, I can sense that a boat of 4 m, inflatable, weight of 300 kg has to be further strengthened than another, similar, 50 kg of weight.
    I've never been able to calculate scantlings of any boat through some pictures.
    But what we need is trying to answer the question of grp.boat, not to discuss with us.
