    hey,

    I am preparing a project for French administration. I need to know which is the difference between a "ponte" or "non ponte" boat. Although knowing that is related with the height of the deck, and consequently with the freeboard value; i have not found a clear definition of those concepts...

    If anybody has any information, I would be very gratefull of read it.

    Thanks!

    The pont is the deck. Es llamado la cobertura en Catalán?

    Le bateau ponté is therefore a decked boat.

    Quelques éléments constitutifs d'un bateau ponté : 1- proue ou étrave, 2- bulbe d'étrave, 3- ancre, 4- bordé de la coque, 5- hélice devant le safran, 6- poupe, 7- cheminée, 8- superstructure, 9- pont.


    I would take that to mean a bateau non-ponté is an open boat with no deck.

    Thanks for the information.

    Related with my question, the french code for GRP passenger vessels -division 223b- demands -for a "non-ponté navire"- a value for the freeboard of 550mm, which in my point of view it's excessive for a 12m LOA boat.

    My question is; does anybody knows if the freeboard value of a "non-ponté navire" is measured up to the cockpit floor, or to the upper part of the side board?

    In the attached photo there's a boat with an open deck -"non-ponte" I guess- with the cockpit floor and the board sides as I explain in my question.

    I believe freeboard is the distance from the normal water level up to the lowest point into which water can spill.
