Create Trimaran- Maxsurf

[Eguccio]

Hello

On maxsurf i'm trying to create a trimaran. I'm only getting basic desing of trimaran so i want to join three basic yatch hulls.

Firstly i arranged other hull centre line then try to move the simple hull. But when i moved it, it parted into two hulls. I really don't understand why it parted.

After that How can i join three hulls,

Thanks a lot.

Eguccio you need to create the other surface of your outer hull. The quickest way would be the surfaces, “flip surfaces” command, pick the hull surface then tick the duplicate box, then select the transverse box and enter the position of the hulls centreline control points.

Hello

Thank you i have done 3 hulls with your instructions and i need one more help in join issue. When i use "join surface" command, it is so useless. So i think i should make surface between two hull but How ?

Or can you give advice on join three hulls with diffrent methods

Eguccio you are right about having to create a surface between the hulls as the “bond edge/join surface” will make one surface edge conform to the other as in your second picture. If you create a horizontal surface with the same number of control points and with the same longitudinal stiffness, then bond the edges to each of the hulls, you can add transverse points to get curvature. See example
