Boat Hull thicknesses

had my boat in for some additional stuff to be added to it. Wanted to know the thickness on the hull sheets.

came back with 5mm transom and 4mm side and what most surprised me was 4mm kewl sheets. I dono if this sounds right to me or if it was even legal to have it this thick?

 

the boat is. 6.2 plate 7.3loa.

 Can't help but LOL at Kewl...

4mm bottom sounds fine.

It is the best spot to have weight in the form of thicker plate but not necessary unless you plan to sit the boat on rocks.

Pressed or Plate

While Quintrex continues to build its hulls in lighter 3mm alloy, which it says is all that is required due to its special construction technique, Kiwi boat builders seem to favour 4mm to 5mm bottom thickness and even one manufacturer goes as far as offering its 5.5m model with 6mm. Side thickness for most 5-6m boats by Kiwi manufacturers is usually 4mm, with a few at 3mm.
