Gareth,
Any idea what the Twincat weighs?
Do you have to rotomold the twinex, or can you vacuum mold it?
Is your boat vacuum molded? If so how do you get the halves to bond?
And you need to get it to 200 C to do what with it? Vacuum mold it? Does it become softer at a lower temp? Could you form sheets into a half hull at a lower temp?
Thanks
Bill
