it is a 3.5m ally boat that is a twin sponson style... like a cat or a twin hull... however ya like to describe it.. all i know is that it is a seacraft made in west oz....

i am trying to find out what is the recommended and or max motor size... (want to upgrade) and if anyone has any experience in what is the best way to find a middle ground between porpoising and cavitating.. tried a few things myself and it works ok just verrrry slowly...

i will post a pic of the tub as soon as i can...

cheers peoples..
