I haven´t found the Hull no´s on it. But I have them on my Sleek and also in the Scarab 38KV I was helping my friend out with so I know where to look at and what.
Papers yess they´re to be found. but appears it´s and old hull.
Pre 76 me thinks.
It rides Very Rough in our waters that´s why I´m on the lookout for a bigger boat but like to have a toy too
This is our usual condition but theres a river running thru our city (as you could see from the former link I gave) and some coastal waters around.
