Any info on Channin "Siren" surfboard?

looks “nice” (at least for a female)

 

but seems like a fun shape too

 

googling doesn’t bring too much info

 

dead and gone, there were no longer any victims left to use and abuse

 Jim,  Now thats’s funny.   I often wondered how Diff and Tony ever got together to make Boards Diff was a good guy. The few times I met him he was great.  Tony on the other hand not so much.
