Grumman 6k

Wondering if anyone has seen one of these. 16’, looks to be an early Royalex material. Not much info on the internet…they must be pretty rare. I’ve also posted it on the classifieds since this is a spare for me and i really dont use it much. Let me know if interested and I will send pictures.

It is in great shape, with the exception of some wood I had to remove due to water damage…in the process of replacing.

Saw just one, many years ago.
A promising stat, but then no follow up.
