I found the HIN. The boat does not have a capacity plate though. It’s a hydra sport and the company isn’t around anymore. How can I get a replacement capacity plate?
I would guess based on the boat, that you are looking at max 5 people and about 800 pounds. There is a guy on ebay that sells reproduction plates for the Hydra Sports boats that may be able to get you closer to what it is. Just do a google search for 1985 Hydra Sports VL-300 Capacity plate and a listing of his auctions should come up.
