Night Sailor, best I can explain it is a capacity plate ain't no different than Confederate money. Not worth the crap it was printed on.
However, some jurisdictions have made it their rule to require them basically to make it easier for the policing authority to write tickets.
I've had two boats that had bogus capacity plates made for them for the purpose of overhorseing the boat to try and fool the game warden or coast guard.
The "History" section is probably the closest thing you are going to get. But it does not have weight/passenger capacities.

So the 1985 Fish20 weighs 1920lbs (V20 norm) max hp of 235 and 60gal fuel capacity.
The 1989 Fish20 weighs 2150lbs, max hp of 235 and 60gal fuel capacity.

You would expect your 1987 to be the same.

Maybe this link can help:
Calculating Boat Capacity

Even though it says Pennsylvania, you get the weight capacity by multiplying the number of people by an average weight of 150lbs. (weight takes into account people and gear, not motor). You get the number of people by multiplying the boat length by its width, then dividing by 15. Figure out the max HP for your motor, get its weight and there you have it.
