1984 21' Hardin Marine Caribean open bow

I bought this boat two weeks ago off of Craigslist and after cleaning it up, changing fluids and rebuilding a deck hatch I left the California rain and ran the boat for two days in the Havasu sun, the boat is way faster than I expected with the 5.7 litre mercruiser and IO. Does anybody know the history or have any information regarding this realy cool boat that I am realy excited to have in my garage. Thanks Treep

This is not too well known but that boat uses the Spectra 20 hull bottom. I remember seeing it at the Long Beach Boat show that year.
Take a look at the transom and the V angle. Take a look at the continuous strakes to the bow. Measure the dimensions.
