There is no comparison between these two boats.
The Parker is a three piece hull from a manufacturer with a reputation of building high-quality, durable, heavy boats. The design of the boat allows for more interior volume, greater access to components, and a simple, easy to maintain and modify platform.
The Sea Hunt is a two piece, foam filled boat from a manufacturer that makes production boats of a questionable quality (at least in that timeframe), and an overall goal of creating an economy boat for the maximum profit. There will be little to no access to interior components, mounting anything to the hull or gunnels will be very difficult to do properly, and the boat will feel much smaller due to the fact that there is about 4” of space lost on each side due to the two piece design: take a look at the flat interior bulkheads of the SH, as opposed to the under-gunnel space of the Parker which goes all the way to the side of the hull- that’s extra room to stand at the rail of the boat without banging your toes into the side. The glass in the hull will likely be much thinner as well, leading to a much lighter boat with the ensuing decrease in seakeeping ability.
I’ll make the very rough comparison of a F150 to a Kia.
The ONLY areas in which the Parker might fall short, depending on the prior owner, is if there is water intrusion into the deck or transom, and the fact that the tank is approaching it’s potential replacement age, although the SH will likely have the same concern. A good inspection should reveal whether these are potential issues.
There is no price point that would convince me to buy a Sea Hunt over a Parker of similar vintage.
