1974 23' value?

[outta bounds]

I am new to the site and have been looking for a project with my son. Came across a 23 foot 1974 seacraft with no motor. It has been sitting for approx 10 years. It appears to be in decent shape on quick inspection what are the high and low values on a boat like this. Do not even know if it for sale, but would like to be somewhat knowledgeable if I were to go forward.

Thanks this is a great site
