My experience
I have owned a Hun 25.5 (shoal draft, yanmar dsl eng, 1985) for a number of years. In general, I am very happy with the boat. It is easy to sail single handed and fairly low maintenance when compared to others. The boat is not as "substantial" as some other makes, but more than some as well. The hull is designed to be thin, but does not seem to flex (oil can) perceptably. I have put the boat through some high stress situations for an inland lake environment and it has survived well. The shoal draft version does not point as well as I would like and tends to be a little "tippy", but has been stable and controlable in some rather high winds. The reefing system is easy to use. My boat has developed a number of hairline gelcoat cracks at points of stress (like the forward cockpit corners and anchor compartment aft corners). These seem to be common in the model. The cracks have not caused any problem and I have chosen not to try a repair. They are barely noticeable. Due, I think, to improper installation, the gelcoat has cracked around the bolts attaching the pop top. These are a bit uglier, but also do not seem to be a real problem. One other issue with the Hunter 25.5 seems to be a tendency to blister. While I have had few blisters to fix, others in my area have had to have extensive hull work to repair blisters after long periods (years) in the water. For what it's worth, I put a barrier coat on the bottom when I bought it. There are mixed reviews on the effectiveness of barrier coats.Bottom line, the boat is a good model. It does seem to have a few problem areas related to design and materials, but these seem to be minor. Maintenance is relatively easy. It is easy for one to handle.
