Kacper...I know nothing about this boat but she LOOKS seaworthy and well kept. If you proceed further with her, a couple of things would concern me.
1. The boat is built with a cored hull. I would not buy a cored hull but fine boats like Shannon use them so that is my personal predjudice. The main thing you need to worry about is that the hull is currently in good shape all over the hull with no delamination. Find a surveyor that YOU can trust if you make an offer and have it accepted.
2. Why is this boat priced so low? A couple of others are up near $30K and "yours" has a virtually new $10k+ engine in it. It may be a genuine deal but you rarely get a boat for 1/3 off the market price without something being wrong. Survey, Survey, Survey!
Anyway...other than that, I like her and think she looks ideal for your purposes and budget...hope #1 & 2 above are not issues!!
