We bought ours for different reasons, I did not worry about ratings and numbers so much. The big things I was looking for were:
1- Deck to Hull that was actually bolted not screwed
2- 32 to 38 ft long
3- 10ft beam or wider
4- older thicker hull (pre-1980)
5- none to very few small soft spots
6- Priced under 15K
We found a 1978 hunter 33 that fit the bill.
I would have rather had a 2 masted boat but that was not a must have.
We will be working over the next several years to get her to Cruising shape.
Would love to share ideas and thoughts about the whole process.
