We started out on an '89 H28. Great little boat, a few things we didn't like but isn't there always something. The aft cabin is rather cave'ish but works well just the same, for us the biggest complaint was the floor of the head, due to it's location, the floor is not flat, so when sitting down upon the throne, your right foot is trying to find a home on a slanted surface, didn't bother me so much, wife HATED it.
The Vee-birth is comfortable enough (we used the cave as I am over 6 ft tall and the admiral was left with no foot room) and has a little screen to pull across for privacy.
We did find it a little inconvenient to crawl across the settee's to access the forward birth and the table was not of the best design, 20 years might have had something to do with that too but the fold-down sides would not produce a flat table when unfolded. Mostly little gripes, nothing that would stop me from recommending it though.
We also found Hunter service to be first rate, we required a new prop strut when we bought and I could of had one made but the nice people at Hunter had one on the shelf and I received it in a matter of days, price was reasonable too.
If I had any complaints with build quality, there always seemed to be a few more cracks thru the gel coat after spending some time on the hard.
One more thing to consider is resale value, while it is a perfectly good boat, when you choose to sell it, the prospective buyer will be reading the same articles that you are now. And listening to all of "those people" that keep harping about how bad a Hunter is. Just something to keep in mind.
The catalina 30 is a good recommendation, definitely worth looking into and they have the added bonus of a good reputation.
If you really like the layout of the 28, you may want to consider the 30. Much nicer down below, bigger aft cabin that is not so enclosed, better engine access, flat floor in the head.....
Have fun, see lots of boats, take your camera and a notepad. After a while, all the boats seem to blend in the memory, and some of the details can get lost.
Most of all don't get discouraged. When we boat our first boat, we looked at about 30 others before finding "the one". Our second search was a lot more work, easily saw over 50 boats.
We lost count of the number of boats that were "well maintained and in excellent shape" that had damaged keels/hulls/engines, broken stuff, rotted stuff.......
It can be VARY discouraging to drive for 4 hours to see your dream boat only to find out it that is might have been, 20 years ago (when the pictures were taken).
