Both of the above
The wife and I just got back from a 3 day shakedown cruise on our new(to us) 1994 23.5, It has both of the Items above and I can tell you that 1: rollerfurling (cdi) is NO problem! It IS a bit more bulky of course, but didn't give us ANY problem whatsoever raising and lowering the mast we've done it 3 times now (twice in the driveway and once this weekend at the lake)....Can't say as to the price new...but for ease of furling and reliability, I would say that CDI is the way to go (this is our 2nd boat with a CDI unit and they've been very good.)and 2, the stern rail seats (installed by previous owner) are SWEET! If the boat had come without them, I would have added them without thinking about it. Also a good set of cockpit cushions are worth their weight in gold.Regarding the Water Ballast issue, I too was a bit nervous about it, but it is simple and so far works as advertised! You can definitely tell a difference in the stiffness of the boat when the tank fills. Towing is also MUCH nicer with the extra 1000 pounds out of it. We up-graded from our Com-pac 19 to the Hunter 23.5, after MUCH shopping around and deliberation on exactly what we wanted in a boat...and for two people, the 23.5 is IMHO about the best value on the market in a trailerable sailboat.A boat this nice shouldn't be this easy... but it is!Good luck!!!
