I think the 89 30ft Sundancer is ideal for short cruises with kids your ages. We did great with it when mine were that age. Parents in the forward berth, 1 kid in aft cabin for privacy and one the converted dinette berth. Later it became parents in aft with curtain closed, kids and in the forward with tv and video games till bedtime. Sometimes one will want to sleep at the helm on the bench seat. The booth style dinette with facing seats and large table works better for family of 4 meals, card games etc than the settee table found more often on newer boats. The big flat foredeck is good for lounging. The 30' is roomy (don't confuse it with the late 89 "30" which is like a 28 and different hull. The 85 to 89 are the same hull. A couple of suggestions if getting this boat. Extend the canvas aft so there will be some shade. The original forward canvas slants down to the windshield. Get it raised so air flows and you can stand with the canvas up looking over the windshield. Shade and breeze keeps wives and kids happy. I also put in two pontoon boat style bench seats in the cockpit. Seats 4 and very comfortable and can be arranged L shape style. Plus storage in them. For fishing, just slide them against the helm seat for standing room in the stern. Over a tank of gas which includes the mix of no wake zones, idling,cruising at 2800 rpm (23 kts) I consistently average 10 to 12 gal per hour - very good for a boat this size. Central vac, microwave, deep sink are appreciated. Add a grill and you are set. Go for it.
