The Irwin28 Will do fine by you. A tough boat with shallow draft that will go anywhere. The centerboard was taken out of many of then, as she sails fine without one.
The fixed port
lights were a constant battle to keep from leaking, and as said before the hull/deck joint. On my sons it got that fixed, I rebedded the toerail.
Oh did I mention plenty of room inside for a 28.
