hi hunter sailors,lately i've been trying to figure out an effective way to improve ventilation on our hunter 23.5. i really don't expect it to cool the cabin but i've noticed when i open up the boat during the summer to work the interior is pretty hot. i would like to add some passive vents that are weatherproof and unobtrusive. one idea is to put a vent in the door of the forward hatch. vetus makes a low-profile vent called the UFO. i'd like to be sure the hatch can be fully opened once the vent has been installed without banging into something (deck or window).i have also thought about putting some type of inexpensive ports (maybe even a couple of clear beckson deck plates) into the cockpit somewhere for ventilation (and some light too).i'd be very interested in hearing from anyone who has added ventilation of this type to a 23.5, 240 or similar, and whether you are happy with the results.thanks to all, ed (hoy hoy #5)
