I just purchased a 1987 Hunter 31 and due to the high amount of crazing of the compass and port windows I went ahead and replaced them. Then my wife and I fabricated a Sunbrella boat cover with grommets and home depot bungee cord/hooks that covered the boat from the mast to the stern to mitigate dust, dirt and bird debris infiltration, UV deterioration of 6 winches, wheel, instruments, varnished teak, companionway, port windows, etc. Feel free to contact me for details.
