dlsflorida, Good to see another Hunter Cherubini
owner here! I too have a similar boat, an 81 Hunter
27, although I haven't set foot onboard her yet. Purchased my boat a few months ago in preparation for repatriating to the States next April and intend to be living aboard
the boat and sailing up and down the east coast
for the following year.
If you are interested, I have basic drawings of the Hunter Cherubini
27 which include electrical
systems. Also I have copies of the Hunter
27 Owner's manual and an advertisement brochure from that era (Kinda cool nostalgic stuff). PM me if you are interested and I will be more than happy to share my info with you. And I will pick you brain about the layout of your boat as I haven't been on mine yet and am armchair planning at the moment for outfitting and modifying my boat when I get Stateside.
FYI, There is a forum here for Hunter owners (listed under Builders on the site's menu bar). Best of luck with the rudder
gland packing repairs
