I was going to do this with my 25 ('81), but I got over it. My plan was to come through the port side step where the cockpit coaming abuts the bulkhead, and snake the wire through the storage lockers. This should give you access to the port side cabin all the way to the head. As for specialized tools, you will need a long armed slender person to crawl between the cockpit well and the interior bulkhead to snake the wires. Buy beer for them afterwards because they will hurt their ribs. I think Steve is smart to bring up the corrosion issue regarding installation on a horizontal surface. Best of luck. Jim s/v Cygnus
