Every boat I have owned has navigation lights wired though the bow rail and then directly through the deck under the bow rail flange. They all leak !

When I look at other boats they seem to be the same. The wire leaves the rail in open hole and water must fill the bow rail piping. The wire simply goes through the fibreglass deck sealed with Sikaflex. It seems very hard to seal the wiring exit in the top of the rail.

Is there a better way to do get wiring into the bow rail under the flange ? Is there a gland that fits under the flange perhaps ?
