2 questions relating to the bow

1. I've been wondering for ages where the dampness in the front bunk - seen as a wet patch on the sheet up by the bulkhead - has been coming from. Today I opened the round hatch on the bulkhead and found that that front space had significant quantities of water in it. There does not seem to be any limber holes between this compartment and the rest of the bilge (that is bone dry). Clearly what was happening was that water was splashing onto the hatch and weeping through the seal; and I was starting to think that incontinence had started early

Looks like a slow and very cold mopping out to be done over the next couple of weeks.  Anybody else seen this issue and any idea where the water is coming from?

2.  Both sets of cables leading to the bow navigation lights are badly corroded and need replacing.  Any idea how to get to them and where they actually run once inside the pulpit railings?  I am assuming they exit under the deck behind the anchor locker molding but can’t seem to find them coming through the bulkhead at the edges of the deck into the front cabin...
