It is well known bad luck for mariners to have bannanas onboard. Sorry, no bannanas on my boat either. Better please the sea gods. They are more important that you.
You know, it surprises me people don't know these things, they should be part of dive training, boat ettiquette etc. When you are on a boat, the skipper is the law and the boat is like his home, if he don't like bannanas onboard, better get oranges, that would include you guys, that or don't get on the boat, your not in charge, the skipper is.
Here are more borrowed from a boating site:
1. Bananas on board are bad luck (or anything referencing)
2. Do not look back when leaving port (bad luck)
3. Women on board are bad luck? (don't agree here)
4. Never start a voyage the first Monday in April
5. Never step on board with your left foot.
7. pouring wine on board is good luck. (offering to gods)
8. Bad luck to harm mola mola (ocean sunfish)
9. Church Bells heard on ship means someone will die.
10. Dolphins swimming with the boat are good luck
Sharks following a boat are a sign of impending death, red sky at night, sailor's delight, red sky in the morning, sailors take warning. There are tons more like not renaming a vessal without performing certain rituals.
