Cans are fine for beer, for port I prefer mine out of a glass bottle
I learned that port is red as in the beverage port
That only applies in the IALA B region. In IALA A the opposite is true...
The real significance of the red and green, port and starboard light comes in situations when one boat is crossing in front of another...
It always struck me as amusing that the US Navy insisted on using port and starboard, but gives orders to the Helmsman to steer right or left to the new heading...
A few more terms: <snip>
Sea cock - A through-hull fitting with a valve that can shut off the flow of water between the boat's interior and exterior (usually below the water line)...
Funny story (or not so funny if you were they guy this happened to or the captain).OMG! That one deserves being in the need to know list. Not so much the name but where they are and how to close them!
To expand a little, there are lots of pipes and tubes that penetrate the hull below the waterline. As Eric said, a sea cock or valve is attached directly to each fitting through the hull. The other side of the valve is most often connected to where it is needed with a flexible hose engine cooling water (supply and returns), sewage dumps, bilge pumps, etc.
Hoses eventually fail, which causes the boat to take on water as in sinking! Several people onboard need to know where the sea cocks are and how to close them when the bilge alarm starts going off. Oh yeah, you also need to learn what a bilge alarm(s) sounds like so you dont assume the reefer (refrigerator) door has been open too long.
Also on the need to know list is how to deal with a fire. Find the fire extinguishers and learn how to use them unless of course you feel like swimming home.
Theres a lot more to know about boat diving than a giant stride and a back roll.
