I like your attitude, but watch out for the boat ladders... and many other new experiences that tend to magnify and multiply when they're layered atop one another.
Even pretty fish-warm water diving can have it's challenges. It can start at the docks with boat awareness as to how to come aboard a pitching craft, it can be all about "surviving" a wild ride to the dive site- not only your stomach but managing your gear and suiting up.
Exiting a rocking boat can be exciting, learning the three-point contact rule is a key to survival... taking precise instructions from the boatsman as to when and where to move is also part of the puzzle.
Knowing to hang off the tag line, or how to follow the john line to the anchor (downline) is an acquired skill.
The same with reboarding the boat- and this is where most people learn the hardest lessons. Watch above you for the plunging ladder as the boat slams down and gets tossed high upon wave. Don't get your skull punctured or neck broken in that moment. Understand how to gauge the moment, hang on and go for that upward ride!
Watch your fingers where the ladder hinges to the boat. Did you study the hand holds before you jumped in? Hand the flippers up if that's the drill.
When you reboard, stay low, mainain 3 point contact and sit down quickly. Keep your second stage reg in your mouth until seated. There might only be one good reason to do this, but there are absolutely NO good reasons not to.
Lots to learn, even for us rough and tumble cold water muck divers.
Go, have fun. If it's too rough, let me teach you four new words in Espanol:
