So far today we have encountered the largest variety of wave styles to date. Most boats will have one person on wave duty. The Coast Guard opts to have the entire crew wave. Typically it's just a hand placed in the high five position. The friendlier boats will add some movement to their waves. Some atypical waves included the two fingers pointed like a gun wave, the surfer wave, the salute wave, and amongst the younger generation, the head nod.
I opt to use the moving hand wave regardless of the extra caloric output. We are a friendly boat. After we had a slight grounding while in the middle of the ICW this morning, I used the full arm sweeping wave to a passing yacht who read to us depths and offered to give us a tow off. I dub that my gratitude wave. Ironically they were in a vessel designed by the same people that made our boat.
Each member of our crew has invented their own style of wave.
Kai "the cow phone wave" - having nothing to do with his beef hotdog, he thought his fist looked like a cow with horns which could also serve as a phone when angled
Fal "the wave of peace"
K "the wave dun dun dun" (que music)
G "the ziggy"
Pip "the bark"- especially to boats speeding past us
Regardless of the wave style, if you are gonna stare at the boat, pass us some hand acknowledgement or the head nod. It makes us feel better. Don't leave us hanging- that happens out here too.
