It depends on the water condition and which boat I'm in.
In the Marlin, I have to put the Floating Coozie on the drink at a rather slow, comparatively speaking, speed if the waves are any larger than 2'. Luckily, with the protection provided by the coozie, the drink may fall overboard, but it will float upright and if I'm lucky and return for retrieval soon enough, there will still be life in the can or bottle.
In the Scorpion it is somewhat faster and bigger waves are required before I wrap my drink. I am not nearly as prone to fearing for its life.
And in the BT, well, hasn't happened yet. Of course, you have to drink in it first with some major nasty water.....
Oh, get a windshield or hand out anti-vodka goggles with wipers....:sifone:
CC's have a lot of wind so we use sippy cups. What sucks is when the captain has to wander away from the helm since the ice bin is in the front of the console. BTW- A throw cushion between the throttles and the steering wheel will maintain course and speed most of the time...
