Clean up after yourself,
Best tip for getting along in a group, don't leave your stuff where it will impact others, if you use sink etc. wipe it down after, put whatever you touch back where you found it or where it belongs, if something obviously needs to be done & you can do it, do so, cleaning, trash, rust removal, polish etc., treat the boat like fragile gold. Most people don't enjoy others watching them work so if someone is doing something lend them a hand when possible. Rinse/wash dishes, glasses after you use depending on boat's practice, find out what the boat does about what you use freshwater for and what you use salt, people have different levels in this regard and if freshwater is tight it's not good if you are the only one spitting it down the drain brushing your teeth.Some personals, take them or leave them: Cooks don't wash dishes, if your not busy during meal prep. ask if there is anything you can do to assist,clean up for the cook as he works if possible, if someone has to set the table the same way everyday don't wait to be told. Don't ever stand with the icebox lid open figuring out what you want, that little bit of cold air in there can be the most valuable commodity on the boat, Captain get ugly if his beer get warm. Don't discuss politics or religion in a group except in vague terms then change the subject. Captain has lot of crap that goes with the title, when it's just you & him he may be Tom, Dick or Harry but when others are around throw him a bone and call him "Cap". Try not to make him repeat himself, but make sure you are clear about what he wants done, when he "asks" you to do something, jump to it. God gave us 2 ears and 1 mouth, try to use them at the same ratio.
