One hand for the boat at all times. No shoes on board. No cardboard below decks - empty provisioning boxes up top and get rid of them - lots of times the delivery people will want them back! This will help avoid unwanted "guests" known as roaches <img src="http://www.traveltalkonline.com/forums/images/graemlins/Grin.gif" alt="" />

If it can overboard, it will - warn people about sunglasses (or worse - prescription glasses!) falling off faces - secure them around your neck - clip on straps for baseball caps, etc., iPods, iPhones, etc etc. Avoid spray-on suntan products that typically get everywhere but on the body - but make sure everyone IS aware of how strong the sun can be so they don't burn and ruin a few good days! This is all that's popping into my head but I know there's more - along with what you've already got - and, of course, the all-important "captain is in charge", which has also been covered.
