Soon to be living aboard - need advice

[vook]

I plan to start living aboard a 30 foot sailboat in the coming weeks for the first time. I seek guidance. Is there anything that you all wish you had known prior to living aboard ? Do any of the clubs that rent slips have showers ? I'm on the San Diego Bay, is the water fairly active ? Does the boat tend to move around a lot on slips ? And what of heat ? Do most 30 foot boats (like Beneteau's) have heaters - hot water heaters ?

thanks !
