Yes Mary, the teakettle (a cold one I hope) and cushions are no worry. Floor panels, batteries and whatever is stored under them are something else. Like e.g. the owners diving gear. Wonder how a capsize would be if they were in the saloon: http://catamaransailing.com/images/voyage440ext.jpg

Sure I would want my cruising boat to be liveable if inverted. Staying dry is a prime requisite for surviving in cold water. I would also like at least a cutaway escape hatch. Not much use in being tethered to the boat unless you are able to enter it after the capsize. Diving in survival gear trough all the lines and possible fouled rigging to enter the boat dont sound like a good plan.
