I just bought a 30 foot islander a couple of months ago and have been living on it for about a month. Its more of a weekender rather than a liveaboard but I don't have much stuff so it works out ok. The one thing I am noticing is there is a distinct lack of storage space for things like clothes and stuff that you just don't want laying around. I am compensating by putting things in plastic bins and they work as an ok substitute for drawers. I have found several leaks in the rain and my stuff is at least dry that way.
I am finding I do a lot of shifting things from berths to settees and then back while I am trying to do things. But if you keep things organized and tidy it goes pretty quick.
If you have anyone come to stay ask them to bring a smaller soft sided suitcase. In 30 feet a big hardsided suitcase takes up pretty much an entire settee.
I am trying to plan out how to attack the leaks, add some more storage space and clean up cosmetic issues so I don't have to do things twice.
I was kind of worried that the alcohol stove would not work very well but I am finding it works just fine and I have no problems with the heat output of it. It boils water quick enough and I have had no real problems with it. I thought for sure I would be replacing it but I am finding it quite functional. The oven does not work so I can't comment on it until I get the tubes cleaned out but it I am using it to store my dishes anyway so am not in a big hurry to get it working.
