Actually, Sony makes a pretty decent digital camera, and the picture quality off of them is excellent. They're also quite easy to use....I've given three of them to family and friends as gifts. For the more advanced enthusiast, you're definitely better off going with a DSLR from either Nikon or Canon. The one real objection I have to the Canon equipment is the durability of their consumer end equipment.
I've been a photographer for over 20 years, and have used the Canon EOS, Nikon Fx, Leica, Hasselblad, Mamiya, Pentax, Sinar and Horseman equipment.
The Hasselblad equipment is beautiful, but way overpriced for what you're getting IMHO.
The consumer Canon stuff is junk—you can actually flex the camera body enough to see the twist—but their pro stuff is good.
The Nikon stuff is excellent—for years they were playing catchup to Canon in the high-end digital market, but the D80 and D200 have fixed that for the most part.
I love the Mamiya medium format gear, but it's way to big and heavy for a boat. Same with Sinar and Horseman—large format isn't really an option on a boat.
Leica makes beautiful gear, but also overpriced IMHO. My only Leica is an ancient M3 that I got at a yard sale for $100.

Getting lenses for it has been very painful.
One camera I'd love to get my hands on is a Nikonos RS, but they're very expensive and fairly rare at this point.
Alex-
I don't think she would have scalped you in your sleep...if she scalped you, you could still mooch her Nikon from her... she'd probably cut off your hands or stab you in the heart...depending on how much she liked you....and whether she wanted to keep you around for other things.

I will probably have to downsize my camera collection before I cut the docklines. They aren't very happy about just sitting in storage, and I have enough that bringing them all on a boat isn't an option.
