Hey if you could get the blue one for around $100 to $150 bucks, then transfer any components needed (like the mirage drive, paddle, etc) to this one ( http://fortmyers.craigslist.org/lee/boa/4191548953.html
). You would have a pretty nice adventure for around $600 to $700 bucks, if the yellow one is ok and you could get it for $500 you would be set. Of course the yellow one would need to be inspected carefully, it looks like it was scavenged for parts, but it doesn't look too bad by the picture. Both are in the same area. The yellow one appears to be sitting at a dealer (likely an ex dealer). Especially if the yellow one is newer and there is some warranty left, it would be a sweet deal for someone wanting to take a little risk. Considering a new Adventure is $2100.
Actually the yellow one is an adventure Island (with no AMA's) I'm guessing 2009 or 10 (it has the newer style mast holder I think). I'm sure there are tons of T/S rudders floating around, I know I have one in my garage from my TI, that would likely bolt on.
You would need to verify that the HID number is clear, and that this was not a dead warranty replaced hull (supposed to have been destroyed), that has been repaired or salvaged) BIG RED FLAGS.
This is all assuming that mirage drive is at least salvageable.
I remember a couple years ago an ex Hobie dealer in Crystal River (FL) offered me a killer deal on a couple adventure Islands that they never sold, they were several years old at the time but supposedly still new. So there are deals out there if you know where to look I guess.
A lot of flim flam sheisters out there on craigs list.
