WTT: 15" MacBook Pro For Newer Yak

Have a really nice MBP 15". Does not get used at all in our home. Bought in mid '12 for wife and kids. Thought wife would like its ease of use but didn't and kids prefer tablets. So, it just sits. Fresh new Yosemite install.

Looking for a yak I can use in Santa Cruz, Capitola, Monterey waters. Delta and local lakes. Currently have an older Ocean Kayak Scrambler XT but want something a bit newer. 

No brand preference really, just nothing cheap or thin hulled boats.

Want it to be stable to fish from and nothing over 14' please.

Thanks!
Daniel
