You'll upset the natives calling them loCKs they are loCHs
The obvious options would be Loch Lomond, or Loch Ness (and the other lochs that link to form the Caledonian Canal). Most other freshwater/inland lochs are going to be fairly small for any sort of cruising. Many of the sea lochs are also very sheltered (and can be more so than 30 miles of fetch down loch lomond) - but it depends if you can convince the wife. Depending how attentive she is she may not even realise it is the see e.g. Loch Sween where the tidal range is fairly low!
The only other inland loch that springs to mind where pleasure motor boats are common is Loch Tay. Other than that most motor boats will be for sailing club coaching/safety or fishing.
Anywhere picturesque will have cottages to rent. All the big lochs (lomond, ness, tay) will provide ample photo opportunities - but could be a bit cliched depending what you want.
