Will Sturgeon, his wife Tess and Seadog Sydney live aboard their Crown 39, Summer Sky in Vancouver, BC. I was interested in what modifications they have made to their boat in order to accommodate living aboard. Will was good enough to send me the following description and photos:

As for changes to Summer Sky, we didn't do much for the first three years after we purchased her in 96, except replace the dodger, anchor, and install a diesel heater and a two blade maxi prop. She was our sixth boat, and the plan was for a bigger and more offshore appropriate final upgrade later, perhaps an Ingrid or Tayana, as I mentioned. Well, Life gets in the way sometimes, and one has to make the best of what is really not such a bad situation  living aboard on a pretty good vessel already. Once the mental sea change transpired, the changes came fast and furious. 

• Lofrans Tigres 1200 electric windlass, with foredeck and cockpit controls. (Ideologically, as I love to sail in and off the hook, I wanted a manual version, but when the small windlass that came with the boat finally died, I figured I might as well use the existing wiring, so opted for the electric with manual override. THEN I discovered that the existing wiring was too small, so had to replumb new stuff anyway!) 
• Moved 33lb. Bruce and 100 ft. high test chain to stern, installed stern roller. Purchased 35lb CQR and 255 ft BBB chain for new windlass on bow. (Both with additional rode, of course.) Cockpit enclosure, weather cloths. 
• Wrapped wheel with leather cover over foam. 
• Custom instrument panel over Nav table. 
• 12v/110 NovaCool fridge under nav table. (removed 2 drawers that were there and repositioned under new book case outboard/abaft nav table.) 
• New cupboards adjacent galley stove (and Nav table, as just mentioned.) 
• 600 watt inverter. 
• 4 125 amp hour golf cart batteries in two banks  500 amp hours available. 
• Link 10 battery monitor. 
• Three stage constavolt. 
• Dickenson Newport diesel heater, as mentioned. 
• Maxi prop, as mentioned. 
• TV/VCR Microwave 
• Laptop and printer of course, as I write, but with Visual Nav series. 
• Custom cupboards in forepeak. 
• Custom shelves in quarterberth for tools storage.
