Some of the books I have read recommend doing a quick boat check at every change of watch while on a passage. I think I will print this list out and add it in to the front of the log book:

• Check weather forecast – note current conditions and predictions in the log
• Check AIS and note any shipping in the area
• Check GPS/chart – course, speed, discuss any adjustments etc and note in logbook
• Check bilges and note any change
• Check hatches are closed
• Check seacocks and head
• Ensure gas is switched off
• Stow any loose equipment
• Check battery level and electronics – check navigation lights are working, fridge, etc
• Check engine area – belt tension, notice any smells or noises or anything unusual
• Check fuel and top up if necessary
• Look for chafe on lines and sails, coil and stow any stray lines
• Get binoculars and check rig
• Check steering/autohelm

Note anything of concern with a plan for monitoring and repairing if required
