The boat may be capable in its design, but...
do you have working nav lights?
Calculated fuel usage?
Checked for fuel and water?
Spare fuel filters, oil filters on board?
check the weather forecast?
lifejackets, flares, liferaft?
Navigation instruments all working and you understand how to use them?
GPS or chartplotter available?
VHF working? call the coastguard for a radio check to be sure...
Have you planned a passage? plotted a route on the chart or plotter?
If you are drunk then don't bother - don't drink and drive!!!
Alternatively, go out earlier and anchor somewhere for the night. (Have you got an anchor light? Is you winch/rope/chain/anchor all working ? )
All basic stuff for going to sea, even if it is only a short nip out and in, the best sailors are prepared for the worst.
