Of course you already know how to sail your boat very well, but if you do not have that knowledge then we recommend training from https://yapp.pro/. Of course, the level of yacht preparation depends largely on the complexity and range of the chosen route.
Exterior inspection of the vessel and its rigging
Before you launch your boat the first thing you should look at is the integrity of the hull and rigging. If the yacht is a sailing boat, make sure the rigging is set correctly, mast is straight and sails are perfectly set, otherwise any deviations and defects will affect maneuverability and speed, which will be very problematic to manage.
Standing rigging should be firmly and securely fastened, anchor and mooring equipment should be securely fastened. Go down into the hold and inspect it for leaks. While you are in the hold, check the water tanks and pumps. Pay attention to the pumps - see if the hose filters are clogged. Make sure the pump is pumping.
Checking systems and equipment
To avoid unpleasant surprises, before the boat leaves the shore test the onboard electronics on the board by switching on all the instruments on the board one by one. Start the navigation system - a significant discrepancy between the magnetic and compass readings may indicate that the autopilot is out of calibration.
Check if the devices are working correctly: echo sounder should show the depth, anemometer - wind direction and speed.
As darkness falls, take a walk around the deck and pay attention to the boat lighting. Make sure all contacts are insulated and protected from water, and that the batteries are firmly secured.
Check the lights in the cabins and galley, see if the navigation and position lights are on, and make sure all members of your crew know where the switches and switches are located.
