No sailing in the canal - motor
The canal authority has a website that is very good and explains everything.
The overall cost will be highly variable depending on whether you use an agent or not, have to pay for line handlers or get free friends, have to rent fenders and lines or already have them, choose to stay at a marina during the 5-7 days of preparation or anchor
out in the harbor, etc.
Plan between $700 and $4,000.
