Yes, in most cases you will need to pre-book a berth in a marina – for this reason travel itineraries will often be planned well in advance. That said, there are often many options available without booking depending on the time of year and the location. Anchoring out is also another option, especially in smaller ports where there may not be berths big enough to accommodate larger vessels. Many owners also invest in purchasing or leasing a marina berth in their port of choice.
