Marina Hemingway, run by the governmental Cubanacán, is Cuba's largest marina with an official capacity of up to 400 vessels. In reality, there are closer to 100 slips that are usable - the others needing repair and installation of basic marina services (power & water).
Mariners will find the entrance to the marina challenging and should only be attempted in relatively calm conditions. Vessels must navigate a very narrow channel with shallow coral on either side to enter Marina Hemingway. Nighttime entry is particularly dangerous and should be avoided as the channel marker lights are difficult to distinguish from city lights in their background.
Vessels approaching the entrance to Marina Hemingway should hail the port captain on VHF channel 77, or over SSB 7462.
