We went in August, entire N Coast, vessels required to get BIS
Permit approved, then submit float plan and get USCG approval. Will need to list a General
License reason in your BIS request with full details.
Clearance in and out at every PORT, virtually impossible once there to lower your
tender to
water, must stay on big
boat at all times except when in totally uninhabited areas of Jardines del Rey, or similar.
Only 4 places on N Coast from Havana to East tip, to get
Fuel, Havana, Varadero, Guillermo (Jardines area), Puerta Vita.... Friendly people, however nowhere near ready for FL boaters. The "Marinas" listed above only have a couple slips along seawalls available on a Med-Moor... except Varadero (all inclusive Tourist Beach Hotels area) with great modern Marina, but limited on anything to do but visit the inclusive hotels... or Havana/Hemingway.
No reason to "rush" down, it's not possible to change Cuba quickly, and there is a long way to go to get to what FL boaters will desire for a return trip.
