Agents are not required for all foreign-flagged boat less than 50 TRB (Gross Registered Tonnage)
On August 8, 2017, The Government of Ecuador published in the Oficial Registry Nº 53, the law whereby the procedure for clearing in and out of Ecuador:
For foreign vessels, which are for private use, not for commercial purposes and less than 50 GRT, the Captain, ship-owner or owner may represent the ship as its shipping agent, who will coordinate directly with the Harbor Captain’s jurisdiction, for compliance of the norm and payment of respective fees. Puerto Lucia Yacht Club will liaise with the local authorities.
Vessels may stay in our marina up to one year. Ecuador does not require a Visa for visitors or tourists from most countries. Minimum ninety-one days, maximum one hundred and eighty days in each period of twelve months (calendar year), counted from the entry of the tourist to Ecuador. http://www.cancilleria.gob.ec/
It has taken a lot of effort and lobbying from Puerto Lucia Yacht Club to make clearing a streamlined process, saving the cruisers time and money.
