We are writing to give you notice regarding a change in our vessel schedule for the next four voyages. There is no change in frequency or transit time between Houston, Texas and San Juan, Puerto Rico.
We are just adjusting our days of the week for departures and arrivals for voyages 326 through 329.
We are making this adjustment because our home port in Houston, Jacintoport, is making a major investment in its terminal by adding two new state-of-the-art cranes as well as implementing a Terminal Operating System.
Schedule Change — Voyages 326–329
This interim change will not impact transit time or frequency but will alter the days of the week for cargo cutoffs and cargo arrival.
Southbound — Houston to San Juan
| Event | Previous Day | New Day |
|---|---|---|
| Houston Departure | Wednesday | Saturday |
| Southbound Cargo Cutoff | Tuesday | Thursday |
| San Juan Arrival | — | Thursday |
| San Juan Cargo Availability | — | Friday |
Northbound — San Juan to Houston
| Event | Previous Day | New Day |
|---|---|---|
| San Juan Departure | — | Friday |
| San Juan Cargo Cutoff | Tuesday | Wednesday |
| Houston Arrival | — | Friday (following week) |
| Houston Cargo Availability | — | Monday |
Why We’re Making This Change
Jacintoport is investing in two new state-of-the-art cranes and a new Terminal Operating System. These upgrades are designed to provide faster turnaround times and increased reliability.

Thank you for your patience as we work to build a more resilient shipping network.
