Navios Maritime Partners announced on Tuesday that it struck chartering deals for five of its panamax containerships worth an aggregate of at least $220m.

The ships are the 4,250-teu Navios Vermilion (built 2007), Navios Miami and Navios Destiny (both built 2009), and the 4,730-teu Navios Nerine and Navios Magnolia (both built 2008).

The Angeliki Frangou-led company — a spin-off of Navios Maritime Holdings — did not announce which charterer agreed to fix the vessels.

Their new employment will begin at various points during the second half of the year.

The vessels' new freight rates are staggered, starting at a steep $54,313 per day in the first year and then decline to $45,425 per day in the second and $23,972 per day in the third.

These earnings are far above what the ships have been earning in their current charter contracts, which expire between September and December.

According to New York-listed Navios Partners’ latest financial results, the Navios Vermilion is currently chartered at $21,330 per day. Brokers said Cosco Shipping Lines has fixed the vessel.

The Chinese carrier is also the last known charterer of the Navios Destiny and Navios Magnolia, and each of them earns $18,022 per day.

The Navios Nerine currently earns $24,125 per day.

Navios Partners owns and manages 51 bulkers. The company's merger with Navios Maritime Containers at the end of March boosted its containership fleet to 38 ships.

Several of these vessels are financed through sale-and-leaseback transactions. Those include the Navios Vermilion and the Navios Destiny, which are reportedly owned by Minsheng Financial Leasing.
