Rates for traditional panamax-size boxships are being given a new lease of life.

Charter rates for "classic" panamaxes in the 4,000-teu to 5,100-teu range have risen by $2,000 to more than $10,000 per day in recent weeks as well as the vessels being fixed for longer periods, brokers said.

Recent fixtures point to the classic panamax market as having risen to its highest level since last year.
