Several small Greek shipowners have been shifting their focus from handysizes to supramaxes with moves to renew and expand their fleets.

The most high-profile example is Diligent Holdings. Originally a handysize bulker specialist, it has been second only to Star Bulk Carriers among Greek companies that have scooped up supra­max tonnage in the secondhand market this year.

Diligent is not alone. Two Greek companies are linked this week to the purchase of the Japanese-­controlled, 53,600-dwt Iyo Wind (built 2008).

Some brokers believe TST International bought the vessel for about $10.3m. Others, however, ­report that Greek peer Thalkat Shipping snapped it up for $10.45m.

Managers at TST did not respond to a request for comment and Thalkat executives declined to comment.

Both companies were predominantly handysize and handymax players that have been gradually shifting their focus to supramaxes, the next-biggest size category.

Konstantinos Rokkos-led TST reportedly sold the 48,200-dwt Paolo U (built 1997) last week, for between $4m and $4.4m.

If the Iyo Wind purchase is confirmed, it would be TST’s first acquisition in almost four years. For Konstantinos Kladias-led Thalkat, it would be its first buy in nearly three years.

Another recent supramax buyer is Fortius Ship Management, a company previously known as S Frangoulis Ship Management.

Shipping databases show the Athens-based company, or its clients, as the new owner of the 56,000-dwt bulker Misato K (built 2013), which was renamed Aquarius. Brokers reported the Mitsui Engineering & Ship­building-­constructed vessel as sold in late June to unidentified Greeks at an undisclosed price.

Fortius was a pure-play handysize player before Dec­ember 2017, when it purchased its first supramax, the 55,900-dwt Neptune Pioneer (built 2007) and renamed it Icarius.

The company’s acquisition of the Misato K is its first move in the sale-and-purchase market since then.

Fortius managers declined to comment.

Another company that moved from handymaxes to supramaxes is US-based Delta Navigation Corp.

The John E Couloucoundis-­controlled outfit has emerged as owner of the 56,800-dwt Mia-S (built 2010), which Germany’s Reederei Schepers reportedly sold to un­identified parties at the end of July for $10.2m. It has been ­renamed Tanzanite.

The purchase of the Mia-S marks Delta Navigation’s return to dry bulk shipping more than a year after it sold the only ship in its fleet, the 43,200-dwt handymax Summer Wind (built 1995).

That vessel made headlines in 2014, when it collided with a barge in an incident that spilled 528 tonnes of heavy fuel oil into the Houston Ship Channel. A protracted legal battle followed, after which the owner of the barge paid a $4.9m civil penalty without ­admitting guilt.

Delta Navigation ultimately sold the Summer Wind in mid-2018, reportedly for about $5.3m. Some databases show the ship in the fleet of United Arab Emirates’ GTCS Trading, but others signal it is controlled by Linter LLC, a Russian company providing grain cargo services in the Black Sea.

A request for comment to Cleo­patra Shipping Agency, Delta Navigation’s Greece-based shipmanagement outfit, went unanswered.

And Greeks continued buying supramaxes with gusto last week, according to brokers. The 56,000-dwt Torenia (built 2007) reportedly changed hands for $11.3m; the 58,100-dwt Sea Iris (built 2010) for $13.2m; and the 58,800-dwt Carina Ocean (built 2009) for between $12.1m and $12.7m. All three are currently listed in Japanese-controlled fleets.
