#CorkHarbour - An unusually high concentration of Mainport Group vessels among them a seismic-survey ship made a maiden Irish port of call to her owners homeport of Cork Harbour this morning, writes Jehan Ashmore.

Afloat had monitored the arrival of Mainport Pine, the most modern of the Cork based company fleet that docked just before 09.30hrs. Mainport Pine of 1,659 gross tonnage was delivered in 2014 and is the second of a pair of commissioned Malaysian built seismic-survey vessels.

These high-tech sophisticated vessels collect information about the subsea and so are vital for the oil and gas industry. The pair are used on the charter market by the exploration /energy companies.

Almost a year ago Afloat reported on sister Mainport Cedar completed in 2013, had previously also made a homecoming debut to Cork.  At the time the vessel was undergoing maintenance in between a repositioning voyage that led to a contract for the oil industry based in the Gulf of Mexico.

Mainport Pine had departed Bergen, Norway and Afloat yesterday had also tracked the ship while offshore of Wicklow Head when bound for Cork.  It was at the city's central quays that this morning saw the ship berth astern of a fleetmate, Mainport Kells. This seismic-chase vessel is designed to intercept any approaching vessels which could damage cables being towed or installed on the seabed.

The pair are togther berthed at North Custom House Quay.

Downriver one of Mainport's tugs Celtic Isle which in recent years was transferred from Shannon Estuary operations at the Port of Foynes, is berthed at Cork Dockyard.

Asides towage duties, Celtic Isle is employed on serving the requirements of the Kinsale Gas Field along with Ocean Spey which was acquired last year. This standby and supply vessel with handling handling capacity is this morning offshore of the two gas platforms rigs in the Celtic Sea.

#PORTS & SHIPPING - Cork based marine services company, Mainport is investing $36 million (€27.6 million) to build three supply vessels which will support seismic survey ships searching for oil and gas deposits.

The bulk of the financing for the construction of the newbuildings has been provided by Dutch bank ABN Amro, with a syndicate of Irish investors assembled by Westboro Finance in Cork providing $5 million in mezzanine, or short-term, financing.

The three ships, which will provide support services for an unnamed client carrying out off-shore seismic surveys around the world, are being constructed at Shin Yang Shipyards in Malaysia, and will be delivered in mid-2013.

The Star keelboat is a 6.9 metres (23 ft) one-design racing keelboat for two people designed by Francis Sweisguth in 1910.

The Star was an Olympic keelboat class from 1932 through to 2012, the last year keelboats appeared at the Summer Olympics at which Ireland's representatives were Peter O'Leary and David Burrows.

Ireland has performed well in the class internationally thanks to some Olympic campaigns including a bronze medal at the Star World Championships in 2000, won by Mark Mansfield and David O'Brien.

The boat is sloop-rigged, with a mainsail larger in proportional size than any other boat of its length. Unlike most modern racing boats, it does not use a spinnaker when sailing downwind. Instead, when running downwind a whisker pole is used to hold the jib out to windward for correct wind flow.

Early Stars were built from wood, but modern boats are of fibreglass and carbon construction.

The boat must weigh at least 671 kg (1,479 lb) with a maximum total sail area of 26.5 m2 (285 sq ft).

The Star class pioneered an unusual circular boom vang track, which allows the vang to effectively hold the boom down even when the boom is turned far outboard on a downwind run.

Another notable aspect of Star sailing is the extreme hiking position adopted by the crew and at times the helmsman, who normally use a harness to help hang low off the windward side of the boat with only their lower legs inside.
