There is little to choose in overall travelling time from Brodick in Arran to Glasgow, via Ardrossan or Troon. For the detail worked out, See:

Glen Sannox sailing from Troon means the same bus/car, shorter train, journey times from Glasgow and fewer bad weather cancellations

There is however a bloody good reason to prefer Troon based on the nature of their owners compared with the owners of Ardrossan, currently trying to screw the Scottish taxpayer for improvements they should have carried out themselves.

Ardrossan harbour is owned by Peel Group. They have a frankly sickening reputation. For example:

Controversies

Hunterston Parc

Campaigners objected to an LNG terminal Peel proposed for Hunterston Parc, Largs. The scheme included a combined cycle gas turbine power station; deep water port; facilities for oil rig decommissioning; a site for the recycling and storage of plastics, and dredging 2.4 million cubic metres of seabed. No environmental impact assessment was provided for the development.

Chat Moss

In 2011, Peel was accused of illegally extracting peat from its land near Salford. Following a 2012 Public Inquiry, Communities and Local Government Minister, Eric Pickles, backed Salford Council and Wigan Council in refusing further extraction at Chat Moss.

Biomass imports

In 2015, Peel established a biomass terminal at Liverpool’s Gladstone Dock for wood pellet imports from wetland forests in the Southern US. The pellets are then transported to Drax Power Station to be burnt. Campaigners objected to the greenhouse gas created in the process.

Car park fines

In 2021, multiple complaints were made about parking fines being issued by automated systems at Stockport Peel Centre even after motorists had purchased parking tickets.

Hunterston fatality

Peel’s Clydeport business was fined £5,000 in 2001 following a shore side fatality at Hunterston Terminal. The prior year it paid a £7,500 fine for an earlier incident.

Flying Phantom

In 2014, Peel’s Clydeport business pleaded guilty to health and safety breaches and was fined £650,000 following a triple fatality. River Clyde tug Flying Phantom capsized in the 2007 incident. Judgement found there had been systematic failure in risk assessments and safe systems of work. The charges also related to a similar incident involving the tug in 2000.

Fracking collusion

In 2014, high level collusion was found between Peel, police and a council. Documents revealed Salford Council, IGas Energy, Greater Manchester Police and Peel were sharing intelligence during anti-fracking protests at Barton Moss.

Congestion charge

In 2008, Peel was alleged to have covertly controlled a group that campaigned against a congestion charge for Manchester. It was claimed Peel feared a congestion charge would harm business at their Trafford Centre. Voters rejected introducing a congestion charge.

Excessive influence

In 2013, a report by Liverpool think-tank ExUrbe criticised Peel’s excessive influence on affairs and development in the Liverpool region, claiming Peel “blurred the boundaries between public and private interests”.

Tax evasion

In June 2013, Margaret Hodge, Chair of the Public Accounts Committee, accused Peel of tax dodging, and explained some parts of the group pay on average 10% Corporation Tax, and the more profitable ones paid no tax at all.

HMS Plymouth

In 2006 Peel required the Warship Preservation Trust to leave their Birkenhead premises. The trust was unable to find an alternative location for its vessels and shut down. HMS Plymouth remained berthed and Peel took possession. In 2014, campaigners disputed the legality of those ownership rights. The group accused the port of allowing the ship’s condition to worsen in order to make any attempt to move/preserve her appear unfeasible.

The campaigners were also critical of the way the subsequent sale of the vessel to Turkey for scrap was conducted.

Marine Terminals industrial action

In 2009, following redundancies (layoffs) at Peel’s Marine Terminals Ltd subsidiary in Dublin, and eight weeks of industrial action, strikers seized the cargo handling company’s control room. In co-ordinated action, Dutch FNV Union occupied the headquarters of sister subsidiary BG Freight’s head office in Rotterdam. Peel had hired private security firm Control Risks to police their Dublin facility.

MV Francop

During unloading of the MV Francop at Peel’s Dublin container port a sailor was crushed to death. During the 2018 incident a stack of four cargo containers was lifted off the vessel with a crane, resulting in the bottom container parting from the stack and falling onto the sailor. It was alleged against Peel’s subsidiary Marine Terminals Ltd that there was no appropriate planning, instruction, communication and supervision of the method to insert a missing deck lock under the bottom container in the stack.

Warrington traffic

In 2014, Warrington Council accused Peel’s Manchester Ship Canal of “self interest” and prioritising canal users rather than vehicle traffic in its operation of swing bridges over the canal. The council and canal operator subsequently announced they would work together. Residents were particularly concerned about the situation when the M6 Thelwall Viaduct had to be closed for maintenance, leaving no alternative route locally across the canal.

Land hoarding

In his 2019 book Who Owns England, Guy Shrubsole describes Peel as one of the ‘secretive’ companies that “hoards England’s land” and has made significant impacts, good and bad, on the environment and people’s lives:

Peel Holdings operates behind the scenes, quietly acquiring land and real estate, cutting billion-pound deals and influencing numerous planning decisions. Its investment decisions have had an enormous impact, whether for good or ill, on the places where millions of people live and work.

World Heritage loss

In July 2021, the World Heritage Committee cited the development of Liverpool Waters as a reason for the revocation of Liverpool’s World Heritage status.
