It currently operates on the Firth of Clyde running a year-round, high-frequency vehicle carrying service between Hunters Quay, near Dunoon, and McInroy's Point, on the outskirts of Gourock in Inverclyde.
[1] Three car ferries operated by MacBrayne's were all side-loading and not suited to carrying the sharply increasing growth in tourist traffic or commercial vehicles.
With the help of an HIDB loan a landing craft type vessel, Isle of Gigha was constructed and started operation in the middle of the seaman's strike.
The service provided a new roll-on/roll-off facility, operated twice as frequently as the existing boat to Islay, and offered lower rates without the benefit of subsidy.
It was immediately successful not only in taking the traffic which had formerly used mail or cargo services but also in converting much of the bulk trade which had formerly travelled in "puffers" to using trailers, thus saving on time, handling, breakage, pilferage and port dues.
He opened depots near both ferry terminals so that trailers could be moved on and off the vessels quickly without drivers and tractors units having to cross with them.
[1] At the beginning of 1969 the Port Askaig (Islay) – Feolin (Jura) service began – a high frequency service across a short stretch of water with a landing craft type vessel (the Isle of Gigha now modified and renamed Sound of Gigha, capable of carrying the largest commercial vehicle permitted on the road, or six cars).
Jura was now served by three through sailings a day instead of three per week and both islands could now enjoy things which had hitherto been luxuries, like fresh fruit.
The Sound of Islay however, under Captain Alister Meenan, took over the Kennacraig - Port Askaig route offering, for the first time, a reliable and punctual service.
[2] Traffic developed rapidly and in August 1974, the former Isle of Wight ferry, MV Lymington joined the service as Sound of Sanda.
[4] In early January 2010, the company announced that it was to commence a high frequency, low fare route between Ardrossan and Brodick in direct competition to publicly owned Caledonian MacBrayne.
They stated that they were planning to build a new vessel with a carrying capacity of 400 passengers and 70 vehicles and services were expected to begin in 2012.
