An expedition, not a cruise, with many scientific experts on board to help, talk and lecture, with their own areas of expertise.
Particularly good if you were interested in bird and sea wildlife and the geology of our country / islands.
We were travelling to some remot'ish islands and taking into account all safety issues they managed to get us to land at all the destinations. All bar about 3 were tendered using the RHIBs. Care was taken at St Kilda due to the swell in the bay but after careful exploration by some (while we in the meantime encircled the archipelago in the main boat) the swell reduced & we were tendered ashore, albeit for a timespan slightly less than originally planned. Not a problem, just great to get onto the island, Hirta.
