Get Offshore!

Go on, get out on the water with us. Where you’ll experience the most exhilarating – and unique challenges. Nothing compares to the feeling of being out at sea, right there in the elements. Take on challenging nautical training in a voyage on one of our vessels.  Cadets will pull together with other cadets to safely navigate Britain’s coastline. This is teamwork taken to another level.  

Offshore operations give cadets a great opportunity to develop their nautical knowledge and skills, complementing the nautical training they gain at unit level. The Sea Cadets have three classes of vessels, all of which are capable of coastal/offshore passage making. 

For each cadet the target should be to spend at least one week afloat offshore in a power vessel, and another in a sailing vessel, during their time in the Corps.  Unit staff should carefully select the vessel best suited to the needs of the cadet. 

Below you can read about each vessel and see the voyages for 2013 plus find out more about what cadets can learn. Please read on!

Our offshore vessels operate over a 9 month season (Mar – Nov) and are programmed to make port calls all around the UK to facilitate access by all Sea Cadet units.  The intent is to maximise berth utilisation, accepting the constraints of the accommodation available and the need for all to be physically capable of sea service in these relatively small craft. Their task is to provide sea experience and training for both SCC adults and cadets. To this end, those in command of vessels are tasked to ensure that the training of both adults and cadets is progressed during each voyage by arranging both formal and informal training sessions as part of the daily routine. The aim must be to ensure that as far as possible everyone ends the voyage better qualified than when they started.
Vessels may  also be available to NCF cadets and to other uniformed youth organisations and, on occasion, to the RN and RNR.
