In Santa Crux de Tenerife http://www.inprecasa.com/
Took cheapest option of taking the 4 person Liferaft up on the Tranvia (tram), stop University Hospital, take previous servicing papers, as they primarily deal with comercial Ferries, and as we rely on our Grab Bag removes cost of First Aid kit etc. Price came in at twice + the price of http://norwestmarine.co.uk/
in Liverpool, but far better than some other prices quoted in the Canaries
