Had a similar problem, decided to do it myself, took photos at each stage, the marina let me have a room where I left it overnight fully inflated, getting it back in the box the difficult bit, complete deflation requires a good pump to get ALL the air out. I checked the cylinder weight in local surpermarket on professional scales, was perfect.
There are many threads here on doing it yourself if you feel confident to.
Sarnia, Thanks for your help. However, although it is attractive, I will not have time to do the service myself, so I was hoping to find a company in Lanzarote to do the liferaft service.
