Myself and son in law wanted to obtain a licence so we could hire a boat for pleasure trips whilst in Spain.
Having limited Spanish I was careful to scour the numerous companies offering the initial navigation module.
Cenautica Alicante were not only the cheapest we found they were the best, from initial cobtact with Caesar professional and helpful, assisting with the required medical, in addition, the overall cost was less than many others.
The course itself was fun and informative. Although you can hire a boat without the course, I would advise not doing that.
Worth special note are the staff that made the process easy and enjoyable, Caesar in the Madrid office, Barbara in the Alicante office and the course lead Miguel, thank you all, I have no hesitation recommending Cenáutica to others.
