Hi Klunk, as Brian says there is a club in Torrevieja, about an hours drive south of Benidorm. We meet on the second Sunday of each month at 10 30 am. I donīt know if thatīs any help as Iīm not sure when youīll be in Spain.
There is also a club in San Vincente del Raspeig, just north of Alicante, Iīve visited a Tug towing event there, but donīt have any details of the club.

And lastly, if you happen to like trains as well, there is a live steam railway 5 mins from Alicante airport.
some videos are on you tube, search for Torrellano steam railway
I would say that our model shops are typical of most places, not brilliant for model boaters, and quite naturally leaning towards ready made stuff so they can make a living.
Not such a modeling desert after all!
