Boat sharing from San Miguel marina

Hi Does any one know of anybody who goes out fishingwith a rod and line from San Miguel Marina, who might be prepared to let me join them --
I have all my own tackle and would be pleased to share expenses or pay for the trip.
Anything would be gratefully considered.
I'd like to be able to fish near the shore before the water goes to 100 + meters deep,for rock fish rather than big game fishing,-that is not my thing.
I also like to fly fish when I can -but I have sort of given up on that on Tenerife now ( though I did manage to catch one dorada a year or two ago !!)
Fishing from the rocks is not very good and looses a lot of tackle !!

Any suggestions or contacts would be well received,
Thanks,,----( hopeful !) Fisherman
