Porthleven, Cornwall in May

I will be staying in Porthleven for a weeek mid May. Can anyone give me advice on how and where to fish? I will be in a cottage to the east of the harbour, at the start of the long stretch of beach. I've had a look on Google Earth and it looks like the beack is pebbles and not sand but I'm not sure.

Advice on what to expect, where to go and what baits woudl be very welcome. Will I get away with a bass rod and 15lb line or do I need to go with a standard berachcatser and heavier line?

thanks

John
