Sorry only had half the story earlier according to the bloke that lives in a motorhome on the beach he said they put nets out around all the rocks in a 'v'
shape then spent the day trawling up and down then collected there nets later on,they did this 3 days in a row. They were coming right in 100-150yds off the shore! Looks like they were after the bass.
Doesn't sound great but will be giving it a bash down there later tonight. Least I have a excuse ready if I blank!
