Hi snagmagnet!! I saw that last week too! My first thought was the same as yours - wow what a fishing platform!!!!! According to my son it is to do with the dedging up of the sand a little way of-shore and putting it back on the beach. Lousy news for the fisherman with all that disturbance etc.,but, in the short-term it is supposed to be good (?) for the holidaymaker, and tourists who visit the nearby resorts.
What really upset me was the sheer number of good quality fish, especially thornbacks,that were dredged up and pumped out and dumped dead on the beach. Come to think of it, I still can't work out why the powers that be chose to do away with the breakwaters a few years ago anyway.
Now I've got my resentment out of the way I would like to add that I am planning a trip to Moggs Eye in the next day or so and if I feel up to it I'll have wander down the beach and do a bit of nosing about!! I'll let you know if I find out.
THANK COD FOR FISHING!!
