I get most of my Mackerel off Dunure / Ayr.
They are there in abundance during the summer but most are on the small side.
You do get bigger ones but they are in the minority.
My old man adores Mackerel and smokes them and freezes them by the barrow load.
My mother is not so keen on the smell they resonate throughout her house tho.
South Ayrshire Council put a huge skip on the boat launch ramp onto Ayr beach at Ayr India.
The council use a tractor to dredge / clear rubbish from the beach then load it into the skip.
No one can get their darn boats launched now as the skip is blocking the path alo g tge ramp onto the hard of packed sand.
As top of the beach is deep (sinking) white powered sand so accessing the beach elsewhere is off limits.
Queue the boat in a bag again - carry it onto shoreline, roll out, blow up and go fishing.
I can think of many applications where the small slat floor Sib will get used over its larger trailer stricken brother.
I can also think of many applications where the larger Sib will get preference too.
