Take a life jacket. One that inflates when you need it to.
Dont get pissed, its a good way to die on a small boat.
Don't throw an anchor overboard unless you are very sure it will reach the bottom.
Take a mobile in a waterproof bag and leave details with someone when you will be back.
Have a graet time. I love sea fishing and have done it for a job in the past.
But mehearty be ware, dick about too much and you can drown very very quickly.
Fish near rocks or harbour walls, known wrecks, you are more likely to catch something.
Catch fresh mackerel, fillet, roll in beaten eggs with salt and pepper, roll in oats, fry and eat with brown bread, heaven on earth.
I fish off a sea kayak these days, oh the peace and joy.
