If feeling ill look at the horizon and not at the bottom of the boat. I have advised quite a few anglers who feel queasy on board to drink diluted orange juice, and been told it works quite well. If you are being ill, you must remember to try and keep eating. Even after you have ground baited the area, your stomach is empty the feeling of seasickness does not go away, and you could do yourself damage. This brings me onto another essential item you will need, your bait, no not the bait you put on your hook but the bait you feed your face with.
Wrecking is hard work, it can also be miserable work if the conditions are wet and cold.
There is nothing better than a hot drink and a sandwich to perk you up. Always take plenty to eat and drink, even if the boat provides drinks. My favourite sarnies are egg, tomato mashed together with cucumber, and onions, sprinkled liberally with paprika. Lovely tasting and ensures you get plenty room on the boat. Now down to the nitty gritty , the tackle.
