Seasickness can impact even the hardiest people. We recommend that you consider taking a couple of Kwell tablets. Kwell are available from any Chemist, and you do need to read the instructions, as they are not suitable for everyone.
To get the best effect from Kwell, take one when going to bed the night before your fishing trip and then one when you wake up in the morning.
Interesting Fact: From many years at sea, I can state that Women handle seasickness better than Men (sorry Guys, but it's true)
