Returning to the question of sea sickness (with apologies to anyone having dinner or tea) but I found three ways of overcoming the dreaded condition.
1. Stay on deck and watch the horizon. Helps the inner ear and eye to give the brain the same message with regard to your orientation.
2. Lie down. same reasons as before.
3. Retire to the bar. (Usually in or about the centre line of vessel so previous post re being in the centre of the boat applies - but if enough amber liquid is consumed who cares! )
And don't forget you guys - the old steamers did not have stabalisers!
