■Measures for seasickness


■Seasickness measures

* Meal

Avoid hunger and satiety when boarding, and eat a low-fat meal a few hours before boarding.

* Eyes

Make the most of your detailed work and equipment setup before departure as much as possible, and look on land and on the distant horizon on a boat.

* Vomiting

If you feel nauseous while traveling on a boat, go downwind, such as on the stern side.
Be careful not to fall into the sea.

* Boarding position

There is less shaking on the stern side than on the bow side, so let's board on the stern side.
Get on board in a place that does not absorb the exhaust gas of the boat.
For larger boats, board the deck in the wind, not in the cabin.
