Being on a boat is perfectly safe during pregnancy, as long as you consider some common sense precautions. Make sure you have a properly fitting life jacket and a driver who is sympathetic to the fact that you’re pregnant, make sure you stay close to shore and avoid boat-centric water sports like skiing and wakeboarding.
Early in pregnancy, you may already be feeling nauseous, and for many people, being out on the water can exacerbate this feeling. So stay well hydrated, and avoid a boat ride altogether if you’re already super sick.
Also, make sure you aren’t planning an unsafe boat outing. For example, a deep sea outing with projected rough seas could increase your risk of falling in the boat or falling out of the boat. Water skiing and wakeboarding are generally frowned upon because you can hit your belly pretty hard on the water if you take a fall.
If you’re near term, avoid boat rides that are hours away from shore. If you were to need medical assistance, it’s best to be able to get to the dock somewhat quickly.
Most pregnant people who want to enjoy a boat are just cruising and spending time with friends and family. In general this is super safe. And don’t worry too much about a few gentle bumps or waves along the way. You and your baby will be fine.
