CloseDon't Let Mal de Mer Ruin Your Dive
At Rainbow Scuba Hawaii, we want every guest to have an unforgettable underwater adventure. However, even the most experienced divers can occasionally fall victim to motion sickness (Mal de Mer). The rolling swells of the Pacific, while beautiful, can cause nausea and dizziness that might prevent you from enjoying the Sea Tiger Wreck or Horseshoe Reef. Understanding how to manage these symptoms is key to a successful boat charter.
Recommended Medication: Bonine
Through years of operating dive charters in Honolulu, we have found that Bonine (the brand name for Meclizine) is exceptionally effective for our customers. Unlike some older formulas, it is less likely to cause the heavy drowsiness that can interfere with your dive safety and alertness.
Suggested Protocol:
For the best results, many of our divers follow this schedule:
- One pill the night before: This helps the medication build up in your system while you sleep.
- One pill the morning of the dive: Take this at least one hour before boarding the boat.
Everyone who has followed this "double-dose" timing has reported excellent results. However, please note this disclaimer: As with any medication, please consult your doctor or pharmacist prior to use, as individual reactions and dosages may vary. You can find more technical details at drugs.com.
Natural Tips for Staying Settled
Beyond medication, your behavior on the boat can significantly impact how you feel. If you start to feel "queasy," follow these pro-tips from our crew:
- Look at the Horizon: Fix your gaze on a stationary point on land or the distant horizon. This helps your inner ear and eyes sync up.
- Stay Mid-Ship: The center of the boat experiences the least amount of "pitch and roll." Stay on deck where there is fresh air—avoid the cabin or the head (bathroom) if you feel ill.
- Hydrate and Snack: Avoid a completely empty stomach, but don't eat a greasy "plate lunch" right before boarding. Light crackers and ginger ale are great options.
You can purchase Bonine or generic Meclizine at most Walmart locations, ABC Stores in Waikiki, or local pharmacies for approximately $5.00 to $10.00.
Ready to Dive?
By taking a few proactive steps, you can ensure that your focus remains on the incredible marine life and crystal-clear waters of Oahu, rather than the motion of the boat. We look forward to seeing you on board for a comfortable and exciting dive day!
