Important Information

  • Public transportation options are available nearby
  • Not recommended for travelers with poor cardiovascular health
  • Travelers should have at least a moderate level of physical fitness
  • Vegetarian, vegan or gluten free option is available, please advise at time of booking if required
  • Please bring towel, swimsuit, sunscreen, sunglasses and hat. We also recommend a jumper in the cooler months.
  • To participate in the activity of snorkelling, you must be confident in the water with the capacity to swim unassisted. If you are a poor swimmer, you may not be suitable to snorkel in the open water. Not all passengers will be suitable to snorkel, and our experienced crew have the discretion to advise against snorkelling if deemed “not suitable for the activity”. This is for the safety of the passenger. Please be advised snorkelling can be a strenuous physical activity, even in calm water and that older people are at an increased risk of death and/or injury due to a higher incidence of medical conditions made worse by physical exertion, such as heart disease and stroke. All passengers intending to snorkel will be asked to complete our Medical Declaration for Snorkelling form. Our experienced crew will discuss any issues relating to medical conditions and swimming ability. Sailaway reserves the right to decline any passenger from participating in snorkelling if we are concerned about your health condition and/or swimming ability. This is for your own safety, please listen to the advice of our experienced snorkel guides to ensure the safety of our guests.
  • Our Sailaway vessels are luxury sailing catamarans and we offer a pure sailing experience. This means the vessels travel in open seas and will move around whilst under sail. The decks of the vessels are multi levels and can be slippery when wet. Passengers must have good mobility to safely move around the vessels, step onto the glass bottom boats (if applicable) and get in and out of the water via the ladders on the back of the vessels. Unfortunately, we do not offer wheelchair access due to the layout of the decks and saloon areas. Our tours are adventure experiences for active travellers. Please choose your tour carefully to ensure it is suitable for your experience, age and physical health.
