seaplane  fleet

There are  two (2) DHC-6-300 Twin Otter aircraft with WipLine floats in the  seaplane fleet with approximately 30 flights per day.   Seaborne is proud to operate this particular aircraft, a 19 passenger (our seaplanes are configured for 15 seats) Short Takeoff and Landing utility aircraft developed by deHavilland Canada.    This  type of aircraft is designed  to be a regional passenger airliner and Medevac aicraft.    The pontoons used for  water based departures and landings have  allowed a practical seaplane solution to thrive  in  destinations  all over the world that  benefit from convenient inter-island connections,  just like the Caribbean.   Read more about the seaplane fleet.

seaplane challenges

Did you know that seaplanes cost more than twice as much to operate  as land based aircraft?   Why? Because the salt and rough water take a significant daily toll on our aircraft! In order continue to fly SAFELY, which is our first priority, we must constantly overhaul aircraft and replace expensive parts.

Here are some numbers:

  • Aircraft overhauls (done every three years) run upwards of $1,500,000.
  • Parts, replaced multiple times daily, cost as much as $25,000!
  • Engines replacements are over $300,000!
  • Then there are the aircraft themselves, the Twin Otter – which now cost over $4,000,000 to put in service, twice the amount just three years ago!!!
  • Land based aircraft, engines, and parts, by comparison, last 15 years longer!!!
  • Now add the fact that the price of fuel has tripled over the past three years!
