Our Story: Aldenaire's 40 Years

Aldenaire Boat Tours has run the harbour since 1987 (that is nearly forty seasons), when Captain Ren Aldenaire bought a single wooden launch and started taking neighbours out to the seal colony on Sunday mornings. Today the fleet is four boats, but the trips are still small — never more than twelve guests — so everyone gets a seat at the rail.

What a morning looks like

We leave the quay at 9:00 sharp, motor past the old lighthouse and cut the engine off Gannet Point. Bring a windproof layer; it's cooler on the water than it looks from the café. Tickets start at $45 & include hot drinks.

  • Two-hour harbour loop, every day from April to October
  • Sunset sailing on Fridays and Saturdays
  • Private charters for up to twelve
"Best two hours of our whole trip." — a guest from Leeds, last summer

Family-run on the harbour since 2011

Our Story

Aldenaire Boat Tours started in 2011 with one restored wooden launch and a captain who couldn't stop talking about the harbour. Today we run four boats out of the old fish market pier, and every skipper still lives within sight of the water. We keep groups small so you can hear the guide, ask questions, and lean over the rail when the dolphins show up.

What hasn't changed is how we run a trip: we check the forecast twice, we never sail past the point in a swell, and we'd rather refund you than take you out on a day that isn't worth it. Bring a jacket — it's always cooler on the water than on the pier.

Large Group Hopping Sandbars in Key West

If your group is larger than 6 and you have a hard time finding a boat ride to the sandbars because of the 6 passenger limit, we are here to help.
