Two Nations, One Sea: A Private Day Cruising St. Maarten/Saint Martin

Two Nations, One Sea: A Private Day Cruising St. Maarten/Saint Martin

Snorkel reefs, skim turquoise channels, and watch jets graze the beach—your boat, your pace, your Caribbean.

Simpson Bay, Sint Maarten

boat charters, water activities, wildlife natureMarchwinter

The morning sea wears that Caribbean shade that convinces you it’s lit from within—turquoise smoldering to cobalt at the horizon. You step aboard at Simpson Bay as the trade winds breathe across the lagoon, teasing flags and hair, urging the bow to point seaward. The captain eases the throttle and the hull hums; mangroves slip past like an opening curtain. Out on the open water, the island’s twin identities—Dutch and French—unfurl from the coast like a map made of headlands and hidden coves.

Trail Wisdom

Time the Planes at Maho

Arrive between late morning and mid-afternoon for the busiest jet schedule; ask your captain to anchor at a safe, off-beach angle to avoid jet wash.

Go Reef-Safe

Use mineral-based, reef-safe sunscreen and wear a long-sleeve sun shirt to protect coral at Creole Rock and Tintamarre’s turtle grass beds.

Beat Motion Sickness

If you’re prone to seasickness, take medication 30–60 minutes before departure; the leeward side is usually calmer but conditions can change.

Cash for French-Side Beach Shacks

Some eateries on Pinel or in Grand Case prefer euros or cash; bring a small stash for lunch and chair rentals.

Local Knowledge

Hidden Gems

  • Happy Bay’s quiet crescent beach, usually calmer than nearby hotspots
  • The north-side sandbar at Pinel Island for a quieter swim away from the main beach

Wildlife

Green and hawksbill sea turtles, Brown pelicans diving along reef edges

Conservation Note

This coastline includes marine reserve zones—use mooring buoys instead of anchoring on reef, wear reef-safe sunscreen, and give turtles space while snorkeling.

St. Martin/Sint Maarten has been shared by France and the Netherlands since the 1648 Treaty of Concordia, making it the smallest island divided between two nations.

September–November can be stormy; flexible plans and close attention to forecasts are essential.

winter

Challenges: Breezier days, Slightly cooler water

Photographer's Notes

Bring a polarizing filter to cut surface glare and deepen tropical blues. For plane-spotting at Maho, go wide (16–35mm) and shoot 1/1000s to freeze the approach; time bursts as aircraft pass the threshold. Underwater, use a red filter or set custom white balance at depth. Keep lenses dry with a microfiber cloth and stow gear in a dry bag during spray. Drones are heavily restricted near Princess Juliana Airport—do not fly within the no-fly zone.

What to Bring

Long-Sleeve Sun Shirt (UPF 50+)Essential

Shields against strong UV while reducing sunscreen use that can harm reefs.

Reef-Safe Mineral SunscreenEssential

Protects skin and helps preserve coral health in the marine reserve.

Dry Bag (10–15L)

Keeps phone, wallet, and a spare layer dry during spray-heavy runs between bays.

Motion Sickness Prevention

A non-drowsy tablet or acupressure bands ensure comfort if seas get choppy.

Common Questions

Where do most private charters depart from on St. Maarten?

Many launch from Simpson Bay or nearby marinas on the Dutch side; exact pickup is confirmed after booking.

Do I need a passport to visit the French side by boat?

There are no routine checks when cruising between the Dutch and French sides, but carry a photo ID; your passport is required for international entry to Sint Maarten.

Is snorkeling gear provided?

Most charters include masks, snorkels, and fins; bring your own if you prefer a custom fit.

Can children join this trip?

Yes—private charters are family-friendly. Request child-sized life jackets and plan shorter snorkel stops if needed.

What if the weather turns bad?

Captains monitor marine forecasts and may adjust the route or reschedule for safety; you’ll be notified of changes as early as possible.

Will I get cell service on the water?

Coverage is generally good nearshore, but roaming costs can shift between Dutch and French networks—check your plan before departure.

What to Pack

UPF sun shirt and hat to outsmart the tradewind sun; reef-safe sunscreen to protect skin and coral; light cash and a card for French-side lunches and chair rentals; compact dry bag for phones, snacks, and a spare layer.

Did You Know

St. Martin/Sint Maarten is the smallest island in the world shared by two nations, divided peacefully since the Treaty of Concordia in 1648.

Quick Travel Tips

Book winter and early spring dates well ahead—charters fill quickly; Bring euros or a card with no foreign transaction fees for French-side stops; Ask your captain to plan around sargassum reports in late spring/summer; If flying in same day, schedule the charter after your arrival window to buffer delays.

Local Flavor

Refuel at the lolos in Grand Case for smoky grilled fish and boudin; back on the Dutch side, watch sunset with a cold beer at Karakter on Simpson Bay Beach. Rum fans can tour Topper’s Rhum for tastings, then catch live music along Welfare Road.

Logistics Snapshot

Closest airport: Princess Juliana International (SXM), 10–15 minutes from most marinas. Typical departure: Simpson Bay area. Drive time from Philipsburg: ~20 minutes, traffic permitting. Cell service: good nearshore, but roaming may switch between Dutch and French networks. Permits: None for guests on private charters; bring photo ID and your passport for island entry.
