BOAT-COMPARATOR Guide
No-licence boating in the Gulf of Morbihan: spots
Where to go without a licence in the Gulf of Morbihan: Ile-aux-Moines, Ile-d'Arz, easy anchorages and the tidal-current trap at the narrows.
The Gulf of Morbihan is one of the few French waters where a no-licence boat truly makes sense: a small inland sea dotted with islands, short hops well suited to a 6 hp engine, and scenery that changes at every headland. With Boat-Comparator you compare the area's rentals side by side, affiliated with no platform; this guide mostly tells you where to go — and where the water turns genuinely tricky.
What a 6 hp engine really allows
In France a no-licence boat is capped at a 6 hp (4.5 kW) engine, for daytime use within a zone set by the operator. At roughly 5 knots, plan on a realistic radius of 2 to 5 nautical miles around your base — usually Vannes, Arradon or Larmor-Baden. That is plenty to reach Ile-aux-Moines, Ile-d'Arz and a handful of sheltered anchorages, without ever aiming for the ocean exit, which is well beyond a small engine's reach.
The spots you can actually reach
Ile-aux-Moines is the safe bet: the Trec'h point and Guric beach offer easy anchoring over clean sand. Across the water, Ile-d'Arz and the Berno inlet suit a quiet lunch stop, sheltered from the chop. To the east, the Sene slipways and oyster beds are worth a slow cruise, binoculars ready for the reserve's birdlife. Avoid the western part, towards Gavrinis and the Port-Navalo narrows, where the current is a job for the regulars and rarely for a first-timer. A pair of binoculars and a picnic turn the gentle hop to Ile-d'Arz into an easy half-day, with plenty of quiet water in between to potter about.
The current trap
The gulf empties and fills through a tight neck, and the current there can far exceed a 6 hp boat's speed: against it, you would barely move, or even go backwards. The rule is simple — plan your legs around slack water, run with the tide where you can, and give up on crossing the narrows. Note the tide times before you cast off. Most operators cap the permitted zone well upstream of Port-Navalo anyway, a limit you will see on no-licence rentals in Vannes.
Practical tip and booking
Set off early: the water is calmer before the afternoon sea breeze, and the rising tide opens up the eastern shallows. Carry a chart of the gulf, as the oyster beds and shoals surface quickly at low water and catch out the inattentive. To find the right boat at the right price — typically 100 to 250 EUR a day for no-licence, with a 10 to 25 percent spread for the same boat between platforms — compare through Boat-Comparator, which gathers Boataround, SamBoat, Click&Boat and GlobeSailor.
