Aviateur 5,70m is a very stiff boat with a big interior volume.


-Galley with one stove
-High stability for the lenght.
-Forward anchor locker.
-Companionway, where you can handle all
-Forward double berth, very wide, with a big deck hatche just above.
-Keel sleeve stopped at the berth level.
-Big volume inside, with big space given by the "empty" bulkheads.
-Side berths 60cm by 2m of lenght.
-Big volume above berths
-2 couple tillers: 1 outside and one inside, to helm under the plexiglass bubbles.
-Chart table


Very simple developpable construction - Hull with only 4 chines, with a flat bottom hullshell. Deck with 2 chines, with flat panels. Construction: epoxy-marine plywood.

If you choose to built Aviateur 5.70m at home, the price of the materials (near european prices) is about 10100 € without sails. Mainsail+solent+spinnaker = 3470 € Time of construction: about 400-500 hours.


She is trailerable too. (boat,625kg + trailer,180kg = 805kg to be trailered). When the boat is driven in the water, the trailer is immersed (like the open boat of the same length): a rope is placed betwen the ball of the car and the trailer. in the diagram below, you can observe that the fixed rudder-skegs don't touch the bottom.


The boat can be rigged alone: a transverse axis enables the mast to rotate around with security. We place the shrouds on their chainplates, and rotate the mast forward with a halyard. Then, we just have to place the stay.
