This International Moth was undergoing pre flight checks down on the slipway, judging by those foils and the fuselage hull.
Despite the delicate appendages and the sheer size of the hull and outriggers launching seemed to be a fuss free procedure.
It wasn’t an especially windy day perhaps 8-12 knots near perfect conditions so after a couple of short tacks the Moth was up of its foils and hurting down river. The picture doesn’t show it very clearly, the hull was some 9 inches to a foot out of the water supported on those tiny hydrofoils and the uplift generated as they travel through the water.
