Gaff rigged schooner in summer haze

Sailboat gaff rigged schooner

This gaff rigged schooner is an enlargement of a long shot thru a telescope. Not very clear but so lovely! Per Wikipedia, for those of you who know something about sailing:

Gaff rig[1] is a sailing rig (configuration of sails, mast and stays) in which the sail is four-cornered, fore-and-aft rigged, controlled at its peak and, usually, its entire head by a spar (pole) called the gaff. Because of the size and shape of the sail, a gaff rig will have running backstays rather than permanent backstays.

The gaff enables a fore and aft sail to be four sided, rather than triangular. A gaff rig typically carries 25 percent more sail than an equivalent bermudian rig for a given hull design.[2]

A sail hoisted from a gaff is called a gaff-rigged (or, less commonly, gaff rigged or gaffrigged) sail.[3]
