The fisherman's staysail, a four-sided fore-and-aft sail, is not strictly a staysail, but is clewed abaft the foremast.
One of these lights or shapes shall be exhibited near the foremast head and one at each end of the fore yard.
The ship is 106ft m long by 25ft m wide, 236 tons displacement, 4 masts (mainmast, foremast, mizzen, sprit), and 6 sails.
Staysails may be carried between any other mast and the one in front of it or from the foremast to the bowsprit.
Both its main mast and foremast were replaced.
Both the ketch and the yawl differ from the two-masted schooner, whose aft mainmast is taller than the foremast.
There are 3 jibs and 4 square sails on the foremast.
The mainmast was lateen-rigged with a trapezoidal mainsail, but the foremast carried the conventional square course and square topsail.
