Abstract
Abstract The method of converting sails called Roller Wings, which are mounted on a wire and attached attached to a furling gear and used when the only wind available is dead astern, into different sailing configurations suitable for other types of winds, by moving the furling gear to a preselected point, altering the alignment of the wings to meet the desired configuration and unfurling the wings in such a way as to achieve the new configuration.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
74 words
The method of converting Roller Wings into a different sail configuration which comprises: a. moving the furling roller to a preselected point on the deck of a vessel; b. aligning the respective clews of the furled wings and connecting the sheet associated with each wing to both wings so that the clews are held together by the sheets; c. releasing the roller such that both wings unfurl with their respective clews remaining substantially aligned.
Claim 2
Independent Claim
74 words
The method of converting Roller Wings into a different sail configuration which comprises: a. moving the furling roller to a preselected point on the deck of a vessel; b. aligning the respective clews of the furled wings and connecting the sheet associated with each wing to both wings so that the clews are held together by the sheets; c. releasing the roller such that both wings unfurl with their respective clews remaining substantially aligned.
Claim 3
Dependent Claim
27 words
The method of claim 1 where the furling roller is placed at a point substantially at the bow of the vessel and the wings are completely unfurled.
