It means that. Further, “in the rear end position Xe” means “in the plane of the fin that includes this rear end position Xe and is perpendicular to the line segment connecting the front end 6f of the root portion of the fins 6A to 6E and the rear end 6a of the root portion. ".
- FIGS. 9 and 10 has an outermost portion that protrudes slightly before the front end 6f of the root portion, and a position Xe of the rearmost end is behind the rear end 6a of the root portion. It has characteristics.
- FIG. 9 is a schematic view of the fins 6C as viewed from the side of the hull, and FIG. 10 shows a schematic lateral projection when the propeller boss cap 5A and the fins 6C are rotated around the propeller rotation axis.
