Description

(1) Further embodiments and advantages of the invention are explained in more detail below with reference to the drawings and the description.

(2) In the drawings:

(3) FIG. 1 is a schematic representation of the eight in side view and in plan view,

(4) FIG. 2 is a representation of the boat plan of the eight showing the individual segment sections as well as the width ratios along the waterline,

(5) FIG. 3 is a representation of the bow profile and the stern profile and

(6) FIG. 4 is a representation of the lead angles of the stern and bow.

(7) FIG. 1 shows the basic structure of the men's and women's eight according to the invention, specifically the arrangement of the sliding seats 1 and the foot stretchers 2 as well as the bow 3 and the stern 4. This figure shows the particularly narrow design, i.e., in particular the very small ratio of total width to total length.

(8) The shape of the ribs can be seen in FIG. 2. The length of the waterline WL for the men's eight at a total weight of 938 kg is 17,211 mm±5%, preferably ±3%, most preferably ±2%. The total length of the men's eight according to the invention is 17,320 mm. The length of the waterline WL in the women's eight according to the invention at a total weight of 858 kg is 16,793 mm±5%, preferably ±3%, most preferably ±2%. The total length of the women's eight according to the invention is 16,890 mm.

(9) The views of the bow 3 and the stern 4 can be seen in FIG. 3.

(10) FIG. 4 is a representation shortened in the longitudinal direction with a scale of 1:10 in which the lead angle α of the bow 3 and the lead angle β of the stern 4 are illustrated on an enlarged scale. The angles for the men's eight are α=4.8°±5%, preferably ±3%, most preferably ±1% and β=5.9°±5%, preferably ±3%, most preferably ±1%. The corresponding angles for the women's eight are α=4.8°±5%, preferably ±3%, most preferably ±1% and β=5.4°±5%, preferably ±3%, most preferably ±1%.

(11) Given the division into 15 segment sections/ribs having the same spacing, which can be seen in FIG. 4, the values already given above for the respective cross-sectional area below the waterline WL, the respective circumference below the waterline WL, the respective width at the waterline WL and the respective width ratio based on the middle segment 7 are obtained for the men's eight and women's eight.
