Main Belt inclined 15 dg 200mm=270 mm

With inclanation on such a short (low?) belt hadrly any of the waterline will be protect, with high risk of either submerging the belt att full load, or exposing it out of water if going light.

Main Belt inclined 15 dg 200mm=270 mm

Belt heighten 1 m

[P3D]

15* inclination reduce belt height by , and further reduce effective belt height (compared to what the same height would be able to protect on a straight hull) to long-distance shooting. Height reduction from the first effect is 11cm. From the second effect, at 15* angle of fall, the effective height reduction is a further 22cm - assuming the original 3.31m height.

[ledeper]

you mean heighten the belt by 11cm+22cm?From 3,31m to 3,65m?(I am a math illiterate) ;D ;D
