- ✓ One-half maximum ahead service speed or 7 knots, whichever is greaterCorrect
- C. One-half maximum ahead service speed or 5 knots, whichever is greater
- D. Maximum astern speed
Why B is correct
46 CFR §58.25-10(d)(2) requires the auxiliary steering gear to move the rudder from 15° on either side to 15° on the other in not more than 60 seconds at deepest loadline draft running at one-half maximum ahead service speed or 7 knots, whichever is greater. Maximum ahead service speed and maximum astern speed are not the applicable conditions for the auxiliary gear test.
