Lonnie, now I am confused. Is the Turn indicator wrong, i.e., there is no cost for turning less than 36°, other than 1kt per 1cm? So at 36° you pay 2kts? Or do you pay 4kts, since you now pay cumulatively for the 18° and 36° tick marks? Or do you pay 2kts at >30°, then another 2kts at 36°?GregoryI think we're all saying pretty much the same thing. There is no additional cost for turns under 30° (36° to be precise on the Ship Turn Indicator). Just the normal one kt per 100 yds (1 cm in the most popular scale) which is easily measured with a tape measure or movement aid. When a ship executes a larger change of course (> 30°) she incurs the cumulative cost of two kts per tick on the Ship Turn Indicator.

billowen wroteI fear my earlier response reflects some jet lag which I need to clarify. Each 18° tick mark on the Ship Turn Indicator is equivalent to a cost of 2 Kts as described in Section 1.2.3 on page 1-2. Thus, the first tick costs 2 Kts, the second (36°) costs 4 Kts, etc. As a ship leans into a continued turn, lateral resistance increases, costing more "Kts" worth of movement energy. The more she turns, the greater the "cost" of this resistance. In the interest of simplicity, this is reflected as a constant 2 Kts/18° on the Ship Turn Indicator. By allowing minor turns of < 30° to be made without measuring with the Ship Turn Indicator, movement is made easier and captains can, in effect, execute these minor changes in course without extra cost at the normal one Kt/1oo yds due to minor lateral resistance as noted in my earlier reply. For turns > 30°, the cumulative cost is simulated at a cost of 2 Kts/tick. Thus, a two tick turn (36°) costs 4 Kts, etc.
I think Bill's speed cost breakdown is correct.GregorySo to make sure I've got it:Cost in Knots / For Turns (degrees)[ul]0 / 1-172 / 18-354 / 36-536 / 54-718 / 72-8910 / 90-107etc. up to 20 / 180[/ul]
