With the 'big' engines fitted the AF could easily maintain 36 knots without going to 120% power. The best speed I ever witnessed on the AF was 43 knots 'over the ground' with a following tide in the Pentland Firth - chocks away, or what?
Those speeds absolutely boggle the mind !!! Given that that was in the 70's, what speeds are such ships capable of now.
My memories of crossing the pacific at 12 knots, with a couple of stops to change fuel valves must sound quite archaic ; yet that was early 60's.
With all those advancements down below, what happened on the bridge/ Presumably sextants are quite obsolete!!
