TRAVEL TIME IN BLACK SAILS

BLUE : direct route Charles Town - Nassau

RED : route taken by Flint after having been blown east by the winds

On the way back from Charles Town (XVIII.), Flint explains to Silver that they are south of Inagua - having made a stop at Tortuga -, still on their way to Nassau because the "winds blew us east. "

THE WALRUS’S SPEED

the Walrus top speed is 7.5 knots. That speed was reached while chasing the Andromache (V.) by risking the masts’s integrity (argument between FLINT and DE GROOT, the t'gallants should not have been unfolded in that wind). With a proper carrening, that speed could be reached safely (“A clean hull means an extra knot or two in speed” in IV.), but the carreening was not completed (in IV: “A few more days, we’ll have the keel cleared and tarred and she’ll be ready to go back into the water”, but the very next day they were chasing the Andromache, as established by SILVER mentionning Randall’s amputation being the previous day).

the Walrus chasing speed is 6 knots, in favorable winds (the speed reched before risking the masts’s integrity, see above).

the Walrus average cruising speed is 5 knots (my estimate, somewhat arbitrary : I take into account the occasional slow wind and a lighter workload on deck to allow shifts for the men to rest).

Average travel time, at 5 knots :

1 knot = 1 nautical mile / h

5 knots = 5 nautical miles / h = 120 nautical miles / 24h

Nassau - Port Royal : 754 nautical miles 754 / 120 = 6,2 ; 6 days at 5 knots

Nassau - Tortuga : 539 nautical miles 539 / 120 = 4,5 ; 4,5 days at 5 knots

Nassau - Havana : 407 nautical miles 407 / 120 = 3,4 ; 3,4 days at 5 knots

Nassau - St Augustine : 511 nautical miles 511 / 120 = 4,2 ; 4 days at 5 knots

Nassau - Charles Town : 631 nautical miles 631 / 120 = 5,2 ; 5 days at 5 knots

Nassau - Savannah : 623 nautical miles 623 / 120 = 5,2 ; 5 days at 5 knots

Nassau - Boston : 1426 nautical miles 1426 / 120 = 11,8 ; 12 days at 5 knots

*The farther away, the most likely it is to wait days for the wind, or be blown off course (see map above).
