Your arithmetic is nearly correct (19.2777 should be rounded to 19.3), but your basic assumptions are suspect.
I’d calculate an 8 knot
sailbboat to AVERAGE less than 8 kts over a full day (day after day) - certainly not more than hull speed
Since you’ll only have about 11 average daylight hours in October*, at those latitudes, I’d assume shorter travel days (than 14 hours), in unfamiliar encumbered waterways.
Assuming a trip covering 2,500 miles, at 7 knots (optimistic), over 10.5 hour days, I’d expect the trip to take not less than
2500 ÷ (7 x 10.5) = 33.33 or 34 travel days
If you could do the trip in May or June, 13 - 14 hour days might be realistic; but would still require 25 - 26 travel days.
