Congrats on your 420, that is one fantastic yacht. As Google tells us, you can calculate your hull speed as such:
How to calculate hull speed?
As a very general rule the maximum speed of any displacement hull--commonly called its hull speed--is governed by a simple formula: hull speed in knots equals 1.34 times the square root of the waterline length in feet (HS = 1.34 x ?LWL).
The waterline is sq. root of 37.333 feet = 6.11 x 1.34 = 8.18 is the IP 420 Hull Speed.
Now, on your trip to Key West, please take some photos and show us these speeds. We are counting on that

Thank you for the info, I will check it out. I also have looked at Fiverr for the same work. Your logo is great, well worth the money.

30 knots? The sailboat is not a transportation, it is a style of living. If you average 5 to 6 knots on a fair day you should feel content. As a friend of mine used to say - "A motorboat owner gets to wherever he wants fast. A sailboat owner is already there..." Enjoy...

Agreed in general. However, we are planning our 1st overnight sail of 180 nautical miles to an unfamiliar harbor with a somewhat hazardous approach. One knot can make the difference in arriving in the light or dark. Hence, the question about speeds in different conditions. I now the speeds of a Beneteau in all those conditions but not my new lady.
