When I am shooting at them

I usually figure about 5 knots. That way I can calculate the lead and hit them with the first broadside. Other than that what are you asking?

Hull speed

Theoritical hull speed for displacement hull ( keels)is 1.34 multiplied by the square root of the waterline length. A 25 ft mirage probably has 22 ft or so of water line. the calc will give you a max speed of 6.2 knots
