Boat was splashed yesterday after being hauled for Irene. Had the yard powerwash the bottom, which had a lot of soft growth after being in the water for a year and a half (though no barnacles and prop zinc was >90%, prop was virtually clean using PropSpeed). Wow, what a difference! 1.5 - 2 knot speed increase in less than 10 knots apparent wind. What a difference a clean bottom makes. Beautiful day on the lower Bay today.
