[QUOTE=RolfP;1512209]Zero
leaks in four summers but I'm adding a
knot meter (thru hull) this spring so that's the reason to also add the bilge pump. This is my
small boat I am testing my skills on instead of sinking my big boat. :-)
Keep it simple, use your
GPS for speed over ground. Knot meters are a pain, add a hole in the
hull, foul quickly, and only tell you how fast the
water is travelling past your
hull. If you've got a strong
current and try to judge distance and time to get there SOG is more useful. If you're
racing and trying to tweak a bit more speed out of your
sails you may find a knot meter useful. I'm plugging that hole in the hull on my boat, YMMV.
