On my boat in particular, yes, we can point OK in about 5 knots true with the board up. We can come up a little closer with the board down, or partially down, but we can lose up to half a knot of boat speed. Itís more advantageous for us to leave the board up, fall off the extra 2 or 3 degrees and make it up with speed, especially on the 1 or 2 mile legs that we run.
For us, that crossover point between drag vs. lift was right around 10 knots apparent.
Thereís nothing that says my CB is in the best condition though, probably could use some work. Went down for a look a couple of weeks back and found no damage, everything felt smooth enough, but that means nothing. I wear glasses and underwater, even with a mask in clear water, things are still a bit fuzzy.
Iíd like to get that board out of there when we come out this fall. Give it all the attention it needs.
