FYI, we don't even bother putting ours in any more. It gets fouled very quickly, and we have boat speed (over the ground, anyway) via gps.
If you are using an integrated system, you may want to leave it in. The knotmeter, in conjunction with the GPS, can make set and and drift estimates. It can also be used with the wind instruments to make calculations for true wind angles and true wind speeds.
