I installed Touche's knotmeter nearly on centerline forward of the keel to be a) in less turbulent water and b) to avoid the port/starboard tack bias. It is under the step in the V-berth. An inspection port allows access.
If I recall, in this case, the original poster was using GPS speed so knotmeter location was not a factor. Dennis C.
