This is another of those endless debates, like whether to carry a sextant or use paper charts (I have both, so having declared myself you know where this is going
). I like the knotmeter for checking engine performance. I also like to know current for navigation, which means knowing speed through the water as well as speed over the ground. But without a knotmeter, for navigation purposes I guess one can always "see" current by watching the GPS breadcrumb track trend, and for engine monitoring purposes, one can always check speed/rpm curve on a calm day at slack water.
Like MarkS, I added an engine hours clock too.
