Like I wrote above, our "planning speed" is a paltry 6 knots. That keeps the pressure off, and lets us sail quite a bit in the 4-7 knot boat speed range even if the apparent wind is in the 5-10 knot range. So if lucky with 15+ knots apparent, we can sail at 9-14 knots boat speed (I start to throw in reefs beyond about 22k apparent, or slow it down further for comfort if there's a steep chop) or if we get less than 5k apparent we'll likely motor at 8 knots.... but I'm not a fan of running the engine hours-on-end and I'd just as soon vary the destination by distance or direction so we don't need to.
So bottom line, it' extremely variable. The vacation is where WE are, and it's not when we get "there", it's in every moment. I try to remember that, though we do occasionally succumb to "delivery mode" or trying to beat weather or darkness, or some other commitment. Unfortunately sailboats and schedules don't mix.
The admiral likes to go ashore at the end of the day and after about 10 or 12 hours she's done sailing, if she has a say (and she does ). Harbor-hopping with 4-8 hours of sailing a day is generally just about right for us.
We plan on 50-70nm days when destination-oriented (stopping in the late afternoon) and might decide to push it further if making good speed under the right conditions but I'm happy when the Admiral's happy. When we go to Maine we probably won't go up (or down) in one hop.
