Let's see. There is no place on Winnipesaukee that takes more than an hour to get to at 22 kts. If I add fuel burn monitors ($500 x2?) a new MFD ($4000?) I spend $5000. I can reduce fuel burn from 25 gph to 23 gph(?) and save $12/hour? $12 sounds pretty good, but it will take 400+ hours to break even. If I'm cruising at displacement speeds (where I have never dumped a tray of hors d'oeuvres), my fuel burn is more like 5-8 gph.
Points:
1. Saving on fuel can be expensive
2. Fuel is only a small part of boating costs
3. You don't have to go fast to enjoy boating.
