One of these....and it pays to have it.
WOW... saw this $15 dollar range gagit at West Marine called a Inclinometer... and being on a long range trip of about 300-400 miles solo on my old classic 18 Angler, I thought the boat running flat to the surface would be more comfortable, look better, and get better fuel efficiency. I was kinda blown away at the mileage differance. On a previous similar trip, I "averaged" in similar running/water/weather conditions about 5.5 mpgs on my 18 Angler with the 50 hp suzi, same prop... This mileage was a combination of up/down stream in the Old Hickory Lake portion of the Cumerland River. On a tighter up river run, ( more pronounced current), running true level, I gained just over 1 mpg... I bought the cheap one, and when I clean my truck today and find the receipt, I can give you the model number too..
Has anyone else played with this as to be sure they ARE running level. I also found that what I thought "felt" level, using the trim tabs, was not correct. I found that by 1st leveling the boat sitting still, then just using the tabs for bow level changes produced a nicer ride, free"er" steering... Kinda made me go Hummmmm
Something to be said for a neat little boat that you can just slide your 60 quart cooler(s) from side to side and make such a differance.
