A buddy of mine did Chattanooga to Charleston in a 25' single
Like you say, maintenance
is especially critical for long runs with gas engines. An engine
in a boat runs like it would in a car if you had a trailer behind it and was climbing a never ending hill.
You are probably familiar with charts
, dams/locks, etc., so I'll skip to something you may need to think about
Sometimes it can be a long way between fuel
stops. It's important that you really
know your fuel consumption
. By really
, I mean you should know how much it burns at varying RPM
ranges. How does large waves affect it (can be a lot), how about a stiff head wind
(almost none, usually)? How much does that new genset burn?
If yours is like the one I found on the web, it has 150 gal of fuel. That's probably cutting it close. I'm gonna guess that gets you about a 100 mile range. That is, 150 range with a 50 mile buffer.
What that means for you is you need to stop for fuel every day. If you are planning on staying in marinas
every night, this is no big deal, but even then it's a pain to sometimes be ready to go, but the fuel dock
isn't open, yet. If you plan to anchor
, then those daily fuel stops cost you an hour or better each. Also, with that limited range, it means that before you head
out in the morning, you should call ahead to the next place you are planning to stop to make sure they are open, got fuel, got enough water
for the time of day you are going to be there. (I only drew 30", but one place didn't have even that during low tide!)
It can certainly be done though!
I did 1000 miles on the ICW
in a 36' 22,000 lb wood boat with 250 gal of fuel and a 100 mile usable range. It just made the trip a little longer and took calling ahead and planning carefully. I had a fuel stop charted for every 50 miles, and red marks for places that they were further apart.
But when I did another 1000 mile trip in a boat with a 400 mile range, man, it was so much more relaxing.
