[Sentoa] Fuel Balance

[MayorTC at aol.com]

I agree with Steve. Our NT 37 lists to starboard even after adding  
additional weight to the port side. We have the Onan generator on the port side  and no 
crane or ding on the starboard, but it still lists to starboard. The foot  
squiggie takes care of the shower drain problem. Like Steve, we have experienced 
 any performance problems.

Our  NT37, like most, has a slight stbd list.  I have a few sandbags in the  
port lazarette aft which help, but more are needed.  My back is too  sensitive 
for me to put more in there, but maybe at the next haulout  I'll have the 
yard do the grunt work.  


The question I'm posing now is:  why bother? Why take special  measures to 
correct it? It's just inherent to the boat equipment installation.  My theory is 
that it has to do with the galley and head, and associated gear  and 
furniture, being on the stbd side. I doubt if an inverter, by itself (but  maybe in 
connection with everything else)  would be the culprit.  Eyeballing it with a 
sharp eye,  it can't be more than 2 or 3 degrees in  my case.  You'd have to 
have a special set of devices to actually measure  it, because you cannot 
realistically install a typical inclinometer, which  only gives you crude 
indications, at absolute dead level.  


Obviously, on the 37s, the dink sits on the stbd side on the boat deck.  
However, the 37s have a stbd list with nothing up there. Of course the  dink and 
an electric hoist (we don't have one, but wish we did) would  definitely add to 
a stbd list.  


Maybe the factory has corrected it in the newer models.  I  keep the backup 
beer supply under the port settee, so that helps, right?  Yes, I know there is 
some theoretical, but arguably minor, issue with  handling and fuel 
consumption if a hull is out of trim, but I'd like to see  anyone produce data on in the 
case of the NT37s.  


I don't think it affects the way the boat handles or rides to any  noticeable 
degree (we've owned four large boats). I believe topside weight, on  any 
boat, is a bigger factor in roll stability than just about anything  else. 


Visually,  admiring lookee-loos (and there are plenty of  them....isn't that 
great?)  on the docks never notice it unless you point  it out to them, and I 
don't.  The only functional consequence seems to be  that the shower pan 
doesn't drain as well as it should, so we live with that.  I don't worry if one 
fuel tank is somewhat lower than the other.  The relationship between them 
remains fairly constant and I keep the  crossovers open at all times, except when 
re-fueling.  In my fevered  brain, the fewer fuel connections to worry about on 
a boat, the better.  That said,  JOLIE BLOND's solution is an elegant one for 
sure;  it's just not for me.

We  own a 2004 37'. The main engine fuel line is connected to the port tank. 
There  is a crossover from the port to the starboard tank. However, when 
running for  a period of time, the port tank runs down much faster than the 
starboard. Even  after leaving the boat sit overnight, there is still a large 
difference  between the levels in the tanks. Is there anyway to run the main engine 
off  the starboard tank exclusively? Or at least ensure that the levels remain  
balanced?
