Mike,
And how long have you been a part of this list? Do you really expect me to  
live my other people's rules? Ain't happening. I'm smarter than the rest of 
the  planet. Is it noon yet? Anywhere?

Rummy,

Your mileage not withstanding, your practice  constitutes an unsafe 
condition.  Please review the USCG site  
http://www.uscgboating.org/regulations/boatbuilder_s_handbook/vent_partg.aspx  with particular attention to the 
following portion:
Portable Fuel  Tanks
Compartments used to store vented portable fuel tanks or  containers are 
required to be equipped with natural ventilation.

Cockpit seat lockers in auxiliary sailboats are often used as fuel tank  
compartments for portable outboard motor fuel tanks. If this fuel tank vents  
into the locker, then natural ventilation of this locker is  required.

Since fuel vapors seek the lowest point of any  compartment, gasoline 
vapors should be considered when designing and  constructing a compartment that 
will contain a fuel tank or container that  vents into a compartment. Any 
openings in or near the bottom of the  compartment could permit explosive 
vapors to flow into the bilge of the boat  where an ignition source might ignite 
the vapors.

The "natural  ventilation" must consist of:

(1) supply opening(s) or duct(s)  from the atmosphere or from a 
ventilated compartment or from a compartment that is ventilated
to the atmosphere;
and

(2) exhaust opening(s) into another ventilated compartment  or exhaust 
duct(s) to the  atmosphere.

Each supply opening must be located on the exterior  surface of the boat:
"Open to the atmosphere" means a compartment that has  at least 15 square 
inches of open area directly exposed to the atmosphere for  each cubic foot 
of net compartment volume.  The underseat space meets  this requirement while 
the laz space has insufficient ventilation and connects  with the cabin 
interior and bilge through wiring channels.  These  ventilation requirements 
also apply to batteries that emit hydrogen gas during  charging (solar or 
otherwise) in confined spaces.
For those who are  interested, the site also provides links to pdfs of the 
Boatbuilder's Handbook  for download.  

A simpler version entitled "Safety Standards for  Backyard Boat Builders" 
which I have found very useful over the years is  available  at:

http://files.dnr.state.mn.us/education_safety/safety/boatwater/backyardboatb
uilders.pdf

Please  err on the side of safety.  Don't play around with lives.  Many of  
these rules were established after an avoidable accident.
