Flat Floor, Gas Tank, Line Storage Rack

FLAT FLOOR - The false floor in Panache's port locker is constructed of 3/4" plywood with vertical supports (1x8)" of solid spruce planks shaped to fit the hull form along with a UHMW foot at the corner.  It requires a bit of "art work" to draw the floor line along the curved hull side of the locker.  To make this job easier, draw a fore/aft line at the height of the false floor, parallel to the cockpit sole.  Continue the line from the corner out to the hull along the bulkhead side of the locker.  Finally join the ends by drawing the line along the hull using a projected laser line.  

To make it easier to draw the line, position the laser on a temporary flat surface in the corner of the locker with the edges parallel to the lines drawn.  Project the laser line to the ends of lines previously drawn.  Draw your line on the hull along the laser line.  Don't have a laser?  Fill the locker with water to the desired depth and draw your lines just above the surface!  Probably a lot easier and you get a chance to check the water tightness of the locker, plus clean it!  Finally, use cardboard to make a pattern so you don't waste your last piece of plywood.   If you want this assembly to last forever, saturate the wood in epoxy and use some UHMW for the foot (at the corner) so the wood stays high and dry.  Water will eventually accumulate to this low spot from various leaks.  If there is water in the "sugar scoop" aft of the cockpit, it came from the gudgeons, transom chain plate or cockpit drain fittings.  If the "sugar scoop" is dry the water came from the scupper, locker lid hinges, gunwale fittings or condensation. 

To clean the bottom of the locker or remove the water, just slide the shelf aft to expose the bottom.  Then you can use a large sponge (if you have long arms to reach the bottom) or a pump to empty it.  This spot should be the first place to install an electric bilge pump on an SJ23.  See Tech Tip C12.

GAS TANK - One of the biggest advantages of a flat floor is to keep the gas tank high and dry plus level, so you can burn ALL the fuel for maximum operating range.  Now you no longer get those odd comments from the dock watchers as you hold the tank level inside the locker while you tickle the tiller with your toes to motor that last little bit to the gas dock!  Just think, you can actually have an accurate reading on the fuel gauge.  What a novel thought!  Drill a couple of 2" holes through the shelf, under the tank, to keep the bottom of the tank ventilated (dry).  It helps to prevents rust.  To prevent the gas tank from sliding screw four fiddles (strips of wood from an old hockey stick) around the base of the tank.  Hockey stick handles are a renewable resource of excellent hardwood in Canada!  If you sail heeled over more than 300 strap the tank to the shelf to keep it inside the fiddles.  Although in practice, I've found that the low profile 2.5 gal Merc tank does not move.  It's still a good idea to strap it down.   A taller 5 gallon tank might tip so strap it down.  For convenience, I drilled a hole in the false floor to hold a vinyl bottle of 2 cycle oil and installed a stub of wood on top of the shelf to support an inverted funnel.  The gas tank shown is a Mercury 2.5 US gallon tank. The floor is big enough to support a 5 Imp gallon tank. 

 

LINE STORAGE RACK - Line is only useful if you can get at it and if it is ready to use.  You always need it for docking, to replace a sheet or to dry your "unmentionables" in the wind.  Line dumped in the bottom of a locker will always soak up water and snarl up so it is miserable to use.  I hate line that stinks!  Line coiled on a rack is easy to find, ready to use and dry.  I built the storage rack shown above to bolt against the forward end of the port locker.  The rack is made of 6" long 3/4" dowels drilled and glued into a (3x4)" plank.  It is very convenient to use, requiring only one hand, and a wet line dries nicely without smelling up the cabin.  A coiled line has never dropped from a peg.
