Re: Cape Dory stuffing box leak
As Faster has posted, the lock nut is loose.
It also looks like some glass has been poorly laid up in the bilge, further restricting a tight space.
My personal belief is that you need to make your own wrenches for this purpose. The adjustable spanner that almost everyone recommends (the silver one pictured next to the pipe wrench) is an ungodly awful tool and is totally unsuitable for packing nut adjustment-- just an exercise in frustration. It is not difficult to make your own wrenches out of 1/8" steel plate (available at the big box hardwares). I made mine by modifying a pair of non-adjustable "stamped steel" plumbing wrenches that I got at Home Depot for about $8 each. I cut them to proper shape with an angle grinder then welded handles on them from 1/2" angle iron, attaching them at an angle like all wrenches are made, to allow you to turn the nut from different approaches. Once you make the wrenches, hang them somewhere close to the stuffing box and pass them on to the next owner when you sell the boat.
They don't have to be terribly strong-- once the packing nut is loose and cleaned up, it doesn't take much torque to tighten it properly.
