I really do like your idea for the logbook. Good thinking, I'm definitely going to steal that idea.
We have two GPS on board, one installed at the chart table with a cockpit repeater and a handheld. I'll probably make that two handheld shortly.
As an aside, our log fried itself some time back. Now we use the handheld GPS instead.
Rains stopped for awhile in old Sydney Town, need to head off down to the old girl to check for leaks.
Cheers for now
