Bill,
Sorry, but no. I don't have any fancy electronics onboard. I use the old  
fashioned method of finding the depth: If the centerboard is dragging, I'm in  
shallow water. The only electronics I have are a VHF radio and a really loud  
stereo system with sub-woofer.

Thanks  Rummy that does make it a lot clearer. Is yours still on some  PVC  
hanging off the back of your boat ?

People,
Not  only are we way over thinking this, but you are forgetting some very   
basic details. First, a GPS receives signals from space, usually a minimum  
of at  
least four satellites at the same time. It has to have a clear  view of the 
sky,  not impeded by the pop top or other obstacles.
A  fish finder will also work as a depth sounder. Mounting the puck  requires 
 
a place where there is little disturbed water for  clarity.....meaning an  
accurate reading for depth, contour and fish.  Some also give you water  
temperature. Placing the puck in the  lazzerette is handy, but you will get  
disturbed 
water. The further  forward you mount it, either thru hull or epoxying  it to 
the 
glass,  the better the readings will be. That being said, you must be  
careful  
not to place it where the glass is to thick or you will get false   readings. 
Attached is a drawing showing an easy method to mount the puck  without  
glassing it in.
Lap top computer circuitry does not like  salt or humid air. It especially  
does not like a dunking. My  personal experience with computers on boats has 
not  
been  good.
