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.
