What is your opinion about positioning fishfinder/GPS near a compass or
a VHF radio?

The VHF radio will have a magnet in the speaker and should be kept
well away from the compass if possible. The fish finder is probably
less critical but you should test it before mounting by placing it
near the compass and watching to see if the compass heading changes.

Thanks for explaining the reason why I need to keep the radio away from
the compass. You are right; the magnet inside the speaker of the radio
will likely cause problem to the compass. On the other hand, the
fishfinder and the GPS device should not have any magnet inside.
Therefore, I have a feeling that I should be able to mount them near
the compass. Great! Now, I don't need to worry about how to mount
those devices in my boat.

One thing new that I read from Shakespeare-marine web site is that I
must keep the VHF radio at least 3-ft away from the VHF antenna.
Because I will mount the VHF radio right underneat the T-top and I will
mount the VHF antenna also onto the T-top, I will have to mount them
each in either side of the T-top. This means I need to keep the
following rules in mind when I position all the devices in my boat:
- Keep a VHF radio at least 3-ft away from a compass.
- Keep the VHF radio at least 3-ft away from a VHF antenna.
- Keep the VHF antenna at least 3-ft away from a GPS antenna.
- Test all the devices before mounting them permanently.

OK, this is easy enough.
