I suspect part of your problem is you don't have a representative ground pl=
ane because the boat is on land. Once the boat is in the water get half an =
hour to do the dip test again and see if it changes.

You may need to put some 'ground radials' at the antenna to give it a 'prop=
er' ground plane to work against, as it is up on the 'roll cage' to get som=
e height. This will also modify the way things react when you move the coax=
 around, and should make it a lot less sensitive to changing its position.
