would you have felt better if the boat came with pre drilled holes for mounting riggers....get over it ...and drill the holes..you can always leave the base plates on the boat at resale...or selll the riggers with it
just curious as to how your going to deal with adding a tranducer thats below the waterline...
dont forget to silicone every bolt you put through the hull under the waterline...
Congrates on the new ride and good luck in your rigging..
Cheers
