My friend has a 60x4 dock at his house. Water is only about 5' at the end. We wanted dock whips for our 25 & 26 ft bowriders, due to the wave action at the dock.

We had 90 degree brackets with gussets made out of aluminum, with one side of the 90 drilled with 4 holes, and the other 90 drilled to match the whip bases.

We drilled through the dock frame and secured the brackets with bolts, nuts, and lock washers. We then drilled up through the brackets for the three mounting bolts for the whip bases.

Result: : our boats ride the wakes and waves, and the dock is rock solid. There is no stress on the decking. This was recommended by the dock manufacturer.

One other thing we did was mark the 6 10' sections. #1 has hinge on one end and connects to #2. The other end of 2 we marked 2->3. #3 marked 2->3 & 3->4, etc. Eliminates problem of slight changes in drilling from one end of a section to other.
