CB1 :

That looks great. Will you fish from it when the pond is iced over but before you put up the other unit ? If so don't try to walk past it to the pier end and slip off the side . Ice or not it would still be verrrry cold.

A couple of 1 x 2 fir strips screwed accross the bottom where you have the existing screws would hold it down better without polking more holes in the bottom and with less chance of tearing loose.
