Last night I installed two new flush fit rod holders on Jersey Girl, one in each corner of the splashwell top.
Certainly focuses the mind when you're about to cut a great big hole in your boat...!
Firstly, measure, measure then measure again. See my marking out below and how I adjusted the position of the holder before cutting!
Here's the first cut, in the starboard corner.
And on the port corner, the drill bit snapped! Bugger!
But I could keep the cut going and it finished fine.
