I was thinking about this whilst eating my din dins.
I want to be able to remove the box when the boat is ashore yet keep it from sliding about all over the place or bouncing about.
The box i have got is a pretty tight fit between the tubes at the bow infront of the console. There is a lip that rises above the deck about 4 inches. my plan at the moment is to get some of that honeycomb matting Nasher was talking about in a thread on here a few months ago and cover the floor in the section infront of the console.
Then drill two holes through the lip and run two loops of bungie cord over the box (one either side) and back fixed through the hole. I figured the weight in the box would hold it down reasonably well. The bungie could be tight enough to have a good grip and stop a lot of the movement but easy enough to slip over the sides and get access to the box.
have attached a truly rubbish to try and show what im talking about.
Clearly if you dont have a well placed lip in the deck this will be no use! Sorry.
