I consider things like main engine, trolling motors, depth finders etc. standard equipment but accessories I’ve added that pay dividends are the two nets I installed on my WX1850. One covers the port side opening. That keeps my towel, pliers, a small terminal tackle box and other items from bouncing off the shelf going down the river or road. The second net I mounted under the port console to stuff with jackets, raingear etc. In past times I’ve lost a couple of jackets etc. that I forgot to take out of the boat before hitting the road. Now they make it home safely in the net. Net one I bought from Cabelas. Net two is a cargo net that came with a Tahoe. I folded it in two and used wire ties to close the two sides to make a bag out of it then hung the top from a rod tube I had installed previously. Boat is in storage or I’d add photo.
