If your like me and most you could probably just pack the 2 flashers and 2 favorite lures you will use and leave the rest at home.
My boat is 17ft. I keep tackle sorted in the plastic containers sorted by hootchies, spoons, anchovie heads, terminal tackle, jigs, halibut... and just take the couple of cases that I will need that day and try to only have 4 flashers with me. A good storage area for these containers on board would be cool.
I will be interested to see what ideas people reply with.
