in my collection of boats, I also own a fishing boat.
To properly fish, you need a fishing boat. Period !!
Fishing boats come in every size and shape, with single
or multiple engines.
Bring a big checkbook.
Add to this, various and sundry fishing rods...I have 17....a lot you might think..but not so......fishing is like golf....you need a different rod setup to catch different fish. I will usually always have 4 rods out, with another 4 in " reserve"....when fishing is hot, you simply replace the entire rod, while you deal with the caught fish.
Your fishing line can be 10 lb test to 100 test or more...braided line, fluoro line, etc, etc, etc..you can spend a fortune on lines and lures.
You can spend a fortune on a good rod and reel. Sure, you can buy something at Walmart for $40....but you get what you pay for. Expect to pay several hundred dollars for a single
You can " bottom fish" and also " troll"....both fast and slow trolling depending on your targeted fish..these all require different baits and different rod setups...and the knowledge to rig properly.
You can buy frozen baits, but to really catch fish requires "fresh" bait fish, so you need to become proficient with a cast net and then you need a bait well to keep the bait fish swimming. Chasing after bait fish is an art. That would be very tough to do with a trawler. Bait casting is usually done from the bow. Yes, you can get portable bait wells to lash to your aft deck.
Then comes a proper fishfinder/chart plotter combo, you can drop several $1,000's on these..but you need one in order to find the fish.
To bring a big fish onboard, invariably requires a gaff. A gaffed fish will bleed profusely and if you step on the gaff, you too will bleed profusely.
Then the fish needs a big iced down cooler before it spoils.
Filleting a fish on board is a messy business. You need a fish cleaning station and a constant stream of water
You can catch fish in 10' of water
or 1,000' of water....anchoring in 1,000' is a tad difficult.
I can burn several 100 dollars in fuel
costs for a single trip...and not catch any fish.
At the end of the day, catching fish is a sport.
I've always set out a few trolling rods behind my sailboat, but catch mostly barracuda if anything at all.
Most importantly :
You can buy fresh fish at the fish market for a fraction of the cost and hassle.
