The weight of a fishing boat is not something that answers for all… It depends on the kind of work that you do. The size of the body plays a big role.
Also the material affects that. And later come the tools, fuel and gear that you load up. A little and lightweight boat that sails coastal water can reach only some hundred pounds on the scale.
How Much Do Fishing Boats Weigh
On the other hand a massive trawler for deep sea, built to last severe oceans? That can easily pass 50 tons. The difference is truly surprising.
For the most common fishing boats that you will meet, typical full gear with engine and trailer weigh around 3 500 pounds. The whole range usually sits between 2 800 and 5 000 pounds, when everything is tied. Remove the trailer, and the boat with engine alone reaches under 3 000 pounds.
Replace the trailer and your whole gear, and you add yet 500 to 1 000 pounds quite quickly.
A smaller boat will naturally be more lightweight. A ten-foot boat from aluminum can weigh around 100 to 150 pounds, ideal for solo trips on small waters. Jon Boats weigh around 660 pounds.
I saw a 17-foot aluminum fishing boat with dry weight of 850 pounds, and when fully loaded, it reached under 2 000 pounds entirely. A sixteen-foot sailboat with its trailer weighed combined around 540 pounds.
Fiberglass boats in the range of 16 to 20 feet weigh between 1 700 and 2 900 pounds. Add a heavy trailer below, and the whole towing wait can reach 5 000 pounds without big troubles. Models from the middle of the 1980s in the same size commonly had dry weight of 2 500 to 3 500 pounds, depending mostly on the engine and extras that came with it.
The weight grows surprisingly quickly for bigger models. I measured a 22.5-foot boat with a 175 horsepower engine, helper motor, full fuel tank and loaded with tools, it reached 4 750 pounds on the scale. Another 22-foot with a tunnel body, with a 200 horsepower engine and full gear, marked 5 900 pounds.
One old 30-foot boat that I know had double 150 horsepower engines, five batteries, 130 gallons of fuel and a 1 700-pound trailer… The whole setup passed 9 500 pounds.
Commercial fishing boats live in an entirely other heavy world. Small to mid-sized commercial setups go from 8 000 pounds to above 50 000. Inland trawlers and sea boats between 30 and 45 feet usually weigh from 8 000 to 25 000 pounds.
Anything more than 50 feet for foreign trips can reach 20 000 to well above 100 000 pounds.
Precise towing comes down to knowing your weight well. The best step is to go to a truck scale and get real weight with the trailer attached. It costs around five dollars, but gives you a reliable number instead of guessing.
That is moreimportant than one thinks, especially when you are pulling a heavy load.
