The Bertram 31 Flybridge Cruiser 1974 vs Bertram 35 2020 comparison sits squarely in the category of decisions where specs alone won't tell the whole story — intended use, storage, and long-term ownership costs all factor in.
Size is the most obvious dividing line here. The Bertram 35 2020 measures 35,1 feet overall (2020), giving it roughly 4,1 additional feet of deck space compared to the Bertram 31 Flybridge Cruiser 1974 at 31,0 feet (1974). Weight tells a clearer story for trailering families: the Bertram 35 2020 tips the scales at 20 789 lbs — 10 189 lbs less than the Bertram 31 Flybridge Cruiser 1974 at 10 600 lbs. That difference is meaningful if you're working within a half-ton or three-quarter-ton truck's tow rating, especially once you factor in a motor, gear, and fuel.
The Bertram 31 Flybridge Cruiser 1974 carries a rated maximum of 140 hp. Engine data for the Bertram 35 2020 wasn't available in our records — check the manufacturer's spec sheet before sizing a motor.Fuel capacity breaks the other way: the Bertram 31 Flybridge Cruiser 1974 carries 225 gallons versus 31 gallons in the Bertram 35 2020. On a lake day that's negligible, but for coastal cruising or long reservoir runs the extra range matters.
For family outings this is probably the sharpest distinction between the two. The Bertram 35 2020 is rated for 10 passengers, while the Bertram 31 Flybridge Cruiser 1974 caps at 9. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Bertram 35 2020 could be the deciding factor.
Bottom line: Choose the Bertram 35 2020 if your priority is putting more people on the water — it handles 10 passengers and at 35,1 ft it has the deck room to back that rating up comfortably. The Bertram 31 Flybridge Cruiser 1974 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 9 that costs less to run day-to-day.
