Bertram 37 Convertible 1987 vs Bertram 41 Convertible 2011 - Boat Spec Comparison

Q: Which is the larger boat — the Bertram 37 Convertible 1987 or the Bertram 41 Convertible 2011?

The Bertram 41 Convertible 2011 is the longer of the two at 41,0 feet overall. The Bertram 37 Convertible 1987 comes in at 37,0 feet, making it roughly 4,0 ft shorter — a meaningful difference in deck room and overall on-water presence.

Q: Which boat can handle a bigger outboard?

The Bertram 41 Convertible 2011 is rated to a maximum of 600 hp, giving it the larger power ceiling. The Bertram 37 Convertible 1987 tops out at 375 hp. Keep in mind that maximum ratings are just that — matching the motor to the actual load and usage pattern usually matters more than chasing the ceiling.

Q: How many people can each boat hold?

The Bertram 37 Convertible 1987 is Coast Guard rated for 11 passengers, while the Bertram 41 Convertible 2011 is certified for 12. Note that legal capacity and comfortable capacity aren't always the same thing — on a full day out, most experienced boaters aim for about 80% of the rated number to keep things comfortable.

Q: Which boat has the larger fuel tank — the Bertram 37 Convertible 1987 or the Bertram 41 Convertible 2011?

The Bertram 41 Convertible 2011 has the bigger tank at 54 gallons, versus 47 gallons on the Bertram 37 Convertible 1987. That 7-gallon difference translates to roughly 21–35 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.

Q: Are the Bertram 37 Convertible 1987 and Bertram 41 Convertible 2011 from the same manufacturer?

Yes — both the Bertram 37 Convertible 1987 and the Bertram 41 Convertible 2011 are built by Bertram. That means shared dealer networks, common parts availability, and consistent build quality across the line. The choice between them is essentially a question of how much boat you need, not which brand you trust.

Detailed Evaluation & Buyer Recommendation

Bertram 37 Convertible 1987 vs Bertram 41 Convertible 2011 — Same Brand, Different Boat

The Bertram 37 Convertible 1987 vs Bertram 41 Convertible 2011 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.

The power gap is worth calling out. Rated to 600 hp, the Bertram 41 Convertible 2011 has a 225-hp advantage over the Bertram 37 Convertible 1987's 375-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Bertram 41 Convertible 2011 carries 54 gallons versus 47 gallons in the Bertram 37 Convertible 1987. 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 41 Convertible 2011 is rated for 12 passengers, while the Bertram 37 Convertible 1987 caps at 11. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Bertram 41 Convertible 2011 could be the deciding factor.

Bottom line: Choose the Bertram 41 Convertible 2011 if your priority is putting more people on the water — it handles 12 passengers and at 41,0 ft it has the deck room to back that rating up comfortably. The Bertram 37 Convertible 1987 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 11 that costs less to run day-to-day.
