Bertram 50 Open Open 2020 vs Bertram MOPPIE 1983 — Same Brand, Different Boat

The Bertram 50 Open Open 2020 vs Bertram MOPPIE 1983 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 1 110 hp, the Bertram 50 Open Open 2020 has a 1 104-hp advantage over the Bertram MOPPIE 1983's 6-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 50 Open Open 2020 carries 1 236 gallons versus 135 gallons in the Bertram MOPPIE 1983. 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 50 Open Open 2020 is rated for 15 passengers, while the Bertram MOPPIE 1983 caps at 7. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Bertram 50 Open Open 2020 could be the deciding factor.

Bottom line: Choose the Bertram 50 Open Open 2020 if your priority is putting more people on the water — it handles 15 passengers and at 49,9 ft it has the deck room to back that rating up comfortably. The Bertram MOPPIE 1983 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 7 that costs less to run day-to-day.

Bertram 50 Open Open 2020 vs Bertram MOPPIE 1983 — Common Questions

Which is the larger boat — the Bertram 50 Open Open 2020 or the Bertram MOPPIE 1983?
The Bertram 50 Open Open 2020 is the longer of the two at 49,9 feet overall. The Bertram MOPPIE 1983 comes in at 26,0 feet, making it roughly 23,9 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which boat can handle a bigger outboard?
The Bertram 50 Open Open 2020 is rated to a maximum of 1 110 hp, giving it the larger power ceiling. The Bertram MOPPIE 1983 tops out at 6 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.
How many people can each boat hold?
The Bertram 50 Open Open 2020 is Coast Guard rated for 15 passengers, while the Bertram MOPPIE 1983 is certified for 7. 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.
Which boat has the larger fuel tank — the Bertram 50 Open Open 2020 or the Bertram MOPPIE 1983?
The Bertram 50 Open Open 2020 has the bigger tank at 1 236 gallons, versus 135 gallons on the Bertram MOPPIE 1983. That 1101-gallon difference translates to roughly 3303–5505 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Bertram 50 Open Open 2020 and Bertram MOPPIE 1983 from the same manufacturer?
Yes — both the Bertram 50 Open Open 2020 and the Bertram MOPPIE 1983 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.
