Oceanco Alfa G 2004 vs Oceanco Luna B 2005 — Same Brand, Different Boat

The Oceanco Alfa G 2004 vs Oceanco Luna B 2005 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 Oceanco Luna B 2005 measures 217,0 feet overall (2005), giving it roughly 20,0 additional feet of deck space compared to the Oceanco Alfa G 2004 at 197,0 feet (2004). Weight tells a clearer story for trailering families: the Oceanco Luna B 2005 tips the scales at 3 602 000 lbs — 1 202 000 lbs less than the Oceanco Alfa G 2004 at 2 400 000 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 power gap is worth calling out. Rated to 3 015 hp, the Oceanco Luna B 2005 has a 1 365-hp advantage over the Oceanco Alfa G 2004's 1 650-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Oceanco Alfa G 2004 carries 34 078 gallons versus 4 755 gallons in the Oceanco Luna B 2005. 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 Oceanco Luna B 2005 is rated for 66 passengers, while the Oceanco Alfa G 2004 caps at 60. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Oceanco Luna B 2005 could be the deciding factor.

Bottom line: Choose the Oceanco Luna B 2005 if your priority is putting more people on the water — it handles 66 passengers and at 217,0 ft it has the deck room to back that rating up comfortably. The Oceanco Alfa G 2004 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 60 that costs less to run day-to-day.

Oceanco Alfa G 2004 vs Oceanco Luna B 2005 — Common Questions

Which is the larger boat — the Oceanco Alfa G 2004 or the Oceanco Luna B 2005?
The Oceanco Luna B 2005 is the longer of the two at 217,0 feet overall. The Oceanco Alfa G 2004 comes in at 197,0 feet, making it roughly 20,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Oceanco Alfa G 2004 or the Oceanco Luna B 2005?
For trailering, the Oceanco Alfa G 2004 has the edge at 2 400 000 lbs dry weight versus 3 602 000 lbs for the Oceanco Luna B 2005. Add a motor (typically 300–500 lbs for an outboard in this class), gear, and a partial fuel load and the difference grows. Lighter is friendlier on smaller tow vehicles and on fuel economy while hauling.
Which boat can handle a bigger outboard?
The Oceanco Luna B 2005 is rated to a maximum of 3 015 hp, giving it the larger power ceiling. The Oceanco Alfa G 2004 tops out at 1 650 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 Oceanco Alfa G 2004 is Coast Guard rated for 60 passengers, while the Oceanco Luna B 2005 is certified for 66. 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 is wider, and does it affect trailering?
The Oceanco Luna B 2005 measures 468" wide, compared to 408" for the Oceanco Alfa G 2004. The US standard-width towing limit is 8’6" (102") in most states — anything over that may need a wide-load permit. Confirm your specific route requirements with each state's DOT.
Which boat has the larger fuel tank — the Oceanco Alfa G 2004 or the Oceanco Luna B 2005?
The Oceanco Alfa G 2004 has the bigger tank at 34 078 gallons, versus 4 755 gallons on the Oceanco Luna B 2005. That 29323-gallon difference translates to roughly 87969–146615 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Oceanco Alfa G 2004 and Oceanco Luna B 2005 from the same manufacturer?
Yes — both the Oceanco Alfa G 2004 and the Oceanco Luna B 2005 are built by Oceanco. 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.
