Bali Catamarans 4.2 2021 vs Bali Catamarans 4.5 2018 — Same Brand, Different Boat

The Bali Catamarans 4.2 2021 vs Bali Catamarans 4.5 2018 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.

On paper these two are close siblings in the size department — Bali Catamarans 4.2 2021 at 42,1 ft versus Bali Catamarans 4.5 2018 at 45,0 ft. Weight tells a clearer story for trailering families: the Bali Catamarans 4.5 2018 tips the scales at 36 155 lbs — 1 102 lbs less than the Bali Catamarans 4.2 2021 at 35 053 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.

Both boats share a closely matched power ceiling — 45 hp for the Bali Catamarans 4.2 2021 and 55 hp for the Bali Catamarans 4.5 2018. Real-world performance will come down more to which motor is actually bolted on, its load at the time, and whether it's a 4-stroke or 2-stroke setup. Fuel capacity breaks the other way: the Bali Catamarans 4.5 2018 carries 211 gallons versus 169 gallons in the Bali Catamarans 4.2 2021. 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 Bali Catamarans 4.5 2018 is rated for 13 passengers, while the Bali Catamarans 4.2 2021 caps at 12. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Bali Catamarans 4.5 2018 could be the deciding factor.

Both boats sit in a similar displacement bracket — 35 053 lbs for the Bali Catamarans 4.2 2021 and 36 155 lbs for the Bali Catamarans 4.5 2018. Comparable displacement means broadly similar seakeeping behaviour and load capacity, though hull form and ballast ratio will still produce noticeably different sailing characteristics.

Both boats draw a similar depth — 3,6 ft and 4,0 ft respectively. Marina access and anchorage options should be broadly equivalent between the two.

For auxiliary power the Bali Catamarans 4.5 2018 carries a 55-hp engine against 45 hp on the Bali Catamarans 4.2 2021. Motoring range and ability to punch through a foul current or enter a tight marina under power will favour the more powerful installation.

For extended cruising, water capacity matters: the Bali Catamarans 4.2 2021 carries 228 gallons versus 211 gallons on the Bali Catamarans 4.5 2018 — a significant advantage on longer passages where watermaker or provisioning stops aren't guaranteed.

Bottom line: The Bali Catamarans 4.5 2018 at 45,0 ft offers more living space, greater range, and a more substantial offshore capability. The Bali Catamarans 4.2 2021 at 42,1 ft is the easier, lower-cost option — simpler to crew and a strong choice for coastal and day sailing.

Bali Catamarans 4.2 2021 vs Bali Catamarans 4.5 2018 — Common Questions

Which is the larger boat — the Bali Catamarans 4.2 2021 or the Bali Catamarans 4.5 2018?
The Bali Catamarans 4.5 2018 is the longer of the two at 45,0 feet overall. The Bali Catamarans 4.2 2021 comes in at 42,1 feet, making it roughly 2,9 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Bali Catamarans 4.2 2021 or the Bali Catamarans 4.5 2018?
For trailering, the Bali Catamarans 4.2 2021 has the edge at 35 053 lbs dry weight versus 36 155 lbs for the Bali Catamarans 4.5 2018. 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 Bali Catamarans 4.5 2018 is rated to a maximum of 55 hp, giving it the larger power ceiling. The Bali Catamarans 4.2 2021 tops out at 45 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 Bali Catamarans 4.2 2021 is Coast Guard rated for 12 passengers, while the Bali Catamarans 4.5 2018 is certified for 13. 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 deeper draft — the Bali Catamarans 4.2 2021 or the Bali Catamarans 4.5 2018?
The Bali Catamarans 4.5 2018 has the deeper draft at 4,0 ft, versus 3,6 ft for the Bali Catamarans 4.2 2021. A deeper draft generally means better upwind performance and stability, but limits access to shallow anchorages and some marina berths. Always check the controlling depth of your home port and favourite cruising grounds before committing.
Is the Bali Catamarans 4.2 2021 or the Bali Catamarans 4.5 2018 better suited for offshore sailing?
For offshore work, displacement and construction are the primary indicators. The Bali Catamarans 4.5 2018 at 36 155 lbs displacement is the heavier, more load-carrying design — generally better suited to extended passages where seakeeping and provisioning capacity matter most. The Bali Catamarans 4.2 2021 at 35 053 lbs will typically be livelier and more responsive in lighter conditions.
Which boat is better equipped for long-distance cruising?
For extended passages, fresh water capacity is a key indicator of cruising readiness. The Bali Catamarans 4.2 2021 carries 228 gallons of fresh water compared to 211 gallons on the Bali Catamarans 4.5 2018 — a meaningful advantage when watermaker installations or port stops aren't guaranteed.
Which boat is wider, and does it affect trailering?
The Bali Catamarans 4.2 2021 measures 306" wide, compared to 292" for the Bali Catamarans 4.5 2018. 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 Bali Catamarans 4.2 2021 or the Bali Catamarans 4.5 2018?
The Bali Catamarans 4.5 2018 has the bigger tank at 211 gallons, versus 169 gallons on the Bali Catamarans 4.2 2021. That 42-gallon difference translates to roughly 126–211 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
Are the Bali Catamarans 4.2 2021 and Bali Catamarans 4.5 2018 from the same manufacturer?
Yes — both the Bali Catamarans 4.2 2021 and the Bali Catamarans 4.5 2018 are built by Bali Catamarans. 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.
