Tiara Yachts 3800 Open 2007 vs Tiara Yachts 4200 Open 2007 — Same Brand, Different Boat

The Tiara Yachts 3800 Open 2007 vs Tiara Yachts 4200 Open 2007 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 Tiara Yachts 4200 Open 2007 measures 44,0 feet overall (2007), giving it roughly 40,0 additional feet of deck space compared to the Tiara Yachts 3800 Open 2007 at 4,0 feet (2007). At 226 lbs and 286 lbs respectively, both sit in a similar weight class — either should pair comfortably with most mid-size SUVs and half-ton trucks, though always confirm your specific tow rating with the motor added.

The power gap is worth calling out. Rated to 715 hp, the Tiara Yachts 4200 Open 2007 has a 225-hp advantage over the Tiara Yachts 3800 Open 2007's 490-hp ceiling — enough to notice on acceleration and at cruising speed, particularly with a full passenger load. Fuel capacity breaks the other way: the Tiara Yachts 3800 Open 2007 carries 411 gallons versus 52 gallons in the Tiara Yachts 4200 Open 2007. 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 Tiara Yachts 4200 Open 2007 is rated for 13 passengers, while the Tiara Yachts 3800 Open 2007 caps at 12. If you're regularly pulling extended family or a group of friends onto the water, the extra seats on the Tiara Yachts 4200 Open 2007 could be the deciding factor.

Bottom line: Choose the Tiara Yachts 4200 Open 2007 if your priority is putting more people on the water — it handles 13 passengers and at 44,0 ft it has the deck room to back that rating up comfortably. The Tiara Yachts 3800 Open 2007 is the smarter pick if you want a lighter, easier-to-trailer boat rated for 12 that costs less to run day-to-day.

The Tiara Yachts 4200 Open 2007 is the longer of the two at 44,0 feet overall. The Tiara Yachts 3800 Open 2007 comes in at 4,0 feet, making it roughly 40,0 ft shorter — a meaningful difference in deck room and overall on-water presence.
Which is easier to trailer — the Tiara Yachts 3800 Open 2007 or the Tiara Yachts 4200 Open 2007?
For trailering, the Tiara Yachts 3800 Open 2007 has the edge at 226 lbs dry weight versus 286 lbs for the Tiara Yachts 4200 Open 2007. 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 Tiara Yachts 4200 Open 2007 is rated to a maximum of 715 hp, giving it the larger power ceiling. The Tiara Yachts 3800 Open 2007 tops out at 490 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 Tiara Yachts 3800 Open 2007 is Coast Guard rated for 12 passengers, while the Tiara Yachts 4200 Open 2007 is certified for 13.

Which boat is wider, and does it affect trailering?
The Tiara Yachts 4200 Open 2007 measures 179" wide, compared to 17" for the Tiara Yachts 3800 Open 2007. 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.
