Maxum 1800 SR3 2008 vs Maxum 3700SY Sport Yacht 2005 — Common Questions

Which is easier to trailer — the Maxum 1800 SR3 2008 or the Maxum 3700SY Sport Yacht 2005?
For trailering, the Maxum 1800 SR3 2008 has the edge at 25 lbs dry weight versus 178 lbs for the Maxum 3700SY Sport Yacht 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.
What is the maximum horsepower rating for these boats?
The Maxum 1800 SR3 2008 has a documented max rating of 220 hp. Engine specifications for the Maxum 3700SY Sport Yacht 2005 were not available in our database — check the OEM spec sheet or manufacturer's website for confirmation.
How many people can each boat hold?
The Maxum 1800 SR3 2008 is Coast Guard rated for 5 passengers, while the Maxum 3700SY Sport Yacht 2005 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.
Which boat is wider, and does it affect trailering?
The Maxum 3700SY Sport Yacht 2005 measures 156" wide, compared to 91" for the Maxum 1800 SR3 2008. 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.

The Maxum 1800 SR3 2008 has the bigger tank at 28 gallons, versus 3 gallons on the Maxum 3700SY Sport Yacht 2005. That 25-gallon difference translates to roughly 75–125 nautical miles of additional range at cruising speed, depending on motor, load, and conditions.
