Most Popular Great Loop Boats Ranked by Real Cruisers
Introduction
Don't buy a Great Loop boat until you see this data.
Most people planning the Great Loop spend months researching boats. They go to the shows, they read the forums, they watch the reviews, and then they make a purchase based on what sounds right — based on reputation, aesthetics, and what other people seem to be buying.
But here's the thing nobody tells you at the boat show.
The boats that sound right and the boats that finish the Loop are two very different lists.
Today, we're going to look at the actual completion data — the brands whose boats crossed every lock and completed every mile — and use it to reframe how you should be shopping, because the numbers are going to surprise you.
What the Data Is and Why It Matters
Every year, the American Great Loop Cruisers’ Association provides a summary of self-reported Great Loop completions.
The most common brands of boats that completed the Loop in 2025 will likely surprise you.
What we have is a direct read on real-world performance across 6,000 nautical miles, 23 states, two countries, and some of the most varied inland waterway conditions in North America.
I call this the Loop Proven Data Set, and it's the closest thing to an unfiltered performance record that Great Loop buyers have access to.
Now, you're probably thinking, “Completions are just volume. Of course, the most popular brands show up more!”
And that's the right instinct to have. We're going to address that head-on.
But when you see which brands dominate the top of this list and which well-known brands are missing, the volume argument doesn't hold up the way you'd expect.
Here is what the data actually shows.
The brands with the highest completion counts are not the ones with the loudest reputations or the highest price tags. They're the ones built around range, repairability, and community support.
Let's go through them.
The Most Popular Boat Brands That Completed the Great Loop in 2025
There were 272 vessels that reported crossing their wake in 2025.
And with an average completion time of 653 days, it's worth noting that the majority of these Loopers had started their Loop in 2024 or prior.
The average boat size was just over 41 feet.
And here are the most popular boat makes that completed the Great Loop in 2025:
Mainship
Carver
Grand Banks
Sea Ray
Cruisers
Beneteau
Kadey-Krogen
Bayliner
Monk
Nordic Tug
Ranger Tug
The Proven Brands: What the Expected Names Confirm
The brands that will not surprise you on this list are Kadey-Krogen and Grand Banks.
Both show up with solid completion numbers, and both are there for exactly the reasons you'd expect.
These are purpose-built passagemakers. Heavy-displacement or semi-displacement hulls, full keel, designed from the ground up for this kind of voyage.
The parts ecosystem is mature. The community knows how to fix them, and they've earned their reputation over decades.
But don't let that reputation do your work for you.
Grand Banks boats on the used market often carry significant deferred maintenance. A neglected Grand Banks will hurt you just as badly as any boat that wasn't designed for long-range passage.
A proper marine survey is not optional on these. It's the first thing you do before any other conversation.
The Brands That “Shouldn't” Be Here — But Are
Here is where the data starts to get interesting.
Bayliner, Sea Ray, Cruisers Yachts, and Beneteau.
These are clearly not full-displacement trawlers, and yet they all show meaningful Loop completion numbers.
Bayliner is an entry-level brand. Sea Ray and Cruisers Yachts are planing-hull express cruisers. They're fast, fuel-hungry, and built for weekends on the water.
Beneteau manufactures express cruisers and semi-displacement fast trawlers.
What this tells you is that the Great Loop is not a trawler-only voyage.
Hull type matters less than most buyers assume.
What those completions represent is preparation, range management, mechanical readiness, and a captain who respected the voyage.
The mistake buyers make is treating a traditional trawler as a prerequisite.
The data says otherwise.
The Two Brands That Change How You Shop
Most people shopping for a Great Loop boat will filter for the names they recognize and move on.
But actually, the brands at the top of this list are the ones most buyers either overlook or have already dismissed.
Carver: 20 Great Loop Completions
Carver comes in at 20 Loop completions in 2025.
Twenty!
Carver boats are American-made fiberglass, twin-engine motor yachts built in high volume from the 1970s through the early 2000s.
They were never the most prestigious name at the dock, but 20 Loop completions is not an accident. It's a track record.
What makes Carver so well suited to this voyage is exactly what makes buyers hesitate.
They're abundant and affordable.
That means three things that matter when you're 400 miles from the nearest dealer.
Parts are available.
There's a large community of owners who know these boats inside and out.
And because the used market is full of them, you don't have to stretch your budget to the edge just to acquire one, which means you have money left over for the voyage itself: spares, fuel, haul-outs, unexpected repairs.
The mistake buyers make with Carver is assuming that affordable signals “not serious.”
Twenty completions say otherwise.
Mainship: The Most Proven Great Loop Brand in the Country
Here is what most buyers never find out.
The brand with more Loop completions than any other in 2025 is not Kadey-Krogen.
It's not Grand Banks.
It's not Sea Ray.
It's Mainship.
At 29 completions, Mainship doesn't just lead this list; it dominates it. The next closest brand has nine fewer completions.
That margin is not a coincidence.
Mainship built semi-displacement trawlers from the late 1970s through 2013.
They were designed to be affordable, fuel-efficient, and, critically, easy to maintain by an owner with modest mechanical skills.
They were never glamorous.
They fit the bill as far as livability and storage capacity.
In a marina full of Grand Banks and Nordhavns, a Mainship is the quiet boat in the corner that nobody photographs.
But the Great Loop does not reward glamour.
It rewards reliability, range, and repairability.
And Mainship delivers on all three consistently at a price point that most first-time Loopers can actually reach.
You're probably thinking, “But isn't this just because there are more Mainships out there?”
Fair question.
But Grand Banks has a massive base, too, and so does Sea Ray.
The numbers still favor Mainship by a wide margin.
This isn't a volume story; it's a suitability story.

What the Great Loop Completion Data Is Actually Telling You
The Loop Proven Data Set isn't a shopping list. It's a lens.
And once you look through it, a few things become impossible to ignore.
Brand Reputation Is the Wrong Filter
The brands with the most completions are not the most prestigious brands in recreational boating.
They're the ones that are practical, supported, and affordable enough to leave a budget for the trip itself.
Hull Type Is a Secondary Variable
Sea Ray and Cruisers Yachts finishing the Loop in meaningful numbers means that a planing hull with a prepared captain beats a trawler with a captain who didn't plan for fuel range.
Budget Brands Are Not Disqualified
Bayliner. Carver. Mainship.
These are not the boats on the cover of the magazines.
They are, however, on the water at the finish line.
And the biggest mistake you can make going into this purchase is letting a showroom floor or a forum full of opinions talk you out of a boat with a proven completion record, or into a boat with a prestigious name and scary price tag.
Turning the Great Loop From a Dream Into a Plan
The Great Loop will test your vessel for months, possibly years, along the journey of 6,000 nautical miles.
It will find every weakness in your boat and every gap in your preparation.
The brands that show up most on the completion side of the equation are not the ones that look best in a brochure.
They're the ones that are built to move, built to be fixed, and built to be affordable enough that you finish the voyage with something left in the bank.
When you put the Loop Proven Data Set next to your shortlist and you can see a name like Mainship or Carver staring back at you, take it seriously.
That data was earned one lock at a time.
And when you find the right boat, when you get the survey done, when you build your float plan, when you've got a realistic fuel and maintenance budget, that's when the Loop stops being a dream and starts being a plan.
