Saxdor 400 GTS (2026-)
2 x 425-hp Mercury V10
Brief Summary
You may not be familiar with the Saxdor name but the Finland, Helsinki-based builder has been on the scene long before its founding in 2019. For it was its visionary founder, designer Sakari Mattila, the force behind such acclaimed and award-winning brands as Aquador (1994), Paragon (2003), XO (2008), and Axopar (2012), who decided it was time to focus on his own concept.
The Saxdor 400 GTS, one of many in the model lineup, is the culmination of years of design and engineering pioneered by Mattila and presents an exciting open boat with the ability to provide more than a day out on the water. A suitable forward berth and head, along with an aft stateroom, which can double as a large storage space, combines with just the right balance of twin outboard power and a long list of amenities to make an expanded overnight, or weekend stay within easy planning.

Vessel Inspection
With a beam of 11’8”, the Saxdor 400 GTS has been designed with its helm carrying that dimension until narrowing down some at the bow. This provides a wider space topsides as well as in the forward cabin and head.
Bow
Generous attention was placed on the bow with plenty of room for seating and storage.
Helm
The helm is located on the centerline and offers excellent views into the seaway through large windows.
Cockpit
The Saxdor 400 GTS defines what an open boat can be. With the right conditions prevailing, a day out on the water becomes something really special.
Aft
As we discovered, the Saxdor 400 GTS, with its Scandinavian sensibility and vision, is the kind of boat whose personality is totally geared towards providing adventure and excitement while out on the water.
Cabin
While the Saxdor 400 GTS fulfills her dayboat profile, she does have a cabin and head quite suitable for weekend travel as well as taking some extended time away.
A Word About Performance
Our test boat was outfitted with pair of 425-hp Mercury V10 outboards turning Mercury Revolution 14.6 x 21” pitch props. We calculated a test weight of approximately 16,720 pounds with 98% of the total fuel capacity of 238 gallons. There were four people on board and the local conditions saw an air temperature of 76°, relative humidity of 66%, and a calm seaway with 10 knots of wind.
At 6500 rpm we hit our top speed of 55.8 mph. we settled into our best cruise at 4500 rpm where we noted a 36.2 rate of speed and a range of 308.5 statute miles with a 10% fuel reserve. Hole shot tests were exciting with 0-10 mph is 3.5 seconds, 0-20 in 7.5 seconds, 0-30 in 11.5 seconds, and 0-40 in 17.0 seconds. She welcomed sharp turns in a sporty manner and proved to be a pleasure, with a fair amount of excitement thrown in, to drive. Control under power and confidence at the wheel were the gifts we received during our time aboard the Saxdor 400 GTS.
Summary
A pleasure to look at, an exciting experience to drive. The Saxdor 400 GTS is all that and a lot more.
