Behind every solid Nauticat lies a clear set of priorities. From the mid-1980s onward, the man who shaped those priorities was Finnish naval architect and boatbuilder Kaj Gustafsson.
Gustafsson joined Siltala Yachts (later Nauticat Yachts) in the early 1970s. He later became managing director and part-owner, and from the Nauticat 35 (1986) onward he designed virtually every new model the yard produced. His son Patrik worked alongside him in the later years.
What makes Gustafsson interesting for us is not just the boats he drew — it is the unusually clear philosophy he followed.
Safety first, then comfort, then performance
In a 2014 interview Gustafsson stated his priorities without hesitation:
“The number one is safety. Number two is safety. Number three is safety… and then comfort is coming.”
For him, safety and quality were inseparable. That meant:
- Single-skin solid GRP hulls (no foam or balsa coring below the sheer)
- Traditional shaft drives instead of saildrives
- Real teak interiors that “smell quality”
- Strong, conservative construction intended to last decades
He repeatedly pointed out that the sea itself has not changed for thousands of years. Therefore radical redesigns of proven boats are usually a mistake. On models that already worked well, he preferred small, evolutionary improvements based on real owner feedback and on his own sailing experience with his wife on a Nauticat 321.
What this philosophy looks like on the water
Gustafsson disliked boats that slam into waves. He preferred fuller, more seakindly bow sections and a motion that feels secure rather than lively. He also paid attention to heel angle — noting that many Nauticat buyers (especially the women who often made the final decision) did not want a boat that heeled dramatically.
The result is a range of boats that prioritise:
- A stable, predictable platform
- A warm, protective pilothouse
- The ability to keep going in rough conditions without exhausting the crew
These qualities are exactly what we experience on our own Nauticat 38, Maja. The same design DNA runs through the smaller classic models and the later flagship boats such as the Nauticat 441 and Nauticat 525.
Here are two videos from our channel that show how a Nauticat designed according to these principles actually behaves:

Sailing performance and keel types explained:
Evolution, not revolution
From the Nauticat 39 (1993) onward, Gustafsson gradually increased sail area, refined keels and rudders, and improved sailing characteristics. At the same time he deliberately kept the traditional Nauticat character: solid construction, a proper pilothouse, and a cosy wooden interior.
Later models such as the 37, 385, 441 and 525 still feel recognisably related to the earlier motorsailers, even though they sail better and have more modern detailing. That continuity is no accident — it is the direct result of Gustafsson’s refusal to throw away what already worked.
You can see the same solid, practical approach in the construction and systems of our own boat:

Why this philosophy still matters
Many modern production boats chase speed, light displacement or maximum interior volume at the expense of seakindliness and structural longevity. Gustafsson’s approach was the opposite: start with safety and comfort, then carefully improve performance within those limits.
For people over 50 who want to leave the hamster wheel and live aboard for real, this philosophy is highly relevant. A boat that feels secure in a blow, that has a warm pilothouse, and that is built to last is often more valuable than a few extra knots of boat speed.
That is why we keep documenting the practical realities of life on a classic Finnish motorsailer — the good, the imperfect, and the genuinely reassuring.
