Design and Construction
The 909 stretches 29.53 feet overall on a 24.61-foot waterline, with a beam of 10.1 feet that gives her a length-to-beam ratio of 2.91 — a relatively broad-bodied nine-meter boat. Displacement sits at 7,055 pounds, of which 2,976 pounds is cast-iron ballast for a ballast ratio of 42 percent, and the hull carries a fin-with-bulb profile with a spade rudder. That combination, with a displacement-to-length ratio of 226, places her among what one design summary calls "moderate racers" rather than pure cruisers or out-and-out racers. The wetted surface runs about 290 square feet, and immersion is roughly 869 pounds per inch, so she loads and trims in a predictable, measurable way. Petterson offered the boat with more than one keel: a wing-keel version and a torpedo-keel version both exist, and the iron keel is the same material regardless of profile. Draft is listed at 5.41 feet for the bulb configuration, with period notes suggesting the loaded draft can range to about 5.71 feet depending on how the boat sits.
Rig and Handling
The fractional sloop rig carries a reported sail area of 404 square feet. On the ISO 8666 reference sail that yields a sail-area-to-displacement ratio of 16.0; hoist a 135-percent genoa and the figure rises to 18.3, which explains why the boat feels lively upwind without becoming over-canvased. The theoretical displacement-hull speed works out to 6.65 knots, and under the Volvo Penta 2001 nine-horse diesel with saildrive the boat makes 6.0 knots — close enough to hull speed under power to make a marina exit undramatic. The capsize screening value is 2.02, a number that, as the period review noted, would bar her from ocean-racing acceptance, though her Motion Comfort Ratio of 19.0 to 21.6 puts her in a tolerable seaway for coastal cruising. The shallow-ish draft and spade rudder make her a straightforward boat to dock and to bring into most marinas.
Accommodations
Inside, the interior is teak, finished in the standard production style of the era rather than as a custom joinery job. The 24-gallon water tank and 9-gallon diesel tank reflect the boat's weekender-and-coastal-cruiser intent: enough to roam for a few days without resorting to jerry cans. The broad beam pays off below in usable cabin volume for a boat of this length, though the sources describe the interior in general terms rather than itemizing berths or the galley footprint. What is clear is that the 909 was conceived as a small family cruiser-racer, not a minimalist racer or a heavy-displacement voyager.
Known Issues
The iron keel is vulnerable to corrosion if bedding and coating are neglected, and the several keel options mean a given hull must be identified by its actual profile rather than assumed. The saildrive transmission on the Volvo Penta 2001 is a known service point on any such installation, with its rubber seal a periodic replacement item. The capsize screening value of 2.02 simply confirms she is a coastal boat, not a bluewater candidate, and should be treated as such.
Refits and Ownership
With production ended in 1991 and only 210 built, the 909 occupies a modest niche in the Maxi lineage. Petterson's hand is visible throughout, and the solid fiberglass hull and deck are straightforward to survey and repair. The nine-horse Volvo Penta 2001 is a well-supported small diesel, and the fractional rig is simple to reconfigure with a larger genoa if a previous owner has not already done so. Ownership costs stay low by virtue of the boat's size and the maturity of her systems.
The Verdict
The Maxi 909 is a Petterson-designed coastal cruiser-racer of modest production that rewards an owner who wants a predictable, well-mannered nine-meter boat without the complexity of a later-generation performance hull. She is quick enough under sail and power to be fun, beamy enough to be comfortable, and simple enough to keep afloat on a reasonable budget.
Pros
- Broad beam and 42-percent ballast ratio give a stable, roomy coastal platform
- Fractional rig with 135% genoa lifts sail-area-to-displacement to 18.3 for lively sailing
- Solid fiberglass hull and deck, teak interior, simple Volvo Penta 2001 saildrive
Cons
- Capsize screening value of 2.02 limits her to coastal use, not ocean racing
- Iron keel demands corrosion vigilance; multiple keel options require positive identification
- Small 9-gallon fuel and 24-gallon water capacity suit only short-range cruising
