Compromis 909 Buyer's Guide
Shopping the used Compromis 909 means looking at a 31-foot Frans Maas–designed masthead sloop from Jachtwerf Zaadnoordijk BV, produced from 1985 within the Dutch builder's GRP cruiser lineage. These are solid-hulled coastal boats with a fin keel, not performance racers, and the brokerage stock reflects that cruising intent rather than any race-track pedigree.
Layouts on the Used Market
The 909 came with seven berths as standard, so most boats you meet will show a family-oriented interior rather than a stripped racer. Expect a beamy hull at just over 11 feet width and a shallow fin drawing about 4 feet, which lets many examples sit in modest marinas that deeper keelboats cannot enter. Tankage runs to 66 gallons of water and 18 of diesel — adequate for coastal use but worth confirming against your plans before a long passage.
Equipment and Common Upgrades
Power comes from an inboard diesel, either a Yanmar 27D rated at 18 horsepower or a 24-horsepower unit, both driving through a saildrive. For a buyer, the saildrive means budgeting for periodic seal service and keeping a spare diaphragm aboard. Rigging is masthead sloop; sheet lengths are generous, with the mainsheet at 76.7 feet and spinnaker sheets at 67.5 feet, so confirm existing lines are sound or renew them before the first offshore leg.
What to Inspect
The saildrive transmission is the item most likely to need attention on a used 909 — inspect the seal and diaphragm for weeping or corrosion. The solid fiberglass hull and 301-square-foot wetted surface should be checked for ordinary osmosis or impact damage from groundings in thin water.
Availability and Buyer's Takeaway
For a buyer, the short checklist is: verify saildrive seal condition, confirm seven-berth layout suits your crew, and check the diesel and tankage. The 909 remains a sensible, well-found Maas cruiser for the right owner who values simple, proven construction over headline performance.
