Altura 1101 (Polaris 37)
Description
The Altura 1101 (often called Altura 1101 Polaris 37 or simply Polaris 37 (Altura 1101)) is a classic Italian fiberglass performance cruiser/racer from the early 1980s, built by the Polaris yard (or associated builders) around 1983–1985. It's essentially a production derivative/adaptation of Ron Holland's renowned Swan 371 design (a highly successful IOR-influenced cruiser-racer from Nautor Swan, 1979–1984), sharing the same hull lines, underwater profile, and overall performance DNA but with a more affordable build and some deckhouse/cabin tweaks for cruising comfort. Ron Holland's touch shines through: fast, balanced, and seaworthy with clean, elegant lines—great upwind speed, responsive handling, and a reputation as a "timeless one-tonner" style boat (though not a strict IOR one-tonner). It's praised in classic boat circles (e.g., Giornale della Vela) as one of the beautiful "old ladies" from that era—better performing and more harmonious than some contemporaries, with good motion comfort for coastal/offshore use. Examples like "Daphne" highlight its enduring appeal.
