The Alo 33 is a distinguished 32.74-foot masthead sloop, born from the ambitious collaboration between Norwegian builder Alo Yachts and designer Jan Bjerke, alongside company founder Alf Ortang. Conceived in the mid-1970s, this vessel was initially envisioned as an International Offshore Rule (IOR) 3/4 tonner, aiming for racing success while simultaneously offering the versatility of an all-purpose cruising yacht. Built by Alo Yachts, a company known for its practical ingenuity and robust Scandinavian boatbuilding ethos, the Alo 33 embodies a blend of performance aspirations and solid construction.

History and Design
Production of the Alo 33 commenced in 1975 and concluded in 1980, with approximately 45 units built during its run. The creation of the Alo 33 marked a significant step for Alo Yachts, following their successful Alo 28. Founder Alf Ortang's objective was to introduce a larger, more performance-oriented model to their clientele. This led to the partnership with Jan Bjerke, a designer who had previously worked with Pelle Petterson, with the explicit brief of developing a competitive IOR 3/4 tonner for the 1976 world championships. While Bjerke initially conceived a fast IOR racer, the collaboration aimed to fuse this racing prowess with an all-purpose vessel suitable for various sailing endeavors. Alo Yachts, under Ortang's guidance, consistently emphasized durability and seaworthiness, traits that are evident in the solid fiberglass hull construction of the Alo 33.
Sailing Performance and Handling
With a design that sought to balance racing ambition with cruising comfort, the Alo 33 exhibits sailing characteristics indicative of its IOR heritage and robust build. The boat's Sail Area to Displacement (SA/D) ratio of approximately 15.05 suggests that while capable, it is generally considered a heavy sailboat that may be slightly underpowered in lighter air. However, its Ballast to Displacement ratio of around 38.77% indicates good stiffness and stability, allowing the boat to stand up well to a breeze and providing a comfortable motion in a seaway. Furthermore, a Displacement to Length (D/L) ratio of approximately 323.8 places the Alo 33 firmly in the category of a heavier, more traditional cruiser, emphasizing stability over outright speed.
Owners often describe the Alo 33 as a stable and stiff vessel with good righting capability. Its masthead sloop rig offers simplicity in handling, while the fin keel design contributes to splendid maneuverability. These characteristics make the Alo 33 a reliable and predictable boat to sail, particularly appealing for coastal cruising or even extended periods aboard.
Accommodations and Layout
The interior of the Alo 33 is designed for practicality and comfort, reflecting its role as a well-built Scandinavian yacht suitable for cruising. While specific headroom measurements are not readily available in detailed specifications, owners often note the spacious saloon and cabins, making it suitable for extended stays aboard. The typical layout includes at least one cabin and is configured to accommodate up to eight berths. Essential amenities for cruising are present, such as a galley and a head. Examples of the Alo 33 commonly feature a refrigerator with freezer and a stove with oven, enhancing its liveaboard potential. The boat's water capacity is 32 gallons, supporting longer periods away from shore. The emphasis on robust construction extends to the interior, where practical materials and a functional arrangement prioritize utility and durability.
