This Spring, the UBC Sailbot team advanced POLARIS through a series of critical engineering milestones that solidified the foundation for our upcoming testing season.

The mechanical team, the started with the KEEL ASSEMBLY, a structural anchor essential for stability and performance. The team then completed SAIL DEMOLDING and TRIM-TAB DEREMELING, refining aerodynamic surfaces for accuracy and responsiveness. Progress continued with RIBS FABRICATION AND ASSEMBLY, followed by the RUDDER LAYUP, each step contributing to the hydrodynamic efficiency of the hull. We also received our SOLAR PANELS, enabling us to progress toward integrated energy systems. A key milestone was the PILOT BUILD OF SAIL WITHIN HULL, where we verified mechanical fitment ahead of final installation and concluded with PAINTING THE BOAT, transforming structural work into a finished, test-ready platform.
