Hull explorer

Three views of the same hull, generated live from the table of offsets. The upper slider walks a station fore and aft; the lower one moves a waterline up and down. Arrow keys work too — hold shift for bigger steps.

How to read these

The profile is the boat from the side: the sprung sheer, the spoon stem, the straight run into the integral stern platforms, the deckhouse and the solar roof carried aft on posts. The dashed orange lines are the two working chines seen edge-on; the gold line at 130 mm above the waterline is the boot seam, which is a plywood joint doing duty as a design line. Dotted blue verticals are watertight bulkheads.

The section is the shape a saw would leave if you cut the demihull across at the marked station. Faint grey sections behind it are the ten tabulated stations, so you can see where the current cut sits in the family. Four strakes per side means five points: keel, chine 1, chine 2, boot seam, sheer — and between them, straight lines, because the hull really is made of flat panels.

The plan is both demihulls from above, with the current waterline drawn heavy through each. Drag the lower slider down and watch the waterline shrink toward the keel; drag it up past 130 mm and it jumps out to the boot seam and then the flare. That jump is the shape of the boat.

Everything here comes from lines plan SW-LP01 Rev 0a, and the same data drives the drawing sheets.
