iPolar
Estimate cruising-yacht performance polars from a small set of vessel dimensions.
Useful for comparing modelled performance before independent validation
Sail configurations yield graph/table outputs and a Weather4D Pro handoff.
Keep in mind: Limited to described eight-to-twenty-metre cruising monohulls; unusual hull/sail ratios reduce accuracy, so estimates are not safe-weather or routing guarantees.
