Rotor Sail Thrust and Route Fuel Saving
Wired White v2 Estimate Flettner rotor thrust, electrical demand and route fuel savings from three wind conditions. Includes a thrust polar plot and animated Magnus-effect schematic.
Marine
Boats and ships: hull speed, powering and propeller pitch, fuel per trip, anchoring loads, sailboat stability, electric boat range, wind-assisted propulsion and the emission rules ships face. Every calc shows its method and sources.

Ship CII Rating, EU ETS and FuelEU Cost 2026–2030
Wired White v2 Forecast ship CII ratings, EU ETS allowance costs and FuelEU GHG penalties through 2030. Dated rules, separate reporting and surrender years, and annual rating boundaries.
Sailboat Stability Calculator: Heel, Reefing and GZ Curve
Wired White v2 Estimate sailboat heel, a righting moment curve and apparent-wind reefing triggers. Compare GM, model AVS and the capsize screen with an animated hull.
Electric Boat Range Calculator: Speed, Battery and Solar
Wired White v2 Estimate electric boat range versus speed, size the battery and compare solar assistance. Includes displacement and planing models, a published test curve and map rings.
Anchor Chain Length & Scope Calculator: Catenary and Gust Loads
Wired White v2 Calculate anchor rode catenary, scope, seabed contact, anchor angle and gust loads. Compare chain, nylon and snubbers, with an animated lift-off view and swing circle.
Boat Speed, Prop Pitch, Horsepower and Fuel Cost Calculator
Wired White v2 Estimate hull speed, shaft horsepower, propeller slip and pitch, then calculate boat fuel burn and trip cost. Compare displacement, transition and planing methods.
