Sail Simulator
Harbor estimate: NWS-preferred wind (GFS/ECMWF/ICON fallback) is reduced for Manhattan shadow and NOAA Entrance current is scaled locally. T/J marks a computed maneuver. Immediate turn at Robbins limit, explicit final approach to Pier 25, 15-minute reserve. Planning only.

Advisories
NWS forecaster-written outlook for the whole NY Harbor zone (ANZ338) — the product behind VHF broadcasts and Small Craft Advisories. Coarser than the hourly widgets but adds wave heights; use it to pick a sail day, the hourly cards to tune the window.
