Maritime Toolkit

Scope from the roller not the waterline. Reef for the gust not the average. Ten tools that answer a question and get out of the way, all offline.

Maritime Toolkit is the working answers a skipper needs on deck, in one app that never asks for a signal.

TEN TOOLS, ONE INDEX Search for what you need or browse by what you are doing — anchoring, sail and weather, lines and warps, navigation, safety. Every tool opens to a single clear screen and gives one answer.

ANCHORING Scope worked from the bow roller and the depth at high water, not the waterline and the depth you see now. Then the swing circle that rode actually draws, so you know what you need between you and the boat that anchored after you.

SAIL AND WEATHER When to reef, weighted toward the gust rather than the average — because a ten-knot spread between mean and gust is exactly where a simple average misleads. Plus the signs that work when you have no instruments at all.

LINES, NAVIGATION, SAFETY Which rope for which job and why. Dock line diameter and the four lengths worth carrying. Compass to true and back. Distance off by vertical sextant angle. Fuel range on thirds. The man overboard sequence in order. What each sound signal means, and the one blast that means two different things.

WORKS OFFLINE No account, no sign-in, no data connection — because the cockpit is exactly where the signal goes.

Every figure is a starting point for a competent skipper, not an instruction. The official publications — the collision regulations, your almanac, your engine manual — always take priority.
