Never be caught with too much sail up.
Reef Now! is a safety alert for sailors. It watches the squalls, gusts and fronts heading for your position and your course, and warns you in time to reef — while the deck is still an easy place to work.

Reefing late is not a style choice. It is what breaks boats and people.
42% of charter deposit deductions trace back to torn cloth, blown seams and jammed in-mast furlers — nearly all of it done while reefing under peak load.
Operator inexperience is the #2 cause of recreational sailing accidents in US Coast Guard figures, and it shows up mostly as heavy-weather prep left too late.
One in three deck injuries — boom strikes, winch bites, tether slips — happens during a rushed sail reduction after the front has already arrived.
01
It knows where you are
Your phone's position and course over ground are matched to the marine forecast for that exact patch of water — not the harbour you left, not the nearest airport.
02
It reads the wind on your heading
Twenty knots on a broad reach is a lovely afternoon. The same twenty on the nose is a reef. Reef Now! works in apparent wind for the course you are steering, gusts included.
03
It pushes both ways
Reef in before the front, shake it out when the breeze softens. Both are a notification with a number attached, so nobody has to win an argument in the cockpit.
04
It learns your boat
Tell it the boat and how you like to sail her — cruising with guests, or pressing on. Every reef you take, early or late, moves the threshold closer to your own judgement.
An alert you can act on in thirty seconds.
An alert you can read with one hand on the wheel and salt on the screen: what is coming, when it hits, and how much sail to carry into it.
Take the first reef in 12 minutes.
Gusts 26 kn from 240° on your heading of 285°. Building for the next two hours.
Shake it out — down to 14 kn steady.
Nothing to do. Wind holding under 12 kn until dark.
Every passage keeps its own weather.
Track, wind, sail plan and each reef, written down while you sailed it. Export the season, settle a bet, or find out what you were actually carrying the day it went sideways.
| Passage | Distance | Wind | Reefs | Notes |
|---|---|---|---|---|
| Split → Hvar | 24.6 nm | SW 12–26 kn | 1, then 2 | Front arrived 20 min early |
| Hvar → Vis | 18.2 nm | NW 8–14 kn | none | Full main all day |
| Vis → Korčula | 31.4 nm | E 18–32 kn | 2 from noon | Night arrival, moon up |
The first reef is always twenty minutes late. Now it isn't.
