Using the B7R App for Pre-Trip Navigation

Most ruined trips are decided at the dock, not at sea. A ten-minute routine the night before, worked in the right order — tide, sea state, route, log, SOS — keeps the big decisions out of the moment when the wind picks up and everyone is waiting on you. Here is the flow as it actually happens.

The night before: start with the tide

Tide decides when you can get in and, more importantly, when you can get out. B7R gives tide times for Shuwaikh and Shuaiba ports, and the two do not agree. Pick the one closest to your ground: Shuwaikh for Kuwait Bay and the harbour area, Shuaiba for the southern flats toward Khiran.

Write down three times: high water, low water, and your planned return. The rule that saves props and nerves is simple — plan to be back at least two hours before low water, so you are not running home on a falling tide with a loaded boat.

Sea state: the call you cannot postpone

Wind matters more than wave height on this coast. A short, steep chop driven by a strong northerly is harder on a small boat than a longer swell, and it builds in hours rather than days. If the forecast makes you uneasy, postponing is a good decision, not a lost day.

• Read wind direction and speed, not just wave height.
• Check the return leg: will you be punching straight into it?
• Set a turnaround point in advance. Reach it with the weather worsening, you go home. No debate.

Plan the route with the navigation tools

Lay the line out before you use it: launch point, first fishing spot, backup spot, return point. Scan the line for shallows and reef, and route around them instead of through them. Enter the points on the phone and on a dedicated GPS if you have one, because no single device should be your only copy.

A written backup spot is what stops a random decision at sea when the first mark is empty or the wind swings.

Morning of: recheck, log, and keep SOS ready

Recheck the numbers before you cast off, since wind can shift overnight. Then start the catch log: date, launch time, depth, bait, and a line of notes. Months later that log is the only honest record you have, and it is how you tell a good trip from a lucky one. Put the SOS button where your thumb finds it without looking, and show everyone aboard where it is before you leave the dock.

What no app does for you: a VHF radio on and monitoring channel 16, a life jacket for every person aboard that actually fits, and someone ashore who knows your route and your return time. Phones die, lose signal, and go over the side. Those three things stay your job as skipper.
