Say you and two friends are going from Haro Strait to Rosario Strait, then anchoring for the night. Here's how it might go.
The night before: check the conditions
Turn on Wind and Current in Layers, and tap an hour to see tomorrow morning. Tap the passes you're thinking about for their numbers.
Plan the route
Tap Draw a route, then your start and your destination. If it goes north of Orcas Island and you'd rather go south, drag a point there and tap Recalculate. Check it against your chart, then save it.
Set your leaving time and see when you'll arrive. More about routes.
Get everyone on the same plan
Start a fleet and send your friends the invite. Then open your route and tap Send to fleet, so they can save it too. More about fleets.
Cast off
Tap Start on your route and Record trip to keep your track. Open Heads-up for big numbers at the helm.
Under way
The route turns green as you go. Your friends' boats show on your map, and a tap on one shows its numbers. Send a quick "All OK?" or "Slowing down" when you need to. Keep your eyes on the water, and your VHF on.
Choose an anchorage
Check Marks for what other boaters found. Tap the spot you like, then Hour by hour, then Anchor here. Enter your sounding and how long you're staying, and pick a scope.
Send "Anchoring here" to the fleet. More about anchor math.
Share what you found
Tap Stop trip, then Drop a mark and tell the next boater about the holding, the swell or the view. It's public, so think about what it gives away. Your trip stays private under You, then Trips. More about marks.
