We’ve been using Starlink RV with the rectangular dishy since early November in Brisbane, along the NSW and VIC coasts. Great upgrade over relying on Telstra towers for mobile coverage. We’ve used it up to 20 miles offshore and boat speeds up to 20 knots – no problems at all. One thing we’ve noticed that if it is turned on while the boat is moving that it never stops “Searching”. If that happens we simply slow down to below 1.5 knots boat speed for a minute or so, then once it is online we can speed back up again.
It does have odd short interruptions due to network issues and sometimes obstructions (such as the mast if the boat rotates at anchor). It also has difficulty if the view to the south is blocked by tall mountains.
We are paying AUD174 per month. Not super cheap, but much more effective than mobile and cheaper (and faster) than other satellite services. It is awesome and certainly a game changer for coastal connectivity. We are keeping our Iridium Go for passages.
