I have this https://www.amazon.com/FELL-Marine-Wireless-Switch-Basepack/... on my 23 foot day cruiser and I'm very happy with it.
Sometimes cuts when I'm on the dock untying etc but could probably be improved by adjusting the antennae orientation.

When untying it only cuts once in a while when doing the bow lines and I'm still attached at the stern, so no risk there.
When preparing to dock it's only if I need to find and prepare extra rope from some of the most aft compartments, which I do well ahead of when I need them and not during "critical phases of operation".
If I expect to be running around a lot during docking I take the FOB off and place it on the dashboard. I don't leave the helm unless the gear is in neutral, and if I fall in the water I'm usually within 20 meters of land which I'm fairly certain I'd be able to reach :)
