22 is very small. Most boats this size have very little eqip as very little is necessary to sail lakes / inshore waters. Whatever is necessary will already make the boat pretty loaded.
Yet, some boats of this size will have many toys, radar included.
In any voyage where I might run into any risk of getting
lost, I would still like to have (budget permitting) a small GPS plotter AND the paper chart.
Budget not permitting, a paper chart. In some areas a little plotter will have an edge over paper chart - e.g. in fjord type of coast with many rocks and side chanels. If the coast is miles of sandy beach, then you will be very happy with just a paper chart.
Another thing worth having is some sort of
radio to pick up the weather
forecast. The type depends on what the best source of
forecast there is in your area.
A
motor, can be
outboard, is also very nice to have.
Nav lights, if you plan to sail at night.
Windvane, if you plan to sail alone.
Just imagine the area you want to use your boat in, then if you can do without something, do without it.
Travel light.
