It's true you do need a launch permit. Launch Permits — Registration Forms — Waters of Principle Use
Owners of unpowered boats (canoes, kayaks, rowboats, etc.) can launch their boats at Commission lakes and access areas or Pennsylvania state parks if their boats display a Commission launch use permit, boat registration, or PA State Parks launch permit or mooring permit. Pennsylvania State Parks recognizes Commission boat registrations and launch permits. The Commission does NOT recognize launch permits from other states. A Commission launch permit application is located on the inside page of the Boating Handbook wrapper or can be purchased online at the Commission's web site.
WATERS OF PRINCIPAL USE
Vessels must be registered in the state in which the boat is primarily used. If the boat is waterborne (including time at a marina slip or mooring) on Pennsylvania waters more than on waters of another state, it must be registered in Pennsylvania regardless of where the owner lives. Reciprocal privileges are granted to boats with valid registration in other states for up to 60 days.
Note: A Pennsylvania Use Tax is charged for any boat owned by a Pennsylvania resident if that boat is at any time brought into the Commonwealth regardless of where it is registered. There is an exception for casual sales of unpowered boats. Credit is given for tax paid to other states.
Hope this helps.
