As Craig says, the pontoons are relatively new - about 12 months or so.
They are at the far end of the bay, and McGochans pub is just a hop away.
There is a courtesy box at the gate for visiting boats ( proceeds go to the harbour authority) and facilities are excellent.
Do not use the seaward T end of the pontoons as this is used by local commercial boats but any of the clear finger berths should be fine. Try and avoid the ones close to the shoreline as water gets very lean at low water.
Enjoy your visit - and if you can drag youself past ( via ??
) McGochans, who do decent food, the Mishnish at the far end of the main street is always worth a call.
