Plas Heli has received Plans for the replacement platform and stairway.
This south facing elevated platform will increase the balcony space on the first floor for social functions, and will provide our customers with great views over the sea, compound and the Hafan Marina.
The balcony will also provide useful covered space on the ground floor for use during large events and we have ensured that we have water and power provided to this new area.

Maximum speed in the channel is 4 Knots.
Harbour Master VHF CH 12

Check the tides to make sure you have sufficient water under the boat for a safe passage up the channel. There is a tide board on the perch on the right hand side of the channel.
We suggest that you do not attempt to enter when the depth on the board is equal to or less than the draught of your vessel plus 0.5m on a rising tide. You should allow a greater margin on a falling tide. Follow the route outlined below.
Proceed to the chanel entrance from the direction of the Fairway Buoy. Do not cut the corner at the south side of the entrance.
As a general rule:
Red on the chartlet-
Blue on the chartlet-
After the last green perch cross to the south side of the channel and follow the trots, leaving the green chanel marker buoys well to your right. The deepest water is where the boats are moored.
Then continue up the chanel to the Plas Heli pontoons which are to the north of the Hafan Marina.
If you are instructed to berth on the northen side of the Plas Heli pontoons please do not give a wide berth - stay close to the pontoons. The depth decreases rapidly to the noth of the Plas Heli basin.
