GPS numbers for a route into Bembridge Harbour
9 years 8 months ago #1
GPS route into Bembridge Harbour, based on WGS84 co-ordinates.
Supplied without guarantee – before placing any reliance on these numbers, they should be verified & amended, if necessary, to reflect actual observations taken whilst following the route in good visibility. GPS positions can vary slightly from installation to installation, depending on a number of variables.
Particular care is needed in the narrow entrance to the actual harbour as the accuracy of GPS is not good enough, on its own, to ensure safe navigation in this section on all but high tide & good visibility.
The position of deepest water can vary from season to season & a few yards can make the difference between grounding & safe navigation. That said, grounding on a rising tide is not a major disaster given that there are no rocks in the immediate vicinity of the shallow sections of the channel.
Safe navigation is not possible for all but very small boats up to two hours either side of low water.
This route takes one outside the fort & it is recommended that this be followed two & up to three hours either side of low water. For less than three hours either side of high water, it is generally safe to follow a line from the outer corner of the dogleg to a point further along the route somewhere off the lifeboat station.
Care should be exercised between the ledge buoy & the entrance channel to avoid the numerous pot markers & moorings.
Some sections of the route inshore of the dogleg & also a section half way along the route between the dogleg & the radar pole are more shallow than the remainder of the route.
This route follows the deepest channel & may involve navigation on the “wrong” side of the marked channel on a couple of occasions.
Normal navigation rules should be observed when in the proximity of other vessels including the local speed limit.
When coming into the harbour the channel does a sharp right turn just past the wooden groin.
Suggest that the following numbers be loaded into a GPS as a “route”.
“CH” designations do not relate to any buoy numbers (some are actually points between buoys) & may be renamed to suit individual needs.
The advised compass directions (in degrees) relate to coming into the harbour.
Leaving the harbour will require the reciprocal course to be steered.
