Lies, damn lies and official marina dredged depths.

The current story is that the cutter suction dredger being built for Premier in Italy is being delayed (and when finished, it'll not instantly teleport to the south coast either)...

Are Brighton getting first dibs on this or do they have to wait their turn along with all the other Premier marinas ?

Good luck to any deep keel yachts coming in to Sparkes on a low spring. Upside is that "Hayling Rescue" is rarely far away. In mitigation, the dredger is active, and should make a difference, but it's still the case that there's a fair sized extra sandbank or two that wasn't there last season.

One word of caution here -- most people are fairly sanguine about dipping their keel in the mud and rightly so. A bigger danger emerges when its time for a spade rudder to bottom out. My depth is a tad more than yours (2.4m and 1.9m rudder), but I'd be seriously worried about pushing the rudder into one of those metal fences Yngmar refers to in post #28.

The trouble is whilst most rudder stocks will have hefty design tolerance when stressed in the lateral plane, vertical plane tolerances are another matter. So I'd prob take a good look at how vertical loads will be dissipated through your hull before your rudder gets anywhere near the bottom.

Incidentally I've just had new top and bottom bearings from Jefa -- I have also taken up home brewing to save the remaining beer tokens :ambivalence:

Sensible advice. Hopefully, my 60cm is a worst case for two reasons:

Firstly, he said that the depth along the visitor berth varied from 2.0m to 0.2m below CD, and I'll take care not to moor up on the shallowest part.

Secondly, I was also informed that they are dredging again next month. Fingers crossed they might do the bit of the visitor pontoons at CD - 0.2m. (Ok, so this one might be a bit optimistic).

Oh, and I just thought of a third. The weather is usually terrible whenever I go to Brighton, so no doubt the low pressure and southerly gales will give me a bit of extra depth. ;)

Well some have all the luck; I usually end up rolling around on a dead run all the way to Brighton and then a blooming beat all the way back ....which in turn means that if I'm trying to carry the tide with me making the sea as bumpy as you like :rolleyes:
 
Gosport marina dredged depths.

Well a large dredger has turned up in Premier Marina Gosport at lunch time. He drove all the way round to the lifting area and started work with a large grab lifting out the mud. Hurrah!

Pete, I thought that the spoil barge Split Two had been in and out of Gosport for the last couple of weeks or was it up at Royal Clarence?
 
Re: Gosport marina dredged depths.

If its the big red and black one it may have been working there for a couple of weeks in Premier. Us office folk rarely see the harbour during a working day but a chance of lunch in the Boat House was a nice change. I did wonder were he was going in the barge, bloody great big thing and going at a fair rate of knots, must have been on piece work.

RN must be busy, all the grey funnel line boats have disappeared apart from the T45 in the basin they keep nicking bits off to keep the others going :-(
 
Re: Gosport marina dredged depths.

Brighton is also finally getting some dredging, currently at the entrance and the visitor berths. The backhoe dredger however can't do the rest of the berths and the cutter suction dredger which is supposed to do the job is still indefinitely delayed.

Meanwhile I'm stuck up to my saildrive's raw water intakes in the mud at low water springs - and I'm on one of the berths marked "green" on the recent survey.

That I can understand as they already have your money and are concentrating on areas that will earn more revenue.
 
Re: Gosport marina dredged depths.

How much would it cost to setup a dredging business as there seems to be an imbalance in demand and supply?
 
Re: Gosport marina dredged depths.

A few years ago Calais empty the marina of all boats and pontoons in the winter months and dredged to around 4m. They paid for the boats to be lifted out or for alternative moorings up the coast. The marina is run by the port.

Ok I will scrap that business idea. .

IT would appear the senior service plan a huge dredging operation for Portsmouth harbour thanks to someone ordering a couple of ships on steriods. Hopefully all the mud in the side bits will slide down into the hole for amny years to come.
