Continuous Cruising - update

IDAMAY said:
I spent quite a lot of time on the flybridge during the trip from Padstow to Cardiff and found the constant background hum of the exhaust very reassuring. Certainly there was more noise than with a typical wet exhaust set up but it didn't seem to me to be too intrusive. I know that Mark (the other crew member) felt the same.

100% agree Richard. I was concerned at first with the thought of the exhaust right behind us on the fly. However I felt the sound was reassuring, soft and never ever missed a beat during our transit. Im still looking for one :encouragement:

Not sure whether the wet exhaust boats have a similar closed keel cooling system. You would think not at least with twin engined models and maybe thats why the twin engined boats can only have wet exhausts ie because the closed keel cooling system does not have enough cooling capacity for a twin engine set up

Possibly, but not necessarily - hence my curiosity.
I've seen a few steel trawlers where raw water was only meant for the wet exhaust, with engine cooling handled by the keel closed circuit, avoiding salt water anywhere around the engine.
And I see no reason why Nordhavn couldn't do the other way round (heat exchangers for engines cooling, but still with dry exhausts)...
...though maybe the train of thoughts is that once you accept to depend on raw water flow for engine cooling, you can as well have a wet exhaust - just guessing, anyway!
 
Excellent video and great to see the year, in 15 mins, of cruising. I almost think we should be made to post a 15min recount of our years boating on this forum, would make for interesting watching!

Seems like the Nordhavn dry exhaust system relies entirely on keel cooling via an external heat exchanger so no need to bring sea water into the boat at all http://www.nordhavn.com/resources/tech/exhaust.php

Having said that this article also states that wet exhausts may be necessary for twin engine set ups. Maybe that is because a dry exhaust set up takes up accommodation space and a twin dry exhaust system would take up an unacceptable amount of space?
 
Enjoyed the video, you've done more in one season than many do in years! Good to meet you both in Dartmouth on Eos, we also didn't make Scilly this year, the first failure for about 7 years, the weather never really settled down; you'll have to schedule a visit another year!

No need to bring seawater on to the boat:confused:.... except for the generator, wing engine, watermaker, heads raw water flush (we use fresh water but the seacock and strainer are still there), anchor chainwash...

That's a comfort, we thought it might have been just our lack of nerve that stopped us getting to Scilly. We learned from our failure, also we learned from the day we spent bashing through head seas to get to Portland to make an appointment to take friends on a short cruise.... they chickened out. From now on NO PLANS. I don't mean no passage planning, I just mean take each passage as it comes and don't have an itinerary for the season.

Thanks for welcoming us on Eos - that was great. We had 6 meetings with forumites during the summer and hope for many more.

Hi Twohooter, when you refuelled at Camber Quay, Portsmouth who provided the fuel and how much was it? Always looking for the best fuel price :)

Fuel supplier:
Certas Energy UK Limited
Oil Teminal
Belvidere Road
Northam
Southampton
SO14 5AF
Phone: 02380 216166
Joe.Spragg@certasenergy.co.uk

We loaded 2,000 litres and they were happy to supply that quantity, I don't know what the minimum order is. Make sure you ask for BS ISO 8217 (2010) (Trade name: DMA) and state the intended purpose is Marine Fuel. This can theoretically have up to 0.1% FAME but in practice is likely to be FAME-free. Don't accept BS2869 (aka Class D Gas Oil), this can have up to 7% FAME. The fuel is pumped direct from Fawley to the Hythe rack and loaded there by Certas' own tankers so it should be as fresh as a daisy. The complete opposite of loading from someone who has dirty tanks and low throughput of fuel. Our supply had been in the boat's tanks for 6 months when I did the annual change of the Racor filters and we haven't seen a drop of water all year in the filter bowls or the supply tank sump so I reckon there's no water in it. The other data in case you want it is:
Maximum sulphur content: 1%
Minimum density: 890.0 kg/m3
Minimum flash point: 60°C

Certas will give you the current price, not much point in telling you what we paid because it was too long ago. Make sure you get a copy of the ticket AND a copy of the 60/40 declaration for you to sign and keep a copy of. If you have any problems with this side of things the contact is denise.stevens@certasenergy.co.uk

Berthing at Camber is arranged with KB Boat Park
First Floor, 96 Broad Street
Old Portsmouth
PO1 2JE
Telephone: +44 (0) 2392 833166
Yard Mobile: +44 (0) 7733 880 260
E-Mail: info@kb-boatpark.co.uk
We paid £7.95 for a short stay (12m boat).

You will need a fender board. This isn't a marina, it's a fish dock. We had to run our lines behind the timber berthing piles and they got a bit mucky. The ladders are rusty and mucky so everyone needs gloves. The tanker pump is powerful - make absolutely sure you are ready and have a firm grip on the nozzle before the driver turns his pump on, then squeeze the nozzle veeeeery carefully. Good idea to have plenty of swabs available, we didn't spill a drop but I was surprised by the flow rate, it is much faster than the typical marina or roadside filling station and it might be a good idea to have someone watching your tank vent/s during the fill, just in case.

Let us all know how you get on.
 
Re: Continuous Cruising - update (diesel supplies)

Thanks TwoHooter. Thats very detailed. My boat takes about 1200ltrs but I only run them down to half full as my average fill is about 600ltrs. I probably used about 2000ltrs last year so I am always looking for a an alternative supplier and a better price. The better the price the more I can take the boat out :)
