Further to my latest thread re the saga of our new Oil Spill Response Vessel (here at http://www.ybw.com/forums/showthread.php?t=240767 ) where I threw in a mystery boat question, here is another photo of it's bow from a bit closer.
We have established that it is European, but not an Astondoa or a Feretti....... I'm sure that you will get it now.
And changing tack, I saw a link to this Youtube video http://www.youtube.com/watch?v=bcxZ-re8EDI on the Facebook page of 'Marine Engineering & Naval Architecture' at http://www.facebook.com/#!/pages/Al...l-architecture/104582308992?ajaxpipe=1&__a=19 (but I think you have to be logged into Facebook to see their site).
I am surprised in a way that Voith cycloidal propulsion systems do not appear to have been used before for oil rig supply vessels (they are very popular with tugs, and are used, I think, by the Lymington ferries), but perhaps the main factor involved is the extra cost involved, when compared to 'conventional' propellers and shafts.
Changing tack again, I went to have a look at a Bayliner motor yacht here recently - it had recently been shipped down here from Miami, and is a sister ship to the one shown in this Yachtworld link - http://www.yachtworld.com/core/listing/boatMergedDetails.jsp?boat_id=2131206& except that the boat here has twin diesels rather than petrol engines.
And the boat here also has a diesel generator - underneath the cockpit sole.
And the cockpit looks (or used to rather) just like the one shown in the link.
The aft hatch is for access to the steering gear - here is another photo below :
You can just see the generator lurking....... the owner had recently cut out the cockpit sole above the generator in order to obtain reasonable access to it, as shown below :
The generator is obviously much younger than the boat, hence I am wondering how they got it in to that space when it was installed...... as the cockpit sole did not appear to have been tampered with previously.
They were going to bond the section of sole back down again, but I suggested it might be better to make this section a removable hatch, in the same fashion as the SG compartment hatch, and extend the drainage channels forward.
The two main engines are also classic examples of how to squeeze something into a very tight space - and let somebody else worry about maintenance access afterwards......
Copied below is a view on the starboard main engine looking forward.
While here is a view on the forward end of this engine, from inside the saloon -
And the access to the starboard engine is much better than for the port engine! I think the only way to get to the forward end of the port engine is to crawl through a small hole in the midships cabin bulkhead.
