Fifty Feet of Grey (steel)

Sod the maintenance go for the wood cappings.
LOL, if you really don't mind wood maintenance, I've got some 32 tons of timber where you're always welcome to practice some sanding, varnishing, painting, etc... :D

No thanks (it's always easier to be an "armchair boat builder" when someone else has to do all the hard work)!

Seriously, to varnish just a guard rail on a 40 footer shouldn't take more than a day should it? Is it possible to design long interrupted sections for fast sanding and varnishing with no fiddly bits? Something like this?

Probably spend more time masking off "properly" than varnishing!
 
An update....

The yard has dried out after having an excess of the irish sea in it....

We have the jig made, and started layout of the steel work. The first formers are in situ.
Pics to follow.
Had a chat with sleipner at LIBS. They are looking at the stability calcs and drawings, and sending me details of the shear forces for the stiffener plates to be calculated. Also will give me correct location for mounting, which is in the engine room. So that will make life easy.
Mike was trying to talk me in to dc thrusters, the yard still prefer proportional hydraulic?? Decisions decisions...
They also recommended a larger thruster tube for the bow.
Will get all the info for both systems, and feedback to Pilkington for pto calcs and pump sizes for hydraulics. Will price up, size up and work out the weights of both systems. Cummins have also introduced a joystick control for inboards and shafts, how effective it is im not sure, and wether its required, or if we stay traditional....

I also looked at the fair/prin/seekers at Libs for ideas. I was quite surprised by the lack of traditional analogue gauges for engines. All seems to have gone canbus. Personally i like gauges.
 
I too like a quick glance at analogue gauges, with needles pointing in the right direction. I'm not sure I want to demand info, every time I want it, then decipher the digi info.
 
I have a electric bow thruster and it does it's job fairly well, I'd much rather have a larger hydraulic one, size is good and hydraulics are so much more controllable, and quiet.
 
I take it a joystick system on a twin shaft boat links in with the bow (and stern if fitted) truster? Interesting. I'd say cost could well determine the outcome on that decision! Certainly I wouldn't be interested in paying big money for such a system especially if you're already experienced!

Lot to be said for an "end of an era" boat with regards to not having a joystick system, if that is how the industry is going..
 
Rob, I'm sure you can get a mix? Use the big Garmin screen for the detailed info, and some boggo analogues for the everyday condition.

My thoughts exactly.
I have a set of gauges on there way, so i can mock up panels. On loan.
The garmin screens i wanted to fit in the roof void, and use a joystick for them.


The cummins book says no stern thruster required for there system. I dont know if it ties in with the rudders, dont have all the details yet, just the promo brochure.
More inclined to go with traditional setup i think.

The biggest consumer of hydraulic power is thrusters, not stabs. Stabiliser requirement from hydraulics is pretty much bugger all...

The option for integrating the engine controls with the thruster gives you another option of a remote control system, which you could use from the cockpit to berth, rather than from the helm. Not so hard to do if you can get access to the engine controller software, and someone can write you a prog over the top.

Yes and no, Rob.
Thrusters indeed demand a high flow, which ain't required by stabs while cruising (though stabs do require a rather high pressure, anyway).
But at rest, also the stabs flow ain't trivial.
Besides, if you go all the way hyd, also winches draw quite some power.

Fwiw, I fully agree that joystick is pointless on a shafts boat.
It's indeed useful - almost necessary, I'd dare saying - with pods, because handling manually (and separately) the thrust direction of the two things would be a nightmare. But with shafts+thruster(s), it's all very intuitive, and it's just a matter of getting used to the hull-specific lag/reaction.
 
Hi Robin
Ill follow up this week.
I am off to the yard on tuesday, but they are making steady progress. bearing in mind they were flooded out, and a dutch barge they had built nearly floated off prematurely.... Its not kitted out, just an empty hull.... :)
