Finally an update again, though not really a big one...
Tweety has been aboard again!!
Up close and personal.
Nothing much has changed other then ideas I had about how to proceed with this build.
The wooden hull will actually be the hull rather then just a plug, this is because the major reasons for making a GRP hull have fallen apart: I checked the weight calculation and found a few items that had weights estimated kilo's heavier then they'll ever be...
Beside that, as can be seen in this post, the wooden hull still offers plenty of space as it's designed now for all the functions and it saves me weight in ballast.
Then there is the ballast item: I had been thinking about using ballast tanks but recently I found out that there is no room for big enough ballast tanks in the stern due to the moonpool which has become more important then it ever was.
Therefore I decided that steel ballast isn't quite a bad thing to have so in this photo you can see almost 5 kilos of steel ballast packed together in 3 packs.
There will be a frame to keep it from moving about.
Then there are 3 pumps, 2 for cooling water and 1 to flush the anchors.
There are also 2 Speed 500-size engines to power the bowthrusters and there is an Arduino Mega without it's to be designed PCB.
This is midships with 2 batteries which will be turned around so the tops will end up in the middle with the batteries placed as far away from each other as possible and the batteries will also be placed in a frame to keep it from moving about.
The central computer (without it's still to be designed PCB) is placed on deck here because there is no room to put it in between the frames at the top.
Here is the stern with 2 Speed 500 E engines and 2 stepper motors and 1 cooling water pump, there is also an Arduino Mega for which I will also design a PCB.
There is also a little over 5kilos of ballast packed together like in the bow.
