Thanks guys
i have moved the house/bridge 5 studs backwards, to get a better balanced place for the center of gravity. and i have began with the rear deck and making the hull longer with panels

I really like this approach on implementing such a innovative technique in a Lego model. You even manage to put you're technical builds into great looking hulls :wink:

thanks guys, the optical things are sometimes very hard for me, so your praise is good to hear.

the newest progress is a big part of the afterdeck and the winch (not working)

Nice but I can't say I'm 100 percent on the handrail and the deck house, the rail looks a little unprototypical and the house could do with a few portholes, but that's just my opinion and aesthetics... The bridge is nice and I like the extension to the hull, there are a few catamaran hulled tugs about if you google them, although most seem to be American river tugs rather than port or ocean going examples...

Edit- oh yeah how many grey panels have you got! Are there any left at Lego direct!  :grin:

i was not sure if the propellers working with all the weight, so i made a little testrun before i finish it. in this situation i made a little vid. the steering is slow and very complex to understand, but i think with the fact that is only one M motor is used for propulsion, i can be satisfied.

i hope you like it

looking good efferman!

maybe the steering would be easier if the boat had fins on the underside of the hull. But that would be difficult to do as your hulls are one piece.

But the rear part has panels that are not part of the hull, maybe extend those a bit lower into the water?

it is not the problem to drive straight forward, but rather to coordinate the two propellers. a schottel drive has a good to see push direction

a voight schneider is abit more cryptic to see, where the water will be pushed

so it is a long learning and adjustment process, till i get a smooth driving experience

I'm liking the improved house with windows, having watched the video I was going to say what thelonious mentioned regarding adding some sort of keel to the hull to aid control, if you look at the example in the video in your first post it has a large keel/fixed rudder at the rear....

does the two hulls not corrupt the waterflow
if the propeller is in between, in instead of under it

the mechanism for the pitch is between, and most of the blades is under the bottom line of the hulls. i think i will experiment with longer and other types of blades to get a better performance

in this way you lose a lot of thrust of the blades because the water reflects against the hulls
move it completly down to under the hull.
you should als consider to close the underside whith plates

The double hull is  agreat idea! Also the way it ended up it functional, realsitic and just great! One of my fave models!

ok, i have added a very big and massive blade, longer propellers and a secure plate to prevent collissions with the propellers
