coming up later ...... difficult to get the shots I want as it is quite difficult to make it clear ..... the first photos don't quite show it properly.
Very strange underwater profile.

Been having a look at the tugs in the drydock ....... the little one is tiny and I have never seen anything quite like it before, Its a tiny square pusher tug, a blunt twin engined mini cat ...... I said earlier about the lack of "boaty shaping" of narrowboats but this would make a tin bath look shapely. It is designed just to push a row of pans around. I don't know what the engine power is but I would think it is quite high judging by the size of the props SAM_1244 by mudlarker2, on Flickr SAM_1245 by mudlarker2, on Flickr SAM_1253 by mudlarker2, on Flickr That must be a very capable small pusher tug John, I've seen quite a few tiny little pusher tugs in the US, most had screaming GM 2 strokes permanently running full throttle. They built a small pusher tugs in the Netherlands that can be transported world wide in a container : www.nauticexpo.com/prod/containertug-bv/product-57045-419763.htmlPeter.

I have been trying to take some photos of the Lashette that show her unusual underwater profile. It is very difficult to do. She is powered by two directional thrusters mounted just forward of amidships and because of their height she has 3 legs forward with what almost looks like a hydrofoil section between them and a huge fin aft acting as the 4th leg. She sits on these on the drydock bottom, no blocks being used. SAM_1243 by mudlarker2, on Flickr In this photo taken from dead ahead you can see the forward legs (the centre one is in deep shadow) you can also see the strange asymmetric "hydrofoil shapes" the one on the starboard side goes from the bottom of the outboard leg to the bottom of the centre leg but the portside one goes from the bottom of the outside leg to near the top of the centre leg. Nobody has been able to tell me why !!! SAM_1248 by mudlarker2, on Flickr one of the thrusters, you can also see the aft leg/fin in the background. SAM_1247 by mudlarker2, on Flickr in this one you can see the strange "hydrofoil" shapes more clearly SAM_1275 by mudlarker2, on Flickr propellers removed to refurbish seals and bearings SAM_1278 by mudlarker2, on Flickr SAM_1269 by mudlarker2, on Flickr SAM_1270 by mudlarker2, on Flickr welders at work (one inside the bow cutting out damaged plate and frames)

I can almost see you laying flat on the floor of that drydock to take all these very good photos John, thanks they're really interesting. No idea why those bars are hydrofoil shaped, as it's certainly not a high speed machine, maybe it was only done to make people wonder why it was done, just for the fun of it. These steering props look like Schottel drive props, there are 2 other well known makers of RP's in the Netherlands HRP and VETH, they are all slightly different but do the same thing, and with-or without a nozzle around them. Schottel HRP VETH Peter.

as I mentioned in the "what a cracker I want one" thread, I had a run down the river Hull yesterday in a fast workboat (Nelson 34) Here are a few shots from the trip Leaving the yard SAM_1430 by mudlarker2, on Flickr under the first bridge (permanently raised ..... is an interesting historical bridge, it's hydraulics were supplied by a high pressure municipal water supply (the first such in the country) similar systems were installed in Grimsby and Goole where the incredible Victorian water towers can still be seen.
