She's looking really nice, BT! 8)

However, although it may just be the angle, I'm a bit concerned about the (rear) tubes launching into the front foils. :icon_crap:

 Yeah, I see that too - but that's just a training challenge ;)

 Good looking work - I will be studying the Molins mount for reference.

Me too, it was part of the giving up on the whole wringing of hands thing and handing over to the suspension of belief and magic of whiffery.
The total number of actual MTB on Hydrofoils appears to be close to zero, more than likely for exactly this reason. Once embed in the base a lot of the issues we all see will hopefully be out of sight.

Craig if you want actual drawings of the naval Molins mount, I can provide them, I have the most excellent Lambert "Anatomy of the ship"  book on the Fairmile MTB/MGB family which has engineering drawings of all weapons used on this class of vessel. My version is a rough rudimentary approximation of those.

Another thought is, I wonder if you might have a risk of running into your torpedo before it got up to
speed?
 :-\

Perhaps the technique would be to slow the boat and drop back down to hull borne, but still planing,
before launching the torpedoes, just long enough to launch and then turn away accelerating back to
being foil borne. Basically come in fast, suddenly slow, then turn and speed away.

I have decided that in this build universe, the magic of whiffery has decreed that the boffins have come up with a way to extend the distance a torpedo will launch so it is outside foil zone.
Also the torpedoes may have become secondary armament due to the heavier 6 pounder mount due to your valid point about lack of viable targets.

Buildwise, on a bit of a roll.

Moving onto the base. It is a foam base, with some sculptamould base texture. This was allowed to dry then a couple of sheets of blue crepe paper was laid over the entire thing and then wetted down with diluted white glue, which added further "wavy" texture and a more merged surface.


After that had dried, the next step was a quick coat of paint to check it out and then starting to pack in more crepe paper around the hydrofoil business, only with water at this stage, because my logic says, I should be able to still remove it. We shall see if logic wins over reality

Indeed - I will have to try that for the base for the Revenant. Really liking the colors overall.

You probably have this covered so please excuse a dumb question:  If the boat is on it's foil (hull out of the water), shouldn't there be a wake coming off the foil legs at the point of exit of the water ?

Work in progress... last couple were just progress shots. I am out of Gel medium for the water, so when I get that in the next day or so, we can go for the next stage, which will indeed include wake... lots of wake.

Well that's about it. Call it done for what it is.
I got to thinking about pulling off both torpedo tubes and creating a Destroyer type rotating mount, like this (thanks for the pic shapeways).. but only a triple mount, trash the Oerlikon mount


Luckily, I then decided. Nup, for the intended purposes, it will do. Not quite sure about the dumbflow exhaust outlet attempt. With them on

With this beam side off. Leaning toward off as getting this water/exhaust mix to look any good appears to be rather a challenge


Couple more beauty shots



thanks for dropping by and the excellent discussion on this topic.

I'd lose the side fountains, they just don't look right. :-\

Plus, with the hydrofoil, where are you getting that much water to pump out anyway? ???

The boat looks fast and menacing and the water surface looks realistic, but I agree with Guy - the water fountains don't make sense and detract from the sense of speed.

I do like your on-foil display and that 2-pr is quite fetching. 

The one image showing the stream of fluid being ejected from the engine exhaust seems a bit excessive and that also brings up the question of where is the water intake for the exhaust located when the hull is foil borne?  Maybe replace the fluid stream with a puff of steam/exhaust by using something with a very fine fibre such as a piece of cotton ball for example. 

Other than that, great work!

Thanks Team, I totally agree the exhaust stream does not work. It will be fully removed. Not that this model will be seen anywhere else much. Might replace some pix though with them gone

Plus, with the hydrofoil, where are you getting that much water to pump out anyway? ???

I figured that the intake pipe could quite easily be within the Hydrofoil supports, not that different to the skeg that was the water inlet on my last ski boat.

All in all glad you like how it came out. Except the naff exhaust attempt  ;)

Vosper built an experimental MTB, the Bloodhound, that had a trainable torpedo tube, the
torpedoman sat astride the tube. It worked but it was heavy so the concept was never
carried forward on any production boat. The boat was later used in torpedo development
work.
