Funny thing is, that she would probably do 42 kts with 50,000 HP and
the next 2 knots would take 3 times as much. Such is the rule of
displacement vessels. To take that one theoretical step further, if
they wanted to go 46 knots, they's need 400,000 HP. 47kt 1 million. 50
kts a bezllion HP

I think 55 knots or so is the theoretical maximum a vessel can move through
the water, irrespective of the power pushing it.

As the speed increases, the vessel begins to outrun its bow wave. It then
has to ride over the bow wave or push through it. The faster the vessel, the
bigger the bow wave.

Sort of like the increase in mass with velocity and, as the velocity
approaches the speed of light, the mass becomes infinite. Only not exactly.

Not exactly indeed.

The maximum speed of a displacement vessel is determined by its
length. The longer, the faster.... with the same power.

Nope. not even close

Currently, unlimited power-boat races are in the 160MPH range. in years past,
they got up into the 200 MPH range, but engine/fuel restrictions have brought
the speeds down.

'Cigarette' boats can reach 80+knots in calm water.

Some torpedoes -- which travel entirely underwater -- have sustained speeds
well over 100 knots.

unlimiteds aren't displacement boats, they're hydroplanes. Cigarette
boats are also on plane at speed and therefore not displacement vessels.
My physicist buddy that does torpedo testing says max speed for a
conventional torpedo is 55 knots, but supercavitating torpedoes are
capable of much higher speeds by essentially traveling in a gas bubble
and are therefore also not technically [water] displacement devices.

I'll simply suggest that _something_ is moving the water out of the way,
be it the torpedo body or the 'gas bubble'. Else an elementary fact
of physics is being violated. *OR* somebody has managed to implement
the tunnel diode at a macro scale. grin

Your physicist buddy is playing word games. The torpedo is going so
fast that flow detaches from its surface at the transition from the nose
cone to the body. But it is most assuredly travelling in water.

In any case the British seem to be laboring under the misconception that
their Spearfish torpedo can exceed 60 knots. Perhaps he should call
them and inform them of their error.

Speaking of sail, the thing that amazes me is the speeds that are being
sustained under sail. At the rate things are going it won't be long
before United States' transatlantic record falls to a sailing
yacht--last August Banque Populaire 5 came within about 9 hours of
beating it. 32 knots under sail, all the way across. I remember when
Crossbow first managed to struggle over 30 knots on a short measured
course and now that's being bettered for thousands of miles at a

Cool. Is that thing listing from just going over a humongous swell,
or what?

Think skid (notice the bubbles off the bow). The swell is his.

Wull, ya just don't "whip a U-ey" in a boat which takes a mile and a
half to stop or turn.

Vapor condensing. I've seen some amazing pictures similar to this.

Yeah, me, too, but this was the first and best I've seen.

Yup - fluidyne water jet. I've been doing a lot of re-design and it
appears that I can boost both the efficiency and the oscillation rate to
the limits of mechanical check valves.

With a platform like the Hoby, I think I can mount a tracking solar
concentrator and have 3-4 kW of input power to work with and (perhaps)
50% of that in pump power.

My problem is that I'm not sure that'd be enough to pull a twin-hull
platform.

Heh - it just occurred to me that if I needed a horn, I could disconnect
the pump and use the engine (at say, } to warn off the jet
skiers.

I thoroughly despise jet skis..... to be more precise, I thoroughly
despise the Great Unwashed who seem to see the need to get drunk and
destroy the very expensive peace and quiet one pays for on the shores
of otherwise untainted inland lakes.

That should be about the same power output as the old Evinrude Lightwin.
Not gonna move a Hobie _fast_ but it will move it at a useful speed
assuming you don't lose much efficiency in the propulsor.

Thanks, John, that's what I needed to know. I'm not sure how well it's
going to work out, but that tells me that it's worth a try. The engine
isn't anywhere near as big a deal as the tracking system needed to keep
the collector pointed at the sun.

Propulsion will be essentially a straight path with a tee connection to
the engine between a pair of check valves. During the expansion half of
the cycle water will be discharged rearward, and during the contraction
half of the cycle water will be sucked in from the forward direction.

I don't need to go fast - I just need to come _back_.

ron @ fastlane sailing in san diego (http://www.fastlanesailing.com/) has a
hobie with a hard deck and power boat console mounted on top. they run
theirs with an outboard, but i don't know how big it is. you might contact
him for further details.

I've stashed the link for when I have an engine ready for the job. First
I need to get engine and tracking system worked out. The Hobie (spelling
corrected) will be a rental boat, so whatever I come up with will be
something I can assemble and set in place at the marina, then lift
off/disassemble when I'm done.

Thanks!

That'll give you a theoretical roughly 2HP. Enough to move it around,
but -not- with much speed. Think 'trolling motor'.

OTOH, if you can fit one concentrator/fluidyne, maybe you can get 2-3 of
'em on board. Now, you're approaching the capabilities of a 5HP outboard.
That should be enough to leave a wake -- at least a small one. grin

My problem is that I'm not sure that'd be enough to pull a twin-hull

That hurts just to *think* about it.
