A Sailing Yacht for your Water Worlds

A sailing ship you could use on a Water World or other-worldly oceans.

Looks like a grand way to survive the apocalypse.

Is there a link to a set of deckplans that I've overlooked? Otherwise it's not very useful to me. Pictures are nice but deckplans are a lot nicer.

Meh. Give me the Flying Cloud or the Cutty Sark any day.

The first link goes to a page that has a picture of the deckplans, but you can't zoom in on it. Might be in one of the other links.

VEEEERY Nice

Yay - I could use some of these in some Worlds I have in my "krisyverse"

This is - an S.F. Game on another Site.

Borrowing from "Silly" or Fun Names on this Site - we are starting to colonise the Omega System.

We are starting with Omega II - only 40% water coverage. This will be a nice, heavily Industrialised Planet.

But the "Water Worlds" will follow --

Omega III is full of Fish, 95% water coverage - so "Piscemund".

Omega IV is even wetter - 99% water coverage - so "Panthalassa".

Big Ships would be very useful on these Worlds.

And I REALLY DO Hope the Colonist like Fish - coz they are gonna be eating an awful lot of Fish.

I would always worry about storms on a large water world. Given the seismic activity could create one big rolling tsunami disrupting transportation for months...and especially on a low tech world that is incapable of living under the seas...we had a thread about Planetary Disasters...

Having the Roaring Forties worldwide would be nasty.

At sea they're almost unnoticed. A tsunami needs shallows or an actual coastline to become the killer wave of Hollywood legend and current events.

A truly 100% water world, if any exist, wouldn't suffer much or at all from tsunamis and a truly low tech society wouldn't be living on such a world in the first place.

On a water world, tsunami's would have no real effect.

 

[Mithras]

Good point ...

Water World ≠ Panthalassic, tho panthalassic is a subset of water world.

Water World, for traveller purposes, merely means less than 5% land surface.

Tsunamis could be really important... if there are large shallow areas with small island groups.

Tsunami get noticeable any time the depth is less than the wave height.

So it all depends on just how deep the water is on that water world. On a panthalassic world with 2+ miles almost everywhere, sure, a tsunami is a non-issue.

 

[E.D.Quibell]

Storms, Prevailing winds and jet streams that are likley to be the main issue. Those and rouge waves.

In the Southern Ocean the waves and the winds are the killers because there is no land mass stopping them from just keeping going round and around.

What I don't know is if it's the land mases that make the weather that creates the prevaling winds that cause the huge winds and waves, or if it's because they are spinning around antartica that makes them so dangeraous.

However on a water world if you presume that there are weather patternes and prevailing winds then it's these that are going to create the waves and storms that are going to be the issue.

As rouge waves are (presumed to be) created from the focuseing of the wind, waves and current in the deep ocean it's likely that these will be the real killers.

Probably true, unless it has submerged continents resulting in 'deep ocean' and 'shallow ocean', then some places might experience Hollywood-like Tsunamis.

and a truly low tech society wouldn't be living on such a world in the first place.

I respectfully disagree.
An icecap could supporting an Eskimo-like culture.

The Aztecs built a floating city on a lake at TL 0 (pre-metalworking) so a 'barge city' seems plausible at any TL.

TL 2-3 seems more than adequate for a worldwide civilization of seafarers, like the Scandinavians, living off fishing and whaling.

[The existance of a human supporting ecosystem in the first place on a world covered by DEEP oceans requires far more handwaving than a low TL civilization.]

It would have to only a few feet deep and a very sharp shelf. Places large ships wouldn't go anyway.

 

[rancke]

I heartily recommend "The Blue World" by Jack Vance for an example of a completely covered water world.

(That is, I recommend the book as a good story and the world as an interesting setting; I make no guarantees about how realistic the world is).

Can you site any source for such a 'matter of fact' opinion?
I am not so much challanging your statement, as the Engineer in me just wants to know How Deep the deep needs to be and How Shallow the shallow needs to be, and how big the wave will be.

IMO, a wave rolling across a 4 km deep super-ocean and into the Gulf of Mexico might pose a hazzard to a trawler fishing in the shallow waters.

Note that the Tsunami in Alaska in 1964 was visible by the time it hit water 100' deep, and further; the speed slows rapidly and the influx builds rapidly. Basically, it becomes visible hitting the continental shelf, and dangerous at still navigable depths; when it hits shore...


Wind waves are different; when amplitude is more than median depth * 0.8, you no longer have free motion to complete the circular path, and the wave forms a breaker. Or, in cases where height/wavelength exceeds 0.17 in a 1G field. (I recall that that is adjustable by local gravity, but don't recall the corrections).
