Think you missed the point. No boat of any kind can get to the south pole.

didn't miss the point, was just wondering if they move much (nice to hear that they do)

how long and how many liters of fuel would it take me to get from manchester to the south pacific in a sunseeker 60 or something similar ?

I think I read on this thread that some big ones like Eclipse can cross the Atlantic on a single fuel up and it would cost something in the region of half a million quid to do so?

To people who know more than me - Is that right?

We burn 60 litres per nautical mile (in car terms I think that works out to 0.087 mpg) on an 'economical cruise'. Double that if in a hurry.

£500k, about the same as a scheduled first class plane ticket..........

Ulysses quoted range is based on 55 per from what I've read. It's range being 8500nm. UK to NY is what, 3,200 give or take so no problem at all. A pretty boring trip I would think.

I know this is probably a stupid question but why are they so bad on fuel?
Is it the weight? Resistance against the water??

Yup, water is heavy and needs a lot of energy to move out the way.

Boats which can plane (ie run on top of the water) are faster and more efficient when planing than at slower speeds with the hull in the water.

Essentially because we are pushing hundreds of tons of steel, aluminium and Dom Pérignon through a fairly viscous fluid.

And water itself if it has a pool like some do

My fishing boat was 10m long and had twin 300hp v6 outboards. At 30 mph if would sip 80L of petrol per hour. At 50mph it would run 150l per hour and wide open it’s 200l. Think about the friction from water and you get a lot of slip from propellers. Very inefficient

I just looked up Ulysses specs. Twin diesel electrics. Each engine is 8000 kg, 69L displacement. V16. Imagine the fuel it uses just purring along at 1,300 rpm.

The two happiest days of a boat owners life...



But it's all relative.

Using the hypothetical example of an owner worth 1B , and spending 5M pa on running costs and 5M during the winter for 'servicing'.

This is essentially the same as an individual with a net worth of 1M , spending 5k on running their Porsche, plus 5k for servicing.

Or your average man on the street with a net worth of 100k spending 500 on running their Golf, plus 500 on a service.

So sailing yacht A and Maltese Falcon etc, must exist because their owners are too poor/tight to buy fuel and want free power


So in the drive for efficiency, why are there no hydrofoil super yachts - actually answering that myself - its probably massively inefficient to get the thing up on the foils.

But here is a really cool idea - an Ekranoplan syperyacht - do it right and it would be supercool. They can be big, fast and would easily shout "fk off peasants" to the rest of the world.

I've always thought the way to really make an entrance these days would be to land an Empire Flying Boat between all the yachts anchored off Pampelonne Beach.



That would show them who's boss. Helicopter? pah!

Indeed. It’s the relativity which is hard to get over, but once you do it’s fairly normal spending levels considering net worth.

I build houses for people who own such yachts and what they spend their money on at home is just as mind boggling as the yachts. 3m high, 3 inch thick internal doors (Italian walnut with brass and gold inlays) @ £5000 a piece x 100 doors in the house say or million quid swimming pools with moving floors so they turn into ballrooms....

Relative to me taping sheet of cardboard over my door opening or having a bath

Sailing Yacht A

https://en.m.wikipedia.org/wiki/A_(sailing_yacht)

Fugly in the extreme but certainly qualifies for this thread!

SYA has certainly been covered a few times on this thread and has caused a stir for it's design. Personally I think it's remarkable. But each to their own!

what's the freshwater capacity vs fuel capacity etc?

also 330 nautical miles seems absolutely crap, do people only do proper journeys (uk to south pacific) in much bigger boats?

looking at the globe it actually seems quite a dangerous journey to just head out in the middle of the sea - you'd be better sticking not too far away from the coasts where possible to refill etc on your way to the south pacific from the uk right?

Not sure you’d want to try and cross an ocean in something like that anyway!

Use one of these if you want to take your little boat from the med to the Caribbean.

It's capable of handling a decent sea but not designed to go 500 miles+ offshore. It could easily have a water maker on board for showers and hold 500L of fresh water/2000L fuel. Something like that. Even this boat is £2.5M range i would guess without looking it up.
