I knew I cannot (and I didn't want to) compete with McIntyre in terms of popularising such an event and decided to go on my own - some of the restrictions of McIntyre's race are not for me.
Yeah mate I hear ya, I gave the Golden Globe some serious thought when it was first announced but realised that I don't really fit that kind of event. If I'd wanted to do it I could have gone anytime which is why I think the way you are doing it is spot on in that respect.
Myself I wouldn't have the long range weather info, just read the glass, sky and sea, keeps it even. I reckon the modern: cutter rig, sail handling gear, running rig and sails will be a good edge on what Robin had. All that time he spent stitching sails, getting injured handling the sails and repairing stuff. On fatigue management you'll do well let alone diet etc.
What an adventure though, inspirational

That is exactly what I want to check.

Personally, I'm not so sure about the effect. I do remember, how many boats started in the original Golden Globe, and how many managed to get back...

Re: Gravity tank for fresh water - any experience?

Love your passion mate, I'm just gonna take two odd years (1 to prep & 1 to sail) to go and check something.

You're welcome (trainee witch).

But your calculations are wrong. I bought my boat 4 years ago, so it will be about 5 years preparation and 1 year sailing.

Yes, some girls are a bit crazy

Re: Gravity tank for fresh water - any experience?

Yeah, If you're going out with a tank of water above your sink, make sure it can handle knockdown forces when full in a big storm.
That assembly will need some serious bracing.

Imho, a simple QUALITY foot pump would be a much better and simpler answer.
Henderson or Whale pumps both get my vote.

(...).
Appreciate the concern- but I would appreciate even more if that would be preceded by reading posts in this thread.

Then you would know that nothing will need serious bracing, because the planned gravity tank would use an empty space created by construction of the boat. But even if it would be a separate tank - it would not need any bracing being placed under (and against) the deck. In short - in any configuration the tank has nowhere to go, irrespective of its weight.
So yes, it will be able to handle with ease any sudden movement and forces such movement causes. Including 360 - gravity tank is one thing of which I won't worry in such a case

If you say so.
BTW I have read the whole thread.

Obviously not the whole. That is first page.

Re: Gravity tank for fresh water - any experience?

And said space is strong enough? Was it designed to hold 5 gallons of water in a knockdown?
Interior pics of your cement Westsail would help.

LOL. You get the answers that you pay for whether you like them or not. That is the nature of a forum. Are you going to argue until you get a quorum to agree with this kluge of an idea? Or are you trying to convince everyone else to agree with your idea? You can throw a temper tantrum fighting answers you don't want, and you will still get them.

Personally, I think you're trying to solve a problem that doesn't exist. You don't trust electrical systems and pumps and want high availability. You don't want manual pumps either.

The flaw in your plan is the ability to refill the gravity tank from the main tanks.

If I were so concerned, I would keep a hand-pump available. Should I loose a pressure pump or electricity, I would hand pump water from the main tank(s) to a 'day tank' as needed. If you don't use it, it shouldn't need servicing. Check on its function from time to time to be safe.

Re: Gravity tank for fresh water - any experience?

Shrew, thanks for that, your answer in contrast to some others has something to do with the thread. I don't mind people not agreeing with me, quite opposite - I learn quite a lot from them. But there is difference between your answer, giving your take on the topic and answers "it's rubbish because it's not electric" - often given without reading other posts.

So don't be surprised that I don't really like if someone wants me to take them seriously at the same time when they show they are not taking me seriously. I'm happy to DISCUSS different ideas, I'm not interested in trying to prove I'm not an idiot. If someone thinks that, that their right, but if they say it out loud - they should be ready to hear back my opinion, which maybe similar.

And please, don't teach me what is the forum and how should I behave. It is my choice, not your dictate.

Agreed in full, except that it is early morning here, so I'll make toast, not popcorn.

OP, sounds like you are the dictator here, not Shrew who was being supportive. You have received some useful advice as well as the usual garbage. My advice is to ignore the garbage rather than rail against it, for the latter serves no useful purpose and tends to drive away those who wish to help.
