Load Carrying Ability

[rayaldridge]

Isn't there a RO watermaker that uses some sort of water-driven power source? My memory is fuzzy, but I think it was some sort of drag and trip mechanism that produces a linear piston stroke.

I think Bob Beggs used a manual watermaker when he sailed a Tiki 26 in OSTAR one year. He claimed it was good exercise. I guess on a condomaran, you could hook one up to an elliptical trainer and get your charter guests to make water for you.

At the end of the day, everybody here is right.
If you want to carry the weight, you must design for it!
Modern monohulls loose speed very quickly if overloaded.

The ceapest way is to make your hulls longer, but eventually you have to make your cat wider, in which case you must make it stronger = heavier = more expensive so you must stop there and only carry the weight designed to be on board.

If you want to carry more water, get rid of the fat wife and get a slim younger one. That will in turn make you slim and you'll be able to carry more weight

Much like the 60 year old father of famed comic, Richard Pryor, who had a heart attack in the saddle with a teenage hooker, it could also make you dead.... and then the weight carrying ability of your cat is moot.

There's another hazard. My wife is incredibly clever with a sharp hatchet.

Like many other people I have also made that statement many times. But recently I have been wondering whether it is actually true.

Unquote.




After many years of catamaran cruising, I can't say I've ever heard that one. Is it a British thing?.

Probably a bit like looking at a VW Beetle and saying cars are ****-house for towing caravans.

Wow ! What a way to go. Some guys have all the luck. It kinda makes one look foreward to the first heart attack...

Yeeehaaaa

i found the lovely Laura from spain
maybe i should write to her and ask her if she wants to crew for me

[Manie B]

Just to get you guys up to speed

its probably THE most miserable winter day here in sunny south africa
thats why we are all indoors and going nuts

time to drink wine now

bye

Cheeeezzz Manie, you have to agree that gautengelengelengelengeleng sucks.

If it isn't the crime crippeling us it's the friggin weather. We had small hail a while back.
Well, maybe it was snow What is hard rain coming down in 2mm dia balls ?

"a bit extra weight usually makes very little difference to its performance. This is because most of the major parameters determining the hulls resistance:- the half entry angle, the length to beam ratio and the prismatic coefficient[**] vary very little with increased immersion. True the wetted surface [viscous drag] will increase but this is only important at relatively low speeds. At speeds above approximately six knots to the 25 to 30 knot range where we are often operating the major component of resistance is wave making drag, rather than viscous drag, and that is largely determined by the before mentioned parameters which do not change. In practice this means that the displacement hull form is particularly suited for long range, and particularly long range at speeds that monohulls can only dream of. However as the hulls are made finer and longer in the search for higher hull speeds viscous drag will ultimately become the major component of the drag equation. It should also be kept in mind that the add on weight of fuel, water and food necessitated by ranges of 2,000 to 4,000 nautical miles will result in high displacement/length ratios which will adversely effect performance unless they are allowed for in the design."

thought good to bring up in case anyone missed it
