Water ballast

No, that's not correct. There are a lot of cargo ships without water ballast system.I would say more, most don't need it.

 

Enlight us, which models?
Precisely water ballast is a big environmental issue because the risk of spreading non native or invasive species

Ship ballast - Wikipedia https://en.m.wikipedia.org/wiki/Ship_ballast

I exaggerated the claim just as way to expose that water ballast has widespread use while in sailboats is still a niche and people ignore it or claim isn't necessary when both floodeable watertight compartments should be the norm both for collision safety and water ballast

There are 100.000 merchant ships across the world, 13.000 container ships and 4.000 general cargo boats besides 42.000 bulk carriers and 29.000 oil tankers. Most of them unnecessary as landfills should be closed and agriculture and plant based textile can be local and oil eliminated.

35.000 of them use ballast water treatment systems BWTS while 20.000 doesn't

Yes , generally speaking we are against water inside sailboats and leisure crafts . With today equipment supply it's much easier to imagine effective solutions.

 

Who is we? Are you going to stay on cockpit and call all the crew to create lateral ballast during a storm going upwind?

Yacht clubs or regattas or few mass producing sailboat shipyards shouldn't decide if water ballast is used or not, and in storm a stability water ballast reduces jerking movements that make crew seasick and reduces hull stress

Usually is fresh water the problem because it creates rot so saltwater ballast in a wooden boat could be beneficial, besides a water ballast tank can be made with thin glass or stone veneer to make them waterproof so internal water doesn't go to the hull.

Usually sailboats use plastic bags for fresh water but these decompose in nanoplastics

 

Generally speaking.Lack of words so I wrote we. If mass producing sailboat shipyards shouldn't decide about water ballast , who will make decision?
Ain't very easy task properly design water balast.Can you imagine inproper use of this ? It was/will be used in some experimental or competition vessels .Mass production ? Depend of shipyard.

 

Who is "us"?

Again, who is "we"?

Perhaps a little more thought and consideration could be put into your posts.
There are spell check options and even grammar helpers for those with English as a second language.
They could prove beneficial to all.

You seem to forget you are speaking a latin dialect and you shouldn't impose any grammar rules to anybody and I wasn't speaking with you.

 

This is an issue about safety at sea and while shipyards have pressured governments to remove amateur construction with some labels or standards, the reality is that sailboat safety regulation has been oriented to having a radio call and leave the boat and account to 1950s car or cargo ship safety regulations.


All Sailboats should have watertight compartments that could be used as storm stability water ballast, besides series sea drogues and stern plates, and protocols and materials to repair hulls, rudders, masts, etc besides having safety posters in the cabin with plenty of information about these accident scenarios and ways to act fast, and all harnesses, anchors,etc and equipment safety information and loads. Some of these posters usually are found in merchant ships and aren't even free to download

All of this could be done with amateur construction so people could access free information and know the materials and construction they are using and so safety wouldn't be seen as expenditure as it happens today.

Instead there's almost nothing of that and most of sailors are moonwalking after being scammed by shipyards with fancy pictures and the title-owner-property-lifestyle fallacy

 

You say that sailboats have shopping bags full of water?

 

Hopefully we can get this to the question at hand and maybe Herreshock will stop hijacking your thread like is his usual behavior. The McGregor 26 made water ballast popular. They are nice sailing boats, and the system works because the beam is relatively narrow. They compartment gets flooded after launching and emptied at the haulout. One safety feature is that the boat has a double bottom. A hole below the waterline makes no significant difference.

 

100% agree . I have quite limited sea experience , once my niece was going across Atlantic , it was very first time of her sailing experience. After leaving Canarian Islands in the middle of ocean they loose rudder . It was brand new Polish shipyard sailboat , delivering to Caribean . I was cheering her to sailing and that situation scarrying me . Now I know many of sea accidents and know more about shipyards boats.
I hope nobody will stick saftey regulations nose into my boats.

 

Or just have the axle located sufficiently aft of the CG with the outboard mounted on the transom. Depending on the source the usual recommendation is 5% to 12% of the weight of the trailer (including boat, etc) on the hitch.

 

Please to all those hijacking the thread. Start your own political discussion about regulations.

 

This is so funny. I quote:

Guess what, this forum is mostly written in this 'english' language, however it was derived, and since it is through the Word Wide Web you are talking to everyone around the world, not a personal Email conversation, so if you really want anyone to understand you properly, you need to use the appropriate words, and phraseology, and sentence construction, and not exaggerate. Otherwise we, the rest of the world, on this site, in the World Wide Web, may not completely understand you, and may mis-understand you.
And another quote:
"I hope nobody will stick saftey regulations nose into my boats."

I have a 10 foot long sailboat, call it 3 metres long, where shall I put my protocols, and materials, and my sealed water tight compartments, and hang my informational safety posters ? How big should my cabin be to hold all your requirements ?
Not all 'sailboats' are the same, and not all ship yards are the same, and not all countries or professional associations are the same in their regulations, so sweeping industry wide demands suggested won't work, or won't be followed.
Get back to 'water ballast' talk, on this thread.
Although I do enjoy the 'Muppet Show'.

 

We non-English speakers try to communicate with the rest of the world as best we can, and often the nuances of the language, which we do not master, lead us to say things that seem silly or are difficult to understand. I do not think, it is my opinion, that we deserve reproaches for trying. But often non-English speakers are amazed at how poorly some English speakers express themselves in writing in their native language.
And you are right, let us try to take this thread, and many others, along the appropriate channels.
