Offer: true go anywhere Trawler to build "side by side"

Yes!!!
How could you forget to mention my very sophisticated beef and beer cooling hold?

ahhh, these old straight, big monsters with open heads were a piece of art in themselves. And they made a special sort of music.
Say: Katuffel, Katuffel,Katuffel,Katuffel,Katuffel,Katuffel,Katuffel........
The best sound was made By the old Skoda, I can still hear them at the Bosphorus when some tiny old coaster is passing, music..........

the majority of ships engines are of the crosshead 2 cycle type

take a look, I think you are confused abt the type the type is the most mechanically efficient of any internal combustion engine up to 50%
http://www.marinediesels.info/Basics/the_2_stroke_crosshead_engine_explanation.htm

go out and listen those engines you hear in the Bosperous arew cross heads, if you know your diesels and , then you can tell how many cyls they have, often they are 3 and 5, these have a beat of their own,
and someone say torque
Maximum power: 108,920 hp at 102 rpm
Maximum torque: 5,608,312 lb/ft at 102rpm
that is torque, follow the link
and then there was the opposed piston eng Doxford, still in use many ships today

I have been to sea as engineer 2nd on small ships eng to 3000 shp , that was long time back, but large diesels I do have great love of
I can see what a truly Great engine, these larger cummins are on the rivers of eu many of the old German engines are being replaced by American, cats cummins
the long list of defunk companies goes on and on Carita originally had a pair of handed Paxmans 500 shp side Alaska diesel will one day be on that list, just another tiny maufacturer using Komatsu blocks

 

I was making atatement abt classes, 100-400, and so on, I was THEN not talking abt your boat, the fact is they were never made for smaller engines, the main advantahe being the huge stroke that could be obtained
we were talking diesels, none of the stuff DAN POSTED WAS REVELANT to your boat in his last photo either
threads lead places, we cant stay on one close parametre all the time , would be a dull lold place
was yapping to a young NA in Tr today, told me abt this new marina, near Bodrum
prces 14m berth 90 days 2400 euros, be empty a long time I would say
i cant rememebr all i say, or where, I am really polite to you, try it)
works well
never knew abt Ice BREAKERS? which? where and when, thsi is a serious question Do you know the Krasnir?

"..No having often the fund to ask a proper tank testing facility to test, I use model, scaled on size and weight distribution, and tested here on the pound. Sometime self propelled. It is amazing how just that simple test will show me the main character of the hull..."

It may surprise you but that is what my colleague and I do. My colleague has been doing this for over 40years, me just around 20. I am actually in the process of making my own test tank in my back garden, 25m long. Since i no longer have a pond close to me, nor my colleagues tank (he has one too). The models we make are identical, of course to the real thing, just as any full-on test house. Over the years we have found that our rough and ready tank test result are never more than 5% different with the real full blown expensive one we get done later to satisfy the contract for the client. We basically do exactly what Froude did many years ago...so not surprising the results are consistent. We offer this tank test service to anyone now...a quicker cheaper method of obtain results.

"...I choose for longevity, reliability and easy service!.."

The customer is always right, whatever the numbers say....i also fully concur with your appraisal. Very very few customers select this route. Many opt for initial capital costs or rather the cheapest initial capitol costs. Only to their dismay and annoyance in the ensuing years or running costs.

 

Your post is so important to me. I was slighlty reluctant to post about that, knowing that sometime it's confused with playing with toy boat.
Thank you, it make me very happy to know that you are also testing yourself your models.

 

"...knowing that sometime it's confused with playing with toy boat..."

We would always get funny looks from poeple (when we did this in the pond before using the tank in the back garden). Comments like..."oh..lovely...you with the model yacht club??"...or some walking by sniggering thinking, "sad grown ups playing with model boats".

To the uninitiated, everything looks odd and of no use...

Nice summary above, by the way.

 

Completely wrong Stu sorry! WE WERE TALKING DIESELS--- WE. When will you learn that I am not like you? And I am not like the average boater? I am no yachtie! I do what I do to commercial standards only, or I leave it.
And this is a thread about MY personal boat and a possible sistership. Here we discuss MY boat, MY diesel and MY issues and demands. When you do´nt like that, I have no problem if you leave. But I have a problem with completely senseless crap like marinas in Bodrum or elsewhere. You claim to be polite??? This was your fifth or sixth attempt to hijack the thread.

Of course I know the Krasin, who does´nt. Ermak and Krasin are the most famous vessels in that job.
The rest you could know since long, but as I said above, you do´nt read a thread before you contradict.

Thats the crux, not enough people have the balls to contradict the customer, and not enough customers have the backbone to stand a contradiction and follow good advice. I was brought up with our family philosophy that we are too poor to buy cheap. And I learned soon that this was one reason why we were not too poor to buy quality.
But you know, greed is the motor of the business, stinginess and stupidity the fuel.
So, let them buy the cr@p, and let me have what I want, peace in mind and smaller bills. (but bigger engines)

What should be wrong with it? As long as one is professional enough to know what he can NOT achieve, every way of trial and error is a acceptable one. And John and I agreed in another thread, that T and E is still a valid method.

Richard

 

out of curiosity wouldn't it be simpler to have a return circuit tank where the water is circulated past the model

one possible advantage would be that weights and balance could be changed simply by adding weights to rods that hold the model in place

drag could be monitored by something as simple as a postal scale and accurately too

thats the way boeings wind tunnel was set up

water speed could be changed and a lengthly test performed without running back and forth

baffles would be needed at both ends to smooth out water flow but these could be pvc pipe

if this isnt clear i could do a sketch

 

The benefits beeing as you said but some cons too. Slow to fire becouse it just takes more time to get water in motion than air. It also uses a lot more energy to keep it going. More eddies with water create some inaccuracy.

 

Now after whoosh has failed again to hijack this thread, we should not make it the Tank Test Thread. I did express my dislike with whooshs attempts in a negative feedback.

Can you imagine what this man offers here? Such a ship at that price is a gift. Even a plain commercial boat of that size will normally cost more.

To remember what this thread was for:

 

I do not think anybody but you thinks that Sasha,
and of course that ad zilch
ad zilch, I say look to my gallery when I want to prove a point of to show folk, of course you are far to smallk to admite there is some nice work there
AND YOUR work? none, you sit here all day with nothing better to do than pick holes
you have a tiny following of beginners, the real nice poeple have long seen trhough you, the pros
Saha, go to all my posts, I help all and 90 out of 100 appreciate that
I have mail in my pc that would blow certain folks cred away in this thread
but that is private and , so no I do not hijack theads at all, I could not care less what you or ad zilch say
And you add zilch you are the guy who told bob to cut up a warped girder because it couid not ne saved, he did what I told him to do, and saved a lot of time and money
You simply can not abide that I have you pegged)
might add that I am proud of what I do, yes room to do better
but thats what this site is all about boatbuilding and so far you have shown us TALK TALK TALK

 

I agree with Sasha.

Whoosh's post are always negative to anyone that disagrees with him or points out his prejudices etc or points out he is not contributing to a thread other than to say 'look in my gallery' or talks on subject totally unrelated merely to say 'look what i can do too'.....

and you take the reply to ancient kayakers dinghy query, absolute poppycock, you have never sailed have you? and you are abt as usefull in practical terms as a BSF thread on a Cummins engine
