Design of Towing Tank for Laboratory

[Frederick H]

Hello to everyone, I'm new to this forum and excited to learn it exists.

I am looking for a company that makes small towing tanks. With a size: 5-7m x 1m x 1,5m and focus on testing equipment testing. I'm attending to the design of the MIT small tank and the Singapore tank. Someone with their information can contact me, please. Any company designing small towing tanks contact me, please.

Appreciate all inputs and interest, thank you.

I also would be interested in small towing tanks. Considering 1:5 scale is the minimum useful model that is used, I cant think of many boat hulls that could be evaluated in a 7m long tank
That's less than 6 boat lengths for a small craft, which would appear to be totally inadequate.

I don't use the tank for the boat, I use it for the underwater test equipment. The technical requirements of the tank I want are not as high as the tanks being built. Do you have information on which company is making small tanks?

As your posts do not explain what type of underwater equipment you are testing, I am not sure if the following comment is applicable
As it APPEARS that you are trying to diminish the depth of the tank, you should Google Shallow Water Depth Effects. If your object is either too close to the sides or bottom of the tank, these effects can
alter the accuracy of the date.

You said "small towing tanks."
The scale effect is still a potential problem.

I know you guys are worried about technical issues but currently, we are building based on MIT small tank and the Singapore tank. In addition, my current problem is finding a solution supplier and manufacturing the product, and the technical problems will be completed during the process of working with the company. I hope to get any contacts about the suppliers who have built small towing tanks, along with any information about the MIT small tank and Singapore tank.
Thank you for your time.

Not sure I understand that assertion; we've been testing models in the 1:10-1:20 range in the David Taylor basin (and others) for many many decades.

This is the discussion that interested me when I was planning scale testing.

edit.
I just noticed that I missed a paragraph in my reply
Smallest model scale for representative tank tests ? https://www.boatdesign.net/threads/smallest-model-scale-for-representative-tank-tests.31921/#post-353172

There are another few scale model testing threads in the forum, that I refer to.
