[PSUBS-MAILIST] Towing...

[via Personal_Submersibles]

James,
Before you weld towing eyes on the front of your battery pods,  you might 
try making some circular clamps to go around the front of each pod and  
attach towing eyes to those.  
That way you could test the concept first and possibly refine  it.

If you pick up those three towing points so that everything pulls  evenly 
in calm water, it will go a long way toward keeping things stable  when 
things start pushing and pulling in different  directions.

Thanks Vance, 

I did think of maybe towing from the battery pods.  Maybe i'll  weld on a 
couple of towing eyes.  Something else I should have  thought of before..... 

will check out options later. 

regards 
James

The force applied that high and that close to the center of  gravity will 
make her dive and squirm. Pull hard enough, she'll crab  out to one side and 
roll toward the boat. It will be hard not to spill  your tea.

That's what I was thinking.  However, there is a video of  someone towing 
Bionic Guppy and they are pulling it from the lifting  eye.  Different boat 
though.

Hi James, 
I think you need to tow from the front leading edge to  avoid crabbing.

Hi All, 

Has anyone towed a K boat from the forward lifting eye?   

I am going to tow my boat to a better  diving location.  I think the best 
place to tow it would be the  very front, on the hand rail mounting post.  At 
this point  there is a 20mm stainless bar bolted through the forward tank 
and  into the framework.  Although its a thick bar, I have a feeling  it 
might get damaged if I tow the boat from that point.   Forward lifting eye would 
be better but ive got a feeling it might  now tow very well. 

Any thoughts? 
Thanks 
James
