[PSUBS-MAILIST] Towing...

Wed Sep 9 16:34:04 EDT 2015

Vance,what about towing from a low point at the front?One of my thoughts was to have a low frontal tow point with a short lengthof rope from it with a clip on the end. This is clipped on to a higher point on the subwhen not in use & clipped on to the towing rope when needed. This is so that you don't get wet trying to attach to a point below the water line.Alan

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.Jim In a message dated 9/9/2015 1:10:29 P.M.

| 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.   Vance

     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.  Vance

      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.   https://www.youtube.com/watch?v=ApUnGjTb4DQ

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

      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
