[PSUBS-MAILIST] Islamorada Trip Report...

[Hugh Fulton via Personal_Submersibles]

We had the same issue with the Comsub and we put a guy standing on the stern of the sub like a waterskier which allowed us to increase the speed a bit.  Always a problem with a sub.

Cliff,

What if you used a vertical towing bridle attached to the upper lifting lug and the point below directly below it on the bottom of the sub? If the sub begins to tow sideways like it did when we were tied onto the top lug or the MBT plug, the towline will slide along the bridle and allow the sub to keep it's normal attitude instead of rolling or diving.  

 

For everyone else, the main reason we couldn't tow at higher speeds is that above about 5MPH the sub would tend to dive, much like flying a kite in reverse.
