As I said in your other post (which I can no longer find BTW) the tough part will be in the locks as has been said. Maybe if you have enough crew you could drop one of them off in the small boat prior to entering the locks and take it through under its own power? All of the OWW locks have pretty good open areas prior to entering them if I recall correctly. Should be plenty of room to maneuver.
BTW, despite what PS says (I doubt he has ever tried it or he would know) you can't get two POLY lines tight enough to make them impossible to untie if you do loop to loop. It is just too slippery, which is why the loop to loop works best for in that instance. It is tough to tie a good knot in it. Nylon is a different story. Poly sucks for everything except towlines.
Same concept and knot as a loop to loop connection for fly line to butt section or attaching a wind on leader on an offshore rig. I don't care how hard you pull on mono, the loops slip right apart, poly works the same way.
I don't want to overplay towing either...but better to do it the recommended way (by thousands of professional towers and what's taught by the USCG) and then after becoming experienced and comfortable...tone it down to whatever level suits the situation.
Oh I've tried tying poly a few times including loop to loop...kinda comes in handy in the towing and salvage business.....
If you have a loop in the end of a towline and place it over a cleat and are towing a skiff at 8 knots...I will bet good money you can't get that loop off the mothership's cleat to adjust the length of the towline while moving ...adjusting towline length is an important part of towing.in certain conditions.
And I got lot's of experience with poly knots and nylon knots in towlines...I've had both melt together and have to be cut apart where melted...the knot will come undone if tied correctly...even in nylon...but the material will melt if the strain is enough.
