Lock Surges

I rather think that depends on the length of the boat.

 

If it's short enough not to be an issue then there wouldn't be the problem with the boat getting knocked around so much. Also it still stands, even a shorter boat is more controlable with bow and stern lines.

Best way is to go up with another boat, that stops you banging around. Only problem is that finding another moving boat on the KandA can be tricky!

Thanks. But the problem is surging backwards and forwards. It is being pushed across the lock and hitting  boat on the opposite side to the one Iits being held. 

He says his problem is hitting (his) boat on the opposite side side - no mention of a sharing boat.

 

There is some good advice in this thread issue, but anyone who thinks he stands, take heed lest he fall, as whenever you think you have a fine technique, it will go embarassingly wrong before long.   The odd bang rarely does any real damage providing the crockery is not stacked high on the draining board.

I misunderstood what he meant when he said "hitting the boat on the other side", I didn't realise he meant "hitting his boat on the othrt lock wall"

Doesn't that depend how many crew there are?

One locking and one steering is enough.

 

Take a long line from the bow, around one or two bollards and back down to the steerer.  It's easiest with a handrail to take a turn round, but I have fitted cleats there for some boats.

 

There is a staggering difference in control between this long locking line and using a centreline, because of the extra leverage.

Good point, which I shall bear in mind at our next wide lock. Still, I haven't had a problem using exactly that technique, but with the centre line (on a 48-footer).

Try it if you have a long enough line.

 

A sub 50 foot boat should usually be fine in broad locks anyway with a couple of notable exceptions.  The bow isn't usually in the full force of the water from ground or gate paddles.

Last time we came up a flight of wide locks we strapped two boats together side by side and left one crew member aboard to control both boats using just one engine - it worked for us . . .

My much preferred way in wides, fine till you get to the Blue Lisa bridge!

Watching and helping 70ft fuel boat up the Caen hill flight, boat enters lock, gates closed, boat reverses back to bottom gates, bow tied of to bollard tiller hard over to keep stern against the lock side and forward gear engaged and some revs applied, both top paddles opened fully no problems, boat stays up against the lock side. You do need GOOD rope for this.
