Tricky harbour entrance?

They'd have gone straight through if it hadn't been for the skipper's balls bouncing off the walls on each side.
 
Typical effing sailors; never have enough fenders out. Actually I know exactly where that passage is because we've been to Mali Losinj a few times whilst we were in Croatia. Its totally stupid to attempt to use the passage in a Bora wind and those yotties got everything they deserved. It only adds a few miles to any trip to go around the bottom of the island
 
It's all to do with Kelvin waves, where transverse and divergent waves from the underwater hull 'suck' the boat towards the nearest solid object. This sets up an oscillation as the helmsman applies opposite lock, then everything goes ding (port), Ding (starboard) and DING (port).


It's why RAS is such a complicated and mathematical exercise in steering big ships.

Dutch Barge in shallow and narrow canals much the same. Only solution is to slow right down.
 
Been there two.
In fact we spent the night on the quay just to the right of shit as the video starts
Lovely place but not in those conditions

I guess a nice place, but may be a bit smelly?
 
Whitelighter, your pic shows Osor. It links Cres and Lošinj islands. You'll never see such sea conditions at this place. Whereas the video was made at the Privlaka passage on Mali Lošinj.

Another video, with more success this time:

And here, with some serious Bura:
 
All in all I figure that is much more pleasant to be a spectator at this place rather then be THE participant.
 
Imagine successfully negotiating that channel in atrocious conditions only to find the swing bridge is closed
 
so glad getting into the Hamble is more straight forward than this...
The funny (well, relatively) thing is that the channel in the video is not the main harbor access, but just a shortcut to avoid going round the island. A few miles difference, as Deleted User said.
The problem is that when Bora blows, on top of the waves, it creates a rather strong current towards the S side of the channel, where the sailboat is heading, inside the large natural harbor.
As a result, even if in the video the sailboat seems to be going relatively fast, I bet that her STW was actually extremely (too?) low.
But of course, aside from the huge balls that would have been necessary to go through at full throttle, any damages would have been even worse... :ambivalence:
 
As an aside fenders just hanging off a clove hitch are useless in this sort of higher speed/side swiping a wall situation ( you need steerage way so maybe in a sailboat WOT).

So, if you were tackling this how would you rig your fenders - or would you not bother at all rigging fenders?
 
With 10hp, a narrow rudder and a belief that your're safer at sea, such stunts are not for me but were I daft enough to try it, I would rig my fenders horizontally and secure their lines to something more substantial than the guard wires. I'd also want my crew to sit down and wear life jackets.
 
...a rather strong current towards the S side of the channel, where the sailboat is heading, ...
Perhaps better* to go in backwards, with forward STW. At least the impact with the concrete would be less dramatic and more fender-able.

*All relative of course - best choice is the main harbour entrance!

I have heard that some barges go through bridge pylons in reverse when the mighty Rhone river is in full flow.
How about this, put all your fenders on the side that the wind is blowing you onto. Come along side and just creep along the concrete wall.
