"The reason I'm jumping on Gludy, is that however I tried to say 5 Knots is too fast, he didn't understand what I was saying. Quite what's difficult about "slow down" I don't know."
Because my whole point was that at 5 knotts with 10 m vis.
My seconf=dry point was that even if you slow down, and I gave the figures, it is still a dangerous thing to do - you still have very little time with a slow, unresponsive boat to get clear - look at the figures.
Seriously had this been on a course and i was asked to do it at 5 knots assuming 10m vis, I would have said I would not buoy hop as its too dangerous. The slower sepped below that means that any EP is going to be more in error as you are more influenced by the tidal stream etc and no matter how you allow for it, you would still have a greater error than when travelling faster.
That was the sort of discussion i was trying to get - those were the subjects i hoped to lead onto.

Moose - sound signals? What are they? - I learnt soimething about 5 blasts once so I just go around heading for boats giving them five blasts and they all get out of the way .... saves a lot of time having to learn collision regs etc. I have been trying to find a book and anti-collison regs but no luck so far .... I avoided the collision regs books as I really try not to collide..... /forums/images/graemlins/tongue.gif

Would love to stay and go through this all over again, but I've far more important & exciting things to do...there's a yoghurt in the fridge which goes out of date tomorrow.

No - no special rights being claimed at all ... anyway - at the time we're sailing you should be long gone ... or limping back...

No - I am out over the weekend so leaving Emsworth for the night - I reckon i could easily cross paths with you!!!

I doubt it .... as I'm likely to be in a smaller vessel inside the harbour ...

Which harbour fireball - just in case we plan to lunch there and do some practicer berthing?

I'd get out of Emsworth noon if I were you - don't want a close encounter with the cill to ruin your weekend. HW is 1300 Friday

Ok will do - I will be leaving on Saturday and then back on Sunday.
They have left me a single fender width to the next boat, then there is the cill ... so with it being the first time, i shall have heart in the mouth for a few minutes.

See you draw 1.8m so would aim to be out 1230 Saturday and tied up by 1300ish Sunday. There's a tide gauge by the cill

Just seen the 1.8m draught on another thread ... same problem as us then ...
There is the gauge on the cill - roman numarals - in feet - we got in no problem at all at 7' (but then didn't expect to have a problem)
Probably worth a walk around the sea wall before setting off if your at all nervous ...

Thanks Fireball.
I have taken a look when the tide is out - looks a bit like a small ditch but brought Drumbeat in OK.
I will ensure there is VII on the gauge.
I frankly never like the first few minutes in a new boat - I am always waiting to prang it!!

Round N+1 with Gludy about the blind nav.
Hi gludy
The so-called blind nav is as RupertW says and shouldn't tax you too much. But i agree the idea is galling.
Essentially, in clear vis, they start you somewhere and tell you your target. It's an exercise, not reality.
Nonetheless, at very few points would you be doing 5 knots. It's creeping creeping along, 2-3 knots maximum.
So, frinstance, if your target was on (say) the 10m contour, or they wanted you to gettem into harbour which handily tuned up by following a 5m contour, then allowing for the tide means you are lookng for (say) 7 metre. So, you find an easy route to that contour, say by going due north.
You are to a lareg degree in the hands of the helmsman here and you will find it easy with some, not so easy with others.
You have to gettem to call back with depth all the time, esp when at low speed you are following the contour.
Now, as to your specific question of 30m visibility or even 10m visibilty when can't see end of boat, well then you wd have to adapt. Obvious same wd apply in high wind - you would not praps go looking or targeting giant metal buoys nor lee shores with brick walls.
But that's real life.
The YM exercise is that you personally have no vis, the helmsman does. Take it from me, you don't do lettem do much more than 3 knots as target gets closer if that and sometimes you might easily want to stop the boat if you are near a audible marker like a bell or buoy with morse sounder. The distance log is often misleading too cos the target is further with the boat weaving abou to hold a contour so you have to be patient.
Back to real life, in limited vis. You wd do things like move very very tentatively towards a so-called fixed marker, from downwind/downtide for maximum control. But if this just wasn't possible you would have to adapt, choose a different target, all depending on exact circs.

Re: Round N+1 with Gludy about the blind nav.
All that understood tcm
I have that new fang dangled radio autopilot so could actually be over the chart table watching the depth on it - or for that matter steering the boat!!! Just a thought.

Re: Round N+1 with Gludy about the blind nav.
yes, i had some interesting gigantic cheat ideas but the exmainer and instrictors are too good. Also wd be suspect if you told the helm to bear say 323 true at 25knots and arrive at exactly the right spot in three minutes flat...
