Why not to have a bank start with no inner distance mark Print E-mail

Its best not to set a start line from the bank without an inner distance mark at a generous distance from the bank, no matter how well placed the start line would appear to be. The reason for this comes in the introduction to Part2 C of the RRS - At Marks and obstructions. This says "Section C rules do not apply at a starting mark surrounded by navigable water..." The significance of this is that if you have no inner distance mark then the part C rules apply, and boats are allowed to "barge" in at the start boat and ask for water.

 

The interactions of rules 18, 19 and 20 in this situation appear to me to get very complicated indeed (and R15 & 16 come into the mix as well), and I am not sufficiently confident to be able to offer a guide to who has what rights in the situation below. Instead I am just presenting a diagram showing the sort of positions that boats can get into, and what they might be saying to other boats.

 

Graphic: Start line antics

 

The only advice I can offer for a situation like this is "don't let it happen". A lot of race teams seem to get hung up on setting the start line exactly on the final mark, and this can leave a start line which gets fearfully close to the bank and gives the less agile boats and less experienced sailors very little room to play with. I suggest that a start mark should never be set less than about 50 yards from the bank or another obstruction. If that means moving the start line 50 yards up the first beat from the last mark then do so. Even if you are average lapping boats then the tiny difference in distance cannot make any difference to the results, so its much better to set a line with plenty of space round it, which is safer and fairer for everyone.

Quoting Chris Smith:
...allowed people to hold on to the pontoon giving them a significant advantage.

There's not as big an advantage as you might think... I considered that but didn't do it in the end. The fly in the ointment is R15 - A boat that acquires right of way must initially give room to others to keep clear. If you "un moor" and gain right of way you must initially give all other boats room to keep clear. It might be that the only way of doing that would have been to stay moored up until all the others had gone...
I *think* in this case the jetty/commitee boat would have counted as a continuing obstruction so Rule 19 would apply or possibly rule 20 instead. I did try to work out the rights and wrongs of it all but it hurt my head too much... We could ask the RYA for an interpretation of the rules, but it would be better if it just never happens again...

Committee boat was a mark, but not one surrounded by navigable water as in rule 18. That means the usual anti-barging rule does not apply and we are back to the basic rules about avoiding obstructions.

I have many times said (and it says it in the Race Officers Guides) Do not set the line too close to the bank. It is not fair to the less manoeuvrable boats like Canoe and RS600 as well as causing potential mayhem.

Entering the start zone was like the Bermuda Triangle - only on port and no sure escape. We spent loads of money on the Committee boat - let's use it. It could have been at the port end of the line with Mark 1 as the OD. The flags on the C/boat are not so convenient like that but too bad, you have to look across the boat to see them. If there is no ID, isn't the C/boat a starting mark ? If not, we need an IBRSC exemption to the ISAF Rules to make it one.
