Uncle Al's Rules in Pictures!
In his long sailing career in the Wayfarer Class, Uncle Al has collected untold number of pictures to illustrating every rule in the book. He has just finished updating "Racing Rules in Pictures" for the 2009-2012 RRS.
In the photo above on the left, 1305 (starboard) is an obstruction to 1131 who is on port tack. Therefore 1131 would have had the right to hail 171 for "room to tack", had he done so well before the moment captured here. Having not hailed, 1131 is now blissfully sailing into a situation where he is sure to foul the starboard boat (1305) since he's left it too late to bear away, or he will foul the boat to windward of him (171) by doing a crash tack (see photo on right) to avoid 1305.
This material is intended as a practical guide of the basic Rules necessities for his fellow Wayfarers, but just the same, he hopes that a few of LTW's readers might enjoy looking it over and sending him (uncle-al3854@cogeco.ca) word of any errors they may find. He has done his best to proof-read but the extra eyes would be welcome.
I suggest you have a look, it is worth it!
... still working with 2 lenght zone... I suppose need Ungle need to upgrade it
ReplyDeleteReally enjoyed going through parts of your rules book - what a great job!
ReplyDeleteI noticed in one slide in the mark rounding section that you mentioned
Note however that the boat which is or was clear ahead (e.g. Hans Gottschling, W938, in the photo above) is not entitled to tack as part of its rounding procedure - see the last sentence of 18.2(c): "If the boat that was clear ahead passes head to wind, rule 18.2(c) no longer applies." - which means that rule 13 does apply (see ISAF Case 81) and if Hans tacks here, he may well foul Peter Rahn (W286).
I think the language you quoted is from the 2005-2008 rule 18.2(c). I know there is discussion especially in college racing (the "Move") about the new rule which reads, "However, if either boat passes head to wind or if the boat entitled to mark-room leaves the zone, rule 18.2(b) ceases to apply." UCSA may have changed the rule for team racing, but I don't know of any universal change to the ISAF rule 18 that would support your scenario.
Perfect! This is what I need - a fresh set of eyes. I have changed that paragraph as follows - updating the quote to the 2009-2012 version:

The mark-room definition further underscores this as follows: "mark-room does not include room to tack unless the boat is overlapped to windward and on the inside of the boat required to give mark-room."
I presume you had something like in mind?
Thanks again, Dave.
Best regards,
