Topic: Room to clear right of way boat Posted: 21 Oct 19 at 10:38am |
Two dinghies are on port on a run parallel to each other. The leeward boat gained its overlap from behind. A close hauled boat also on port in another race is about to pass close in front of them. The windward of the two boats on the run requests room from the leeward to pass behind the close hauled boat. The leeward boat refuses.

Leeward is ROW over windward. She can go whichever side of the obstruction she likes, but must give room to windward to pass the same side. Edited by JimC - 21 Oct 19 at 11:16am |

I believe Jim is right, but it took a little cogitation and a diagram or two for me to work out why he's right. Far longer, in fact, than I would've had in the real world, which is half the point. An interesting situation, and the Case book doesn't quite cover it. Perhaps Case 124 is the closest, but Case 11 is also relevant. In this case all boats are on Port, so Rule 10 does not apply. The beating boat (B) will be to leeward of both the others (W and L), and therefore has right of way over both W & L. B is an obstruction to both W & L - 'A boat racing is not an obstruction to other boats unless they are required to keep clear of her' - but it is an obstruction if they are. 19.2(a) allows a right-of-way boat to pass an obstruction on either side. L can choose to avoid the obstruction by sailing either in front of B or by ducking its stern. As leeward boat L has right of way over W, but because L gained its leeward overlap from behind it is restricted from sailing above its proper course (Rule 17). If L chooses to duck B's stern, and W follows, L becomes the outside boat and does (if hailed) have to allow W to duck B's stern. But as right-of-way boat over W, L can also choose to pass in front of B. (The definition of 'Proper course' does not imply the absence of all other boats, only 'the absence of the other boats referred to in the rule using the term'. In other words, if W were not present, B would still have been beating to windward, and L would still have had to make the same choice about B; L's proper course might have involved luffing in order to pass safely in front of B.) In this case L would be the inside boat, and W has to give room as both outside boat and as windward boat. If L needs to change course by luffing in order to pass in front of B, it is still sailing its proper course, albeit one changed by the imminent arrival of B, and W has to avoid L. W cannot assume that L is going to duck B's stern; L has to wait until it sees L heading to duck B's stern before calling for room. Over to Brass to put us all correct.

Avoiding an obstruction is always a proper course... I think you managed to make it more complicated than you needed to. And there is no actual need for W to hail for room. L should be giving it as a matter of course. The only times a hail is mandatory is room to tack and protest. A hail will often help and boats should communicate, but there's no requirement.

Jim,
Completely accept your first point. I was trying to work through the options and the rules that apply. Easy to do in the calm of a garden shed; not so easy in the heat of the moment. Also works when everyone is on starboard, but not when the beating boat is on port and either or both of the downwind boats are on starboard. Also agree your second point - though I checked first - so far as the RRS go there is no requirement for a hail for room, but in a dinghy race, especially a single-handed one, the number of sailors with eyes in the backs of their heads is close to zero. If I were above and slightly behind a boat ducking a starboard-tacker, I would ensure that the boat below me knows I am there, or I'd tack off if possible. The rules do not require a hail, but unless I could afford a new boat every few months I'd make sure my boat wasn't about to become the filling in a sailboat sarnie.
