So other then the definition there is not much a out sailing around the course. And 18.1a
Does point towards that is OK to do it? |

That's how I had it, if S tacks under P he'll be vulnerable to S rolling over him on the reach so by forcing P to double tack he gains a little ground.

Yes.
Looking at each of the rules: None of the rule 18 rules apply because rule 18 does not apply, by rule 18.1(b). Rule 17 does not apply because boats are on opposite tacks. Rule 24 does not apply because no boat is taking a penalty, sailing on another leg or subject to rule 21. So no way does proper course apply in that scenario. Case 9 sets this scenario out. When a starboard-tack boat chooses to sail past a windward mark, a port-tack boat must keep clear. There is no rule that requires a boat to sail a proper course. Sam and others, over to you for the tactics, but I do remember that Stuart Walker said "Cross 'em when you can". Edited by Brass - 28 Sep 20 at 3:56am |

It makes sense to me if you can end up ahead and to windward, however briefly. The only time being to leeward pays is if you have a solid lee bow upwind and, even when you have, it takes a few lengths to consolidate an advantage.
If I was P here I'd force S to stand on and duck his stern, if you're a length to windward of the layline you have room to do so. A cute helm in S would slow down to prevent you from doing so though... Edited by Sam.Spoons - 27 Sep 20 at 11:25pm |

It's a pleasure.
Hopefully you can encourage your friends at the club to take a look at the current rulebook <g>. |

If the port tack boat luffs and slows, chances are that the starboard boat will tack into the gap, allowing port to bear away again, so losing less ground than having to put a double tack in. Especially likely if starboard is defending from behind, too.

What will happen/has happened is the startboard tack boat always carries on sailing to make the port tack boat tack away.. As soon as this happens starboard then tacks back.. Regardless of port luffing.. Etc |

As Port, on or above the layline you are in a strong position. If you can't cross S then you have two options, tack or duck. if you hail for Starboard to hold their course* and duck their stern, by the time they've tacked, a couple of lengths past the layline, you'll have that strong lee bow I mentioned** above. S has two options, either slow down so you have to tack or to tack into your lee bow.
* No hail is necessary but it clarifies your intentions and reminds them of their obligations under Rule 16. ** And be RoW boat. It's not infallible though, if they can tack fast enough to avoid the lee bow and roll you on the next leg.
