The allocation engine can only work with what you give it. Twenty minutes of thought before a nomination round closes is worth more than anything you can do afterwards.
A few weeks before each four-month cycle begins, nominations open on your boat. The owner app shows you the calendar for the cycle ahead and asks you to rank the days you want in it. The round then closes, the allocation runs, the result becomes viewable, and finally the cycle goes live as the calendar you plan your summer around.
That sequence is worth understanding because only one part of it is yours to influence. Once the round closes there is no queue to join, no page to refresh and no button that puts you in front of the other owners. Everything you get out of the next four months is decided by what you submitted, and by what the other three to seven owners on your boat submitted.
Which is good news, in a way. Nominations are the one moment in the cycle where thinking harder than everybody else genuinely pays, and most owners spend about four minutes on it.
Not every day on the calendar is worth the same, and the system does not pretend otherwise. Your entitlement for a cycle is counted in buckets rather than as one undifferentiated pile of days, so a weekend day and a wet Tuesday in June are never traded against each other by accident.
Fridays sit in a bucket of their own. A Friday is a workday for most owners and the front end of the weekend for the rest, and if Fridays were simply pooled with Saturdays and Sundays the owners with flexible work would quietly absorb everybody else's weekends over the course of a year.
Public holidays are counted as weekend days, whichever weekday they land on. Anzac Day on a Tuesday, the Monday of the October long weekend, Australia Day in the middle of the week: all counted as weekend days, because that is what they are in practice. The alternative is a system that prices the best boating day of the autumn as an ordinary midweek.
How many days you get in each bucket scales with the share you own. Shares across the BSA fleet run at 10%, 12.5% and 25%, and a quarter share nominates against a larger entitlement than a tenth does. That is the whole basis of the arrangement, and it is visible in the app rather than negotiated at the dock.
The most common mistake in a nomination round is ranking only the days you actually want. Six Saturdays, the Australia Day weekend, done. The trouble is that those are the same days every other owner ranked first, and once the engine has resolved the contest for them it has nothing left of yours to work with.
Rank well past your entitlement. If you expect a dozen days, rank thirty or forty. A long ranked list is not a promise to take forty days. It is a set of instructions describing what should happen to you when your first choice goes to somebody who wanted it more, and the owner who supplied those instructions gets a better second-best than the owner who did not.
The order is what carries the information, not the length. A list of forty days ranked carefully tells the engine which weekend in March you would trade for which weekend in April. A list of forty days thrown in without thought tells it nothing at all, and you will get days you did not really want but did technically ask for.
There is a temptation to play the round tactically: to rank a Wednesday in May above a Saturday in March because you have decided the Saturday is unwinnable and you would rather not waste a high rank on it. Resist it. If you rank the Wednesday first and you are given the Wednesday, the engine did exactly what you asked, and it will never know that you would have preferred the Saturday.
The balancing already happens on your behalf. The allocation is looking at the whole cycle and every owner on the boat, spreading contested dates rather than handing them to whoever has the cleverest strategy. Honest ranking is the input it is designed for.
The other underrated move takes five minutes and happens off the app entirely. There are only four to eight of you. The owner who exclusively wants school holidays and the one who takes the boat out on quiet Thursdays are not in competition at all, and a short conversation in the group chat before the round closes routinely does more than any amount of ranking strategy. Syndicates that talk get more out of the same calendar than syndicates that do not.
Worth saying plainly: there is a version of this where no amount of good nominating helps you. If the only days you can realistically use are the same handful everyone else wants, every year, then you are permanently in the contested pool. Christmas week, the Australia Day long weekend and the Saturday of Easter are wanted by every owner on every boat in the fleet, and a fair system spreads them rather than manufacturing more of them.
If that describes you, the fix is not a better ranking. It is a larger share, a boat with fewer owners on it, or the acceptance that some summers you will get the second week of January instead of the first.
There is also a smaller, more honest catch. Ranking days is planning, four months ahead, three times a year. Owners who genuinely cannot think past next fortnight tend to find nominations irritating no matter how well the engine performs. Day swaps exist precisely because plans change, and they take the edge off, but they are a release valve rather than a substitute for turning up to the round.
A few weeks before each four-month cycle starts. The round opens for ranking, then closes, the allocation runs, the results become viewable, and the cycle finally goes live as your calendar in the owner app. Only the ranking stage is yours to influence.
Many more than your entitlement. Ranking only your first choices leaves the engine nothing to fall back on when another owner has ranked the same day first. The order you put them in matters far more than the length of the list.
Yes. A public holiday counts as a weekend day whichever weekday it falls on, so the October long weekend Monday, Anzac Day and Australia Day sit alongside Saturdays and Sundays rather than being allocated as ordinary midweek days. It reflects how those days are actually used.
Yes. Entitlement scales with the share you hold, and shares across the BSA fleet run at 10%, 12.5% and 25%. A quarter share nominates against a larger entitlement in every bucket than a tenth share does, in weekends, weekdays and Fridays alike.
