Riviera is the most heavily represented builder in the BSA fleet, and its model numbers are close to a length in millimetres. Here is what each step up actually gets you.
Riviera builds on the Coomera River on the Gold Coast, which is a short run up the river from the fleet's Sanctuary Cove berths. That proximity is not sentiment. When a boat has to be back in the water for the next owner's allocated weekend rather than whenever a part clears customs, a factory, a dealer network and a service department in the same time zone is worth a great deal.
The naming is also unusually easy to read. Riviera's model numbers track length, so a 4400 is smaller than a 5000, which is smaller than a 5400, a 5800 and a 6000. The M400 sits below all of them as the older, smaller sports cruiser in the range. In the BSA fleet the Sport Yacht designations — 4400SY, 4800SY, 5000SY, 5400SY, 5800SY, 6000SY — describe boats with a low sports bridge rather than a tall traditional flybridge.
What follows is not a spec sheet. Cabin counts, engines and hours change from hull to hull, and the fleet page carries the current details for each vessel. What does not change is the shape of the decision each step up represents.
At this end of the range you are buying a day boat that happens to sleep people. The cockpit seats the group you actually take out most weekends, the saloon is somewhere to get out of the sun, and there are berths for a night or two if the weather is kind and everybody likes each other.
This is the right size for the way most harbour owners really use a boat: out mid-morning, anchored somewhere sheltered by lunch, back at the berth before the seabreeze makes the run home unpleasant. From The Spit that is Chinamans Beach or Grotto Point; from Rushcutters Bay it is Shark Island or Camp Cove. Neither trip needs sixty feet of boat.
Somewhere in the low fifties the boat stops being a day boat with berths and starts being a boat you would choose to sleep on. The master gets a bed you can walk around, the second cabin becomes somewhere adults will genuinely stay, the galley can feed eight rather than reheat for four, and there is enough freeboard and weight that a lumpy afternoon is uncomfortable rather than unpleasant.
That combination is why this band carries a lot of the fleet. It covers the two use cases most owners actually have — a harbour day with friends, and a long weekend at anchor on Pittwater or up Cowan Creek — without being a boat you feel you should apologise for taking out with four people aboard.
Above about fifty-five feet the boat starts making decisions for you. It rewards being taken somewhere: an overnight run north, a week in the Whitsundays out of Airlie, a long stretch at anchor with real accommodation for two couples and their kids. It also asks more of whoever is driving, and more of whoever is docking it on a windy afternoon.
This is where booking crew through the owner app stops being a luxury and starts being the reason the boat gets used. A skipper, a hostess and a deckhand turn a vessel you might hesitate to take out into one you take out constantly. If you would rather drive yourself, you need a current NSW boat licence — the same licence you would need for a boat you owned outright — and, realistically, some hours at this size before you enjoy it.
Ask yourself one question honestly: how many nights a year will you actually sleep on the boat? Not the nights you can picture. The nights you will book, on the days you were allocated, with the people who will really come.
If the answer is a handful, the sensible boat is smaller than the one you were looking at, because everything above the day-boat threshold is capacity you are carrying for nights that do not happen. If the answer is a dozen or more, the step up pays for itself in nights that are comfortable rather than endured.
This is the part that surprises people, and it is the strongest argument against overbuying. Your allocation follows the size of your share, not the size of the boat. A 10% share of a 6000 and a 10% share of a 4400 both give you a tenth of the year's days on that vessel — the bigger boat costs more to buy into and more to keep, and gives you no extra time on the water.
So the question is not how much boat you can stretch to. It is how much boat you will still be glad of on a grey Tuesday in May when the plan is a coffee run and a couple of hours out of the wind. Share prices across the fleet run from around $19,500 for 10% of a Garnet Offshore 270 up to about $625,000 for 12.5% of a Longreef 90SX, and live pricing for every vessel is on the fleet page rather than in an article that will age.
Sport Yacht. It describes a boat with a low sports bridge and a more raked profile rather than a tall traditional flybridge. The 4400SY through 6000SY in the BSA fleet all share that layout family, at increasing lengths.
No. Days follow your share percentage, not the boat's length. A 10% share is a tenth of the year's allocated days whether the vessel is a 4400 or a 6000. Bigger boats cost more to buy into and more to run, not more to use.
Between four and eight, depending on the share sizes sold. Shares in the fleet come in 10%, 12.5% and 25%, so a boat sold as four quarter shares has four owners and one sold in tenths has more.
Across the fleet's marinas rather than at any single one. The Spit at Mosman holds the largest concentration of BSA boats with 14 vessels, followed by Rushcutters Bay with 8. The fleet page shows exactly which hull is berthed where before you enquire.
