Stotesbury 2026: St. Joseph's Prep owns the Schuylkill, Montclair owns the weekend's story

Forty teams across the two Varsity 8+ classes, 1,500 metres on the Schuylkill, and one programme walked off the dock with two Golds. St. Joseph's Prep won the Men's V8+ Friday time trial in 4:21.65, the Men's 2V8+ time trial in 4:29.61, both Saturday semis, and both Saturday Finals. That is the loudest single story of Stotesbury 2026. The quieter one is louder, the longer you look at it.

The quieter story is Montclair. A PSRA programme that sat outside every public Power-10 board on this site going in, Montclair leave Philadelphia with the fastest Women's V8+ Friday time trial (5:04.93), the fastest Women's V8+ Saturday semi (5:36.53), the Women's V8+ Championship gold by 5.67 seconds (5:29.47), and a Men's V8+ silver decided by 0.07 seconds at the finish line. Two boats in the A Final, two podiums, the rare PSRA-Catholic-Schools-and-public-rival sweep most coaches will be asked about for the next ten days.

The model spent the weekend learning what it could from a regatta most of its top-rated US crews chose to skip.

What didn't happen at Stotesbury

Before the boat-by-boat reading, the structural fact. The crews the April Power-10 put at the top of the US Men's V8+ — Greenwich, Norcal, Marin, Kent, PNRA/Mercer, Cincinnati Juniors — did not enter Stotesbury this year. Neither did the April Women's V8+ #1, Winter Park. The entry list was PSRA, WMIRA, VASRA, and NYSSRA — the four leagues for whom the Schuylkill is a bus ride.

That is the regatta describing itself. Stotesbury in 2026 was a regional championship, not a national one, and the rating's response is honest about it. Crews that didn't race lost a small amount of RPI as the April field they had outperformed got recalibrated upward against Stotesbury's actual depth. Crews that did race either gained on the result or held station against an honestly stronger comparison set. Both readings are in the post-Stotesbury rankings dated 17 May on model v0.9.6.

The numbers below are post-Stotesbury. RPI is on the four-digit scale anchored around 1500, the same scale published since launch on April 29. The 90% credible interval is the model's honest statement about how much it does and doesn't know.

Men's V8+

Friday's time trial set the order at the top. St. Joseph's Prep went 4:21.65; Montclair 4:23.32; Whitman 4:24.19 — three crews under 4:25 over 1,500 metres, the rest of the field spread back to 4:34. Saturday morning the semis confirmed the same three names won their heats. Saturday afternoon they were the only three crews under 4:55 in the Final, separated by 2.66 seconds top to bottom.

The 0.07 seconds between Montclair and Whitman at the line is the smallest scoring margin of the weekend in any boat class on the Schuylkill. The model's reading after Stotesbury has Montclair eight tenths of a length ahead in the rating. The photo finish has them effectively level. By the next refresh those two should sit closer to where the camera put them.

St. Joseph's Prep sit at RPI 1868 with a 90% interval running 1829 to 1910 — the second-tightest top-ten interval in the boat class. The model resists pushing them further on a Saturday whose strongest cross-region opponent was a WMIRA crew the Northeast schools have not yet faced. They have closed the interval to Greenwich. They have not closed the gap.

The story underneath: Whitman, one of the only April top-tens to enter, dropped 93 points of RPI on the recalibration. Bronze on the Schuylkill cost them rank against an April body of work the model now reads less generously.

Men's 2V8+

The single most dominant result of Stotesbury weekend. St. Joseph's Prep's 2V8+ went 5:05.80; the next-fastest 2V at the regatta was 9.73 seconds back. That is not a margin a model fits inside a probability interval. It is the kind of margin that tells the rating to widen its own probability range for the SRAA Final and the Henley Royal Princess Elizabeth qualifier.

St. Joe's now sit at RPI 2021 — US #1 in the boat class, ahead of Greenwich (RPI 1976) and the recalibrated NEIRA contenders Deerfield (RPI 1941, down from 2200) and Kent (RPI 1931, down from 2141), both of whom shed more than 200 RPI points without racing as the model recalibrated their April field-strength prior.

Saturday's most-rated trip wire was St. Peters. Second on the day, ten seconds clear of Yorktown, not on the public Power-10 going in. They are not on it yet — Saturday's result alone does not lift a crew with thin cross-region racing into a body-of-work top ten — but the team page reflects the model's reaction. SRAA will be the test.

Women's V8+

Montclair's Women's V8+ won Friday in 5:04.93, won the fastest Saturday semi in 5:36.53, and won the Final by 5.67 seconds. They climbed from outside the public table into the conversation in one weekend.

Two PSRA programmes either side of Mount Saint Joseph tell the rating's other story. MSJ's silver — 0.57 seconds clear of WMIRA's St. Andrews, not to be confused with the Florida St. Andrews RC that sat at #4 in April — pushed them up the table to RPI 1878. The Florida programme, which did not race, dropped to US #7 (RPI 1952) on the same field-strength recalibration that lifted MSJ.

The model's US #1 in the boat class remains Winter Park at RPI 2127. Row America Rye sit at US #2 (RPI 2088) — and here is the regatta's most curious rating move: Row America Rye gained 48 points of RPI without putting a hull in the water. The mechanism is regional. The Mercer Lake and King's Crown fields they beat in April just got more credible against the Stotesbury comparison set, and the model passed the credibility along.

Women's 2V8+

Mount Saint Joseph the Women's 2V8+ winner, after a Women's V8+ silver three hours earlier. Two PSRA medals in two boat classes inside an afternoon, the only programme on the weekend with a top-three V8 and a top-three 2V8 on the same Saturday.

The most consequential rating move in the boat class is at the top, and it didn't happen on the water. Atlanta Junior — the model's pre-Stotesbury public US #1, who did not race at Stotesbury — held US #1 cleanly (RPI 1946). The biggest non-racer movers were Greenwich (▲2 to US #3, RPI 1888), Deerfield (▲3 to US #8, RPI 1814), and Row America Rye (▲2 to US #4, RPI 1879). The Southwest contenders gave most of it back: Marin drop three places to US #6, Newport drop two to US #10.

What the model learned, in three sentences

Stotesbury 2026 was a regional championship in the body of work it produced, and the regional crews who attended either gained rank against teams with thinner cross-region race books or held what the model gave them in April. The most-confident statement the regatta made was the 9.73-second margin in the Men's 2V8+ Final. The most-uncertain statement was the 0.07-second photo between Montclair and Whitman in the Men's V8+ Final.

Ten days from now, the SRAA Youth National Championships put Greenwich, Winter Park, Row America Rye, Atlanta Junior, Cincinnati Juniors, and the rest of the absent April top tens on Lake Mercer against the crews who just owned the Schuylkill. The next reading of the rankings is the one the model has been waiting all spring to write.
