Testing a New Performance‑Based Rating System in 2026

More competition, more fun for everyone.

Presented at the 2025 BAMA Annual Meeting

What’s Broken Today

Stagnant Fleet

Only 3–4 boats show up and win repeatedly, which reduces motivation for the rest of the fleet.

Hard for New Racers

New sailors struggle to become competitive because their starting rating does not reflect real performance.

Static Ratings

Ratings stay the same all season, even when a boat consistently sails above or below its handicap.

How the New System Works

Step 1

Start with Base PHRF + DPF

Each boat begins the season with its usual Base PHRF plus a Dynamic Performance Factor (DPF) that will move over time.

  • Existing racers: DPF is based on the average performance index from recent seasons.
  • New racers: DPF starts at 0 and adjusts as results come in.
Step 2

Score Each Race with PI

After every race, each boat gets a Performance Index (PI) based on how its corrected time compares to the winner.

PI = Boat’s Corrected Time ÷ Winner’s Corrected Time

Step 3

Update DPF Over the Season

Over multiple races, each boat’s average PI nudges its DPF up or down within defined limits, keeping the fleet fair and competitive.

Adjusted PHRF = Base PHRF + Dynamic Performance Factor (DPF)

Why This Is Better

More Boats in the Hunt

Ratings react to performance, so more boats have a real shot at a podium over the season.

Fast Learner Protection

New sailors aren’t punished immediately; their rating moves as their results stabilize.

Transparent Math

Simple formulas and clear limits make it easy to see how and why ratings move.

Season‑Long Story

Each boat’s rating history tells a story of improvement and performance across the year.

What Day One Looks Like

Pre‑Season Setup

Compute starting DPFs for returning racers from 2024–2025 data and load the fleet list.

First 2026 Races

Run early‑season races, record finish times, and compute PIs for each boat.

First Adjustments

After a minimum race count, apply the first DPF updates and publish the adjusted ratings.

Questions, Concerns, Ideas?

BAMA will pilot this performance‑based rating system in 2026 with clear documentation, open data, and a feedback loop from the fleet.
