The Piana 30 is aggressively canvassed for its weight.
Hull Speed
The theoretical displacement-mode speed limit — determined by waterline length, not engine or sail power.
7.2 kts
A displacement hull pushes a bow wave whose speed is limited by the waterline length.
With a waterline of 29.0′, the Piana 30 tops out around 7.2 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √29.0′ LWL = 7.2 kts
Performance Ratios
Racing handicap, sail-carrying power, stability and comfort — and what each one actually tells you about a day on the water.
SA / Displacement
30.1
Performance-oriented — carries a lot of canvas for its weight.

Estimated Speed by Wind
Rough boat speed estimates at different true wind speeds and points of sail — derived from hull speed, SA/D, and displacement, not measured polars.
| Point of Sail | 6 kts TWS | 10 kts TWS | 15 kts TWS | 20 kts TWS |
|---|---|---|---|---|
| Close-hauled40–50° | 3.4 | 4.3 | 4.8 | 5.0 |
| Close Reach60° | 4.1 | 5.2 | 5.8 | 6.0 |
| Beam Reach90° | 5.0 | 6.4 | 7.1 | 7.2 |
| Broad Reach120–135° | 4.6 | 5.9 | 6.6 | 6.8 |
| Run150–180° | 3.7 | 4.7 | 5.3 | 5.5 |
These are simplified estimates based on hull speed (7.2 kts),
SA/D (30.1), and empirical efficiency curves — not instrument-measured
polars. Real-world speed varies with sea state, bottom condition, sail trim, and current.
Speeds in gold approach hull speed;
bold gold means near or at hull speed.
Wind Range & Comfort Envelope
Estimated wind ranges for comfortable sailing on the Piana 30 — based on sail area, ballast, and displacement characteristics.
Ghosting
0–5 kts
Light air, motor-sailing likely. Need patience and a light genoa.
Sweet Spot
5–16 kts
Comfortable under full sail. Best speed-to-comfort ratio.
Time to Reef
16–24 kts
Time to shorten sail. Reef the main, swap to a working jib.
Heavy Weather
24+ kts
Storm conditions. Storm jib or bare poles. Seek shelter if coastal.
