Kaiser 26 Performance

How the Kaiser 26 performs on the water — racing handicap, sail-carrying power, stability and comfort.

+ Add to Compare

The Kaiser 26 is moderately powered for comfortable coastal cruising, with acceptable motion comfort for coastal passages.

Hull Speed

The theoretical displacement-mode speed limit — determined by waterline length, not engine or sail power.

5.9 kts
A displacement hull pushes a bow wave whose speed is limited by the waterline length. With a waterline of 19.5′, the Kaiser 26 tops out around 5.9 knots in displacement mode — after that, the bow wave outruns the hull and resistance climbs steeply.
1.34 × √19.5′ LWL = 5.9 kts

Performance Ratios

Racing handicap, sail-carrying power, stability and comfort — and what each one actually tells you about a day on the water.

PHRF Rating
269s/nm
Heavy or slow cruiser — all about the journey, not the elapsed time.
SA / Displacement
15.7
Moderate sail power — a capable coastal cruiser, not overpowered.
Ballast / Displacement
43.6%
Stiff enough to carry a big genoa comfortably into moderate breeze.
Displacement / Length
373
Heavy displacement — a slow, steady, seakindly hull.
Comfort Ratio
28.9
Acceptable coastal comfort — fine for weekends, notice the chop offshore.
Capsize Screening
1.71
Below the 2.0 offshore threshold — acceptable for ocean passages.
Hull Speed

S# (Speed Number)

SA/Disp (Calculated)
16.5
Computed from measured I/J/P/E rather than reported sail area.
Pounds/Inch Immersion
546lbs
Weight needed to sink the hull one inch — loading sensitivity.

Motion & Offshore Suitability

Two ratios that matter most when you're planning passages — how the boat feels in a seaway, and whether the hull geometry is suitable for open ocean.

Comfort Ratio
28.9
Acceptable coastal comfort — fine for weekends, notice the chop offshore.
Under 20 — Snappy, racing motion
20–30 — Acceptable coastal
30–40 — Good offshore comfort
Over 40 — Very comfortable offshore
Capsize Screening Formula
1.71
Below the 2.0 offshore threshold — acceptable for ocean passages.
Under 2.0 — Acceptable for offshore
Over 2.0 — Coastal / protected waters

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° 2.3 2.9 3.2 3.3
Close Reach60° 2.7 3.5 3.9 4.0
Beam Reach90° 3.4 4.3 4.8 5.0
Broad Reach120–135° 3.1 3.9 4.4 4.6
Run150–180° 2.5 3.1 3.5 3.7
These are simplified estimates based on hull speed (5.9 kts), SA/D (15.7), 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 Kaiser 26 — based on sail area, ballast, and displacement characteristics.

Ghost

Reef
Heavy
0–7 kts 7–22 kts 22–32 kts 32+ kts
Ghosting
0–7 kts
Light air, motor-sailing likely. Need patience and a light genoa.
Sweet Spot
7–22 kts
Comfortable under full sail. Best speed-to-comfort ratio.
Time to Reef
22–32 kts
Time to shorten sail. Reef the main, swap to a working jib.
Heavy Weather
32+ kts
Storm conditions. Storm jib or bare poles. Seek shelter if coastal.
