Another useful 'number' is the pounds per inch immersion (pounds added to the 'cargo' to sink the boat a further inch into the water) which neither designer provides.

My apology to OneOcean (Vaclav) - the 'Sinkage' number is right there in the data.

That number is usually posted with a 'load' number, since as the boat sinks further into the water the 'sinkage' number will change unless the boat has vertical sides.

Here's an example of useful kayak data (Mariner Max data frommarinerkayaks.com)

Specifics:

Length: 17’ 0"
Beam: 23.5"
Cockpit size (inside): 32.5" x 15"
Depth at front of cockpit: 11.5"
Depth at rear of cockpit: 10"
Center of Buoyancy: 55%
Volume (filled with water): 14.3 cu.ft. (107 gal.)
Volume (Nautilus program): Sea Kayaker uses Nautilus (all the volume inside the shape) 15.1 cu.ft. (113 gal.)

Hydrostatics with 150 lbs. added:

Waterline length: 14’ 6.5"
Waterline beam: 21.0"
Draft: 3.7"
Prismatic Coefficient: 0.50
Midship Coefficient: 0.79
Volumetric Coefficient: 0.00101
Wetted Surface in sq. ft: 18.83
Lbs./inch immersion: 83.2

Hydrostatics with 250 lbs. added:

Waterline length: 15’-0"
Waterline beam: 22.1"
Draft: 4.9"
Prismatic Coefficient: 0.52
Midship Coefficient: 0.80
Volumetric Coefficient: 0.00138
Wetted Surface in sq. ft: 21.68
Lbs./inch immersion: 93.7
