Taylor-Gertler Series - Residuary Resistance
Residuary-resistance coefficient from the Taylor-Gertler systematic series - mid-20th-century database still used for concept-stage powering.
Residuary C_R
0.00110 -
Formula, assumptions, and limits
$$C_R = f(C_B, F_n)$$
Modern tools (Holtrop-Mennen, CFD) preferred. Taylor-Gertler useful for rough powering estimate where no hull-form data exists. Series 64 covers V-bottom planing hulls.
