Taylor-Gertler Series - Residuary Resistance

Residuary-resistance coefficient from the Taylor-Gertler systematic series - mid-20th-century database still used for concept-stage powering.

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.
