RG 65 Design with Freeship – 9

The calculations in heel:

generally is reasonable:

-Volume

0,0008 m³ –> 800 g :  at 20⁰ the draught is 0.03 m, at 30⁰ is 0.027 m, at 40⁰ is 0.020

0,0009 m³ –> 900 g : at 20⁰ the draught is 0.032 m, at 30⁰ is 0.03 m, at 40⁰ is 0.022

0,001 m³ –>  1000 g : at 20⁰ the draught is 0.034 m, at 30⁰ is 0.032 m, at 40⁰ is 0.024

– LCB

The LCB variation is practically tenths of mm, that if is not so wonderful is  reasonable by the rush that I’m  making my first RG 65

– Wetted Area

The wetted area variation is not good, tends to increase significantly , the second RG 65 will be more worked

– Cp

The Cp are with good values increasing with heel which means that increase as velocity increase, what is good.

Well, I’m going to do my first RG 65, who follows me? The Freeship .fbm file is available for anyone, just send me an e-mail .

Cheers
