[C38] How to approach an argument with a sailor

[Patrick Harpole]

I sail a Catalina 38 and reached 12 to 14 knots sailing from Benecia to 
Berkeley.  The reason for the speed is an ebb current at 6 knots.
There is no way a displacement vessel can reach greater than their 
calculated hull speed.  When one exceeds hull speed they are unduly 
stressing their rig...which might come down.  What a shame for being stupid.
