Hello,

Can anyone tell me the difference of content between those two book? I'm concidering bying one, but two is bit expensive...

Aero-Hydrodynamics of Sailing
Sail Performance: Techniques to Maximise Sail Power

Is one more theoritical and one more applied? One more science oriented and the other tips to go faster while sailing?

Thanks for your help

[jehardiman]

Are you a sailor/sailmaker or an engineer/designer?

While they both discuss the theory, sail performance is more focused on the rig and sails, while aero-hydrodynamics is the whole package. So Sail Performance for the sailor/sailmaker who is going to be using, not necessarly designing, rigs; Aero-hydronamics for the Naval Architect/designer.

thanks for your answer.

I'm actually working as a sail designer and had actually studied hydrodynamic and naval architecture. I'd like to get all the aero part right in my head.
So for the sail designing part if I get your rigth the hydro-aero is better.

seaworthiness and hydrodynamics read, i am planning going TU delft to read there sail performance they dont lent out in the library, sailmaking eh?
good book worth the trip or buy first out of a long shortlist? no customer reviews jehardiman so if you can elaborate a little more on amazons product desciption thanx

Product Description
Sail Performance, based on C A Marchaj's classic Sailing Theory & Practice, has established itself as the standard work on the subject and is now acclaimed as a milestone in sailing literature. From wind tunnel tests which he has conducted, Tony Marchaj describes how the factors of wind speed, sail area, sail shape, sail setting, the hull, angle of heel, wind gradient and steadiness of the wind all affect sail power, and why certain rigs are superior in power and efficiency to others. Sail Performance is a major work which is acclaimed for its analysis of the factors that contribute to an efficient sailing rig.

Another book of interest for the sail designer might be; The Art And Science of Sails by Tom WHidden and Michael Levitt. This book is not as academic as the Marchaj books but it has a wealth of information and conceptual text. ISBN 0-312-04417-8
