Blueprinting or tuning a mono hull?

[jester_s1]

I've seen very clearly the benefits of getting sponsons flat and trailing edges sharp on catamarans, so is there any benefit to doing it on a mono hull? I realize that a mono is a much simpler design, but I'm curious if at least making a sharp trailing edge and eliminating any suction from concave surfaces is helpful at all.

Absolutely!

+1 Hell YES! I have a 40" mono and from factory Port side was hooked (pulled inside of hull) and Starboard side was a rocker (pushed outside) giving it a place to pivot in a right hand turn. As soon as I took my sanding block to the Starboard side, it cornered 100% better and no wild spin outs etc...
Sharp trailing edges are mucho importante !

Filled the hooks/concave in my 45" sniper and was able to remove the trim tabs completely.

Do you guys have any tips for blueprinting? What materials to use, what grit sandpaper, etc? I picked up some "White Putty by Squadron Tools" and various grit sandpaper. What else do I need?

POST #7, I like the Marine RX by West Marine, it cures very strong and is very sticky when you apply. I have used Bondo and the Squadron Tools Putty as well. have to say that I like the West Marine the best.
It really makes a difference in terms of your boat's ride quality. I use something around 100 grit ( 120) to roughen up the area to be filled, once cured i use a flat sand paper block to true it, I like to use 220 grit and move to 400, 600, etc. I prime it after wards so I use 800 to 1000 grit to wed sand the primer.
You must wait for the number of hours that is required for the Marine RX to fully cure.

Since the adhesive strip sand paper that comes with these packages tend to run out, I have resorted to use regular sand paper cut to that size and I spray 3M Super77 on the back of the sand paper and adhere to the aluminum block. The only draw back is when you change the sand paper, you must rinse it under hot water and peel it away and use a solvent to take the residual glue off.
