How fast is a 28 Skater with twin 300xs's?

Check out the OB Skater thread here on OSO. I have a 2013 28 with my new Dewald props, just made 113.

Speed really depends on the set up, weight on board and conditions. You will hear a wide range of speeds some are top end numbers but not achieved with everyday load and conditions. I good range would be from 108 to 114 or so in ideal conditions (temp/humidity) and weight on board.
