Futura 141 or Ultrasonic
I need a little help in deciding which large board to get for early planing with 8.5 and 9.5 meter Ezzy Freeride sails. I am trying to decide between a Futura 141 and an Ultrasonic. Both would be in the top (most expensive) construction.
I weigh 154 to 160 pounds (about 72 to 75 kilograms) depending the number of bowls of ice cream I eat. I am 5 feet, 8 inches tall (173 cms). I have sailed for over 15 years and am a fairly good sailor, though not great. Still working on planing jibes, though occasionally I make one. I can water start fine, sail upwind with no problem, achieve reasonably competitive speeds, etc. In other words, I am an okay but more or less average experienced sailor.
My sailing is mostly on inland lakes about a mile or so across with chop in 8.5 and 9.5 conditions from 0 inches to 8 inches (up to 20 cms). This past season I sailed the 9.5 nine times and the 8.5 twenty three times. I used a heavy 150 liter freeride board. It planes early, not because it is an early planing design but because it carries a large sail. But I want something that planes even earlier and stays planing longer.
I have other boards for my sails of 7.5 meters and down. I sail about 80 times a season. Most of my sailing is on smaller gear. But I have big gear to maximize time on the water and fun.
My questions are as follows. First, is the Ultrasonic overkill for my size and my sail sizes—that is, is it too large for my weight and my sails of 8.5 and 9.5M? My concern is that it will carry 12 meter sails and that 8.5 and 9.5 are somewhat close to the bottom of its range. Also, people have told me that going larger and larger in board size does not result in even earlier planing for light weights. In fact, some have told me that going larger actually decreases early planing because it takes more energy to move a large thing than to move a small thing. So please enlighten me if you can.
Second, would the Ultrasonic plane significantly earlier than the Futura 141 given the fact that I am a light weight and given the facts that I sail more 8.5 than 9.5 and that my largest sail is only 9.5M? If your answer is yes, how much difference in early planing would there be?
Third, would the Futura, being smaller, be easier to jibe and attain good speeds on?
Of course I appreciate any other insights you can give on the differences between these boards for someone of my weight and ability with sails of 8.5 and 9.5.
