Thanks your is the same as mine (well within 1/16") and mine was built to be a jet. I guess that answers my question. I took a quick measurement on my center sponson angle in relation to the outer sponsons, and the center sponson is on a .5 degree angle in relation to the outer sponsons. My hull is very straight so i was able to use a short digital protractor to check that. If you have the tools maybe you could check yours.
Thanks for the reply.
