>>> The aerotec was genuinely scary, felt very unstable and after a gust of wind lifting me as I jumped over a wave I called it a day. I guess its a boat that you can't really use 1 up<<<
To be honest one up with any air floor SIB, a 25hp and no tiller extension that's what you're going to find.
I wonder if you need to make a steering setup... it would transform your experience...
I'm inflating mine in the garden today to wash it out. I have three gauges... two Zodiac supplied (Bravo I think) and one bought as a Bravo. I will check them all for how they behave and report back.
I say that because I've not used the manual gauge for about 9mths so wouldn't want to mislead you.... as I said these days I just use the Bravo pump with its digital gauge to go a bit over and no longer recheck on the water.
