Does the lake you will boat on lend itself to a lot of straight ahead boating, or will you be turning and adjusting course a lot? I hear those larger twin ellipticals turn flat and a little harder than a normal pontoon, or certainly a tritoon. Perhaps a twin elip owner can speak to how accurate that is or is not.
If just doing a lot of straight ahead cruising, maybe its less of an issue which what you go. However, if you will be turning a lot or making a lot of subtle course corrections, maybe worthwhile to go power assist.
I remember a piece of advice I got on this forum back in 2016 when considering our order. I was asking about a lot of things, including helm and seating (I’m only 5‘ 8’, so not very tall), and power assist steering (bad back/neck).
Someone pointed out that everyone often sinks a lot of money into boat options that impact passengers. However, they sometimes shortchange themselves. They suggested if I was going to be the main captain at the helm most of the time, why wouldn’t I invest in my own comfort as over time I will be putting in a lot of time behind the wheel? That advice stuck with me, and I am glad I listened to it!
It did cause me to spend more on my power assist steering, but I have never regreted it. I wouldn’t get a boat without it now. IMHO it is a worthwhile add on. That said, I have a tritoon and not the twin ellipticals.
