TL;DR Part
I'm a senior mechanical engineering student, me and my group are working on a surfboard with a jet engine (kinda like a jet surf?)
we don't know anything about surfboards and wanted your inputs.
The boring long part
So, Mechanical engineering students are required to create something new or improve something that already exists yada yada...
during the brainstorming for ideas, Surfboard with a jet engine sounded fun and stupid. which is rad!

First off, what do you think of the idea as a final project kinda deal?
Is it practical?
uuh.. Is it stupid? should we go through with it?
what should I take into consideration before building the damn thing? scientifically speaking, or any way of speaking

your input will greatly help me in my research. you guys are the experts

and please be brutally honest with me I can take criticism.
Thanks a lot. I'll have more questions coming depending on how this goes.
