How to build a Subwing

[lordoftweedhead]

Hi guys, these are those bits of plywood you tow behind the boat and can dive with.
They really are fun to have, especially for those days your just chilling with some friends out on the water, combining tubing with diving and not very hard to make.
Finally finished the build video - enjoy

How to Build a SUBWING, plus the rig in action

 

[John B Griffith Jr]

So is there a fairly narrow range of speeds that it shows peak performance in; i,e...do I have to have a fast "hole shot", or slow and steady acceleration?

Hi John; The best towing speed was estimated at 2 knots - thats about 4km/hr (twice a slow freestyle swimming speed), we you dive the drag becomes so much more and hence you slow down, the boatie could compensate for this but he would have to be very good.
Its a challenge for the boatie to keep a consistent speed and keep the wingers over the reefs, but that's all part of the fun too.

In regards to the range of speeds; I think you can go as slow or fast as you want from the 2knot speed - but the faster the more strain you put on your neck when you try and lift your head up watching where you are going, I'd say maybe only 4knots and its too much, but keep your head down and who knows how fast you could go.

I would suggest a slow acceleration so you dont tear the subwing out of the persons grasp, but ofcourse once you get going, fast accelerations to keep the speed constant would be best.

Thanks for your Question
