What is the average length & width

[FloridaScaleBoater]

Of a 20 hydro.
Acquired something small & really light. Wondering if it's too small for a .21

Wow, 93 views and no one whats to share the size of a 20 rigger?

Rick, what width are you looking for? Between the sponsons I run 16”, the tub width is 3-3/8”. In your first thread I wasn’t sure if it was for a sport 20 or a rigger.
Thanks John

A competitive 20 hydro is likely around 3-4 lbs depending on construction and tank size. Look at any of the JAE's as the lightest examples.

Hey John, overall width, out side to put side of sponsons.
And length of tub I guess

I don’t have mine on hand to measure
JAE GT is 33 inches long (Tub)
Beam is 20 3/4

Rick, my new .21 boats are 33 inches long, 3.5 inch wide tub, outside sponsons are 21.5 inches but my sponsons are old style and swoopy. Modern hydros all seem to be narrower, longer, and wider footprint than what we raced for 30 years ! My 21.5 inch outside of front sponsons includes almost 1.75 dry inches over the water line.

Currently building a 21 canard and it is 27" long X 4 3/8" wide sponson width is 14"

Rick,

I build my BlackJack at 30-1/2" tub length and a 3" inside width (less than 3-1/2" outside), with an extended strut. My inside sponson width is 12". Some have used longer booms, to as much as 14" inside width. It's really easy to build under 4lbs, with most coming in between 3-1/2 and 3-3/4 lbs. If you get much under 3-1/2 lbs, you'll likely end up on your cowl more than your sponsons, and more time hoping not to get hit than racing.

Thanks. Brad.
