Small boats and polly?

Postby Planeguy » Tue Apr 05, 2016 8:23 am

I came across a Dragonfly with stock power. From posts I have read and videos I have watched they seem to run fairly good in the stock configuration but this one has polly on the bottom and the sides so I am wondering what that would do to a small boat that many would consider under-powered. Would the extra weight be detrimental to an 11 ft 45 hp boat?

If it's priced right buy it. Someone will want it regardless if it runs dry or not.

Sandy river running similar to what a person would expect at Thunder on the Loup.

Purpose: Fish and chase down ducks and/or deer that fall in the river. Occasionally carry a passenger and just cruise the river. Economical to run and maintain is a higher priority than running dry.

My mini has poly on bottom and is 12'X5'. Runs pretty good with 65hp on it.

Why not just use quickslick? The stuff is great and I would think on a small boat it would save a lot of weight compared to poly?

That was my thought but I don't how much polly weighs, how thick it is on the boat or whether or not the pros outweigh the cons on a small boat like that. I saw the boat listed on the St Louis, MO craigslist and wondered about it.

Quickslick does increase speed in my opinion and helps protect the hull. Pretty easy to apply!

I heard they make 1/4" poly. :dontknow:

Also, on an average hull (12'x7'), how many holes need to be drilled to attach poly :?:

Thanks :usa:

I worried about the 1/4" poly after you counter sink your bolts. I was told that there is special bolts that limits the amount of poly you have to counter sink.

I searched for rivet and screw spacing for polly and came up with this thread:

viewtopic.php?f=57&t=17423&hilit=screw+spacing

About the 3rd or 4th post gave general spacing info. The number of holes could be computed from once a person knows how much area the polly will cover.

order your screws online I ordered my hardware from McMasterCarr. Cheap and fast delivery I remember 6x6 and maybe one every 2 inches on the edge. Also remember it needs to be warm when applied. UHMW expands allot to. Put it on warm and pull tight when cooled.

You could also check Albanycountyfastners.com they were the cheapest we could find when we put polly on. They have a lot of 10%-15% discounts if you sign up your e-mail at their sight then they are e-mailed to you as they have them.
Good luck

I had a 12x8 Panther with a 4.3 DD Chevy. It would run dry just enough to get stuck. I am in OK and you definitely need poly here for the rocks even if you don't run dry. I think it depends on where and how you run.

My primary concern is about performance of a small boat when adding weight it wasn't powered to carry and whether or not the slickness of the polly would make up for it. No rocks where it would run. Just water and sand with occasional pea gravel. Conditions like these in the link and shallower:

The river looks higher than normal to me in the pictures at the top of the page.

I'm running 1/4" poly on my 15'4 dragonfly. I've ran over some nasty stuff and it is holding up great.
