what about weldbuilt boats? are they any good?

Very capable - very light and fast

Cross bracing is not ideal - allows some denting between braces - but I really
liked mine - just not as tough as a GD or other hull with longitudinal braces

It will be fin as long as your not running stumps or jumping logs and stuff.

Thank you for the up date. What size is your boats, what size motors, and how fast do they run?

I had a WeldBilt 17x42 with 25gdlt then a 27 gdsd

longtail would do 21mph solo - 18mph with 2 men and gear

27 gdsd would do 29mph solo - 25mph with 2 men and gear - 18mph with 3
35 gdsd - was too much for it - flexed the hull and ran spooky fast and
was unturnable at 35 plus mph - LOL

Boat was old (10 years)- light (.80 gauge 350lbs) - and fast but
slid pretty good in a fast turn due to the square chines.... Bottom
was dented between every rib - but never seemed to affect performance
just looked like heck...

I got it well used at a good price and it was a very capable and enjoyable
hull for the 2 or 3 years I ran it - carried a load very well - square nose
was a bit unforgiving in the timber was about my only negative issue....

Not the same boat, but comparable...
I run a 16'x48'' allweld and push it with a 2005 moded out Mud Buddy. I get 29mph in a few feet of water with no wind.
We beat the SH!T out of it and it holds up fairly well all things considered. It is by no means ideal, and I wiill upgrade to a mud boat hull when i can afford it. It slides (just like all square chine boats IMO) in the turns, and does fine in the mud.
All in all the boat does what I need it to do and holds up fairly well. I did have to have the transom support re-welded (30 min and $60) after a few years of tough trailering.
I got it dirt cheap from a friend so it was the best/only option at the time for me. Not the perfect boat, but gets the job done.

The newer Weldbilts were having a lot of problems with welds breaking. I'm not talking about guys abusing their rigs, I mean guys with outboards running clear water. Don't know if they got the issue fixed or not.

FTR - mine was a true mudboat with slick bottom....

Don't know how the .80 held up as well as it did - but it never leaked
a drop or had any transom issues - although I was scared to leave the
35 GDSD strapped on there - only ran it one weekend - just too much
torque - flexed it pretty bad and only about 2 feet stayed in the water
when you horsed the throttle - hull was only rated for 25 hp though in
all fairness..... Ideal for 23 to 27 hp though....

i have one i run a 25 HP outboard on. every weld in the front 2/3 of the boat broke within the first year. the bottom cracked in 3 places.

The mudmotors will tear the transom apart Have done that!

I bought one this year a 12x36. I put a 6hp Long Tail that I built on it. I put this together with the intention of pulling it into some remote spots we hunt with my 4 wheeler. We got serious stuck last year with the truck trying to get out at night after a walk in hunt. I hope it will allow us to get to spots on the lake easier than walking through the mud. I added an alum. diamond tread floor, 1200 GPH bilge, grab bar and 2-100 watt Explorer Pro Comp lights on a light bar I welded up. I will let you guys know how it works out.
