I want some sort of stable floating pond boat that can glide over to slop so I can punch mats all day.  It needs to be transportable in a pickup 5 1/2 full-size short bed.  I was eyeing the pond prowler plastic pontoons but found this locally.  It's a "molly boat".  It's rated for 700 lbs of  capacity vs the 512 of the pond prowler.  It is 70 inches wide and too wide to fit in my bed.  I have the idea to cut it in half length ways and install larger bar stock over the cuts to make a bolt on coupling.  Some sort of folding plywood deck and is maybe U bolted to the cross bars.  A single tall pedestal seat or back or front bar I can lean onto for standing support in place of a seat.  Wall mount type rod holders mounted to the pontoons for rod holders. 

 

The idea is to transport it to a pond then assemble.  This seem spound?  Is the fact that it has 200lbs more capacity than the pond prowler and indication as to how stable it will be?  

Oops wrong board 

that looks like a blast!!

 

I dont think I would make it modular.  use new bar stock to make it narrower.   maybe add some modification to attach wheels so you can tip it up and the wheels contact the ground and roll away.?

Although stable, I can see a problem with propulsion.  Pedals will wrap up grass and no place to mount a trolling motor and battery.  You could fab something up but remember to make is so you can get to the tm to clear weeds and a place to mount your battery.  That style is not well suited to rowing if you have to.
