Looking for Marshrunner Boat Stories

[tlinder]

I have a marshrunner boat,it is about 17 to 18 foot and about 48 across bottom,I traded a 15 foot allweld for it.its been sitting under my carport,I did not realize how heavey it was until after I traded, my 25 merc with 2 people and gear was only running maybe 15 or 20 mph,I was being passed by tugboats,HA! ,the floor feels soft, it is a good riding boat ,im thinking about cutting it down to 12 or 13 foot and making it lighter .my question is,it looks like they have some kind of aluminum pipe in the bottom? could someone clear this up for me. I may also consider trading for 12 foot all welded boat.just boat for boat I keep my trailer and motor thanks
