My dad is giving me his Lakesport aluminum boat when I go home for New Years. It doesn't have carpet so in the future I would like to add some. Is there a particular brand/type that is better than others as far as durability, texture, resistance to hooks getting snagged beyond hope? TIA for any responses.

For the average tin can, I just go to home depot and get the gray stuff they sell on the bulk roll.

To help from getting snagged, you would have to use a cut pile instead of the loop pile, the stuff HD sells I a loop pile.

They pretty much go by weight in grade.  The 16oz is probably a heavy as I would want in a jon.  20oz used to be the standard for plush carpet in the bigger glass boats, and then they went to 26oz.

If you have a boat that has a flush deck and lids, if you go to a heavier, more plush carpet, it usually binds the lids and you have to shave it between the lids.

As for the best place to get it, of the difference in quality between them, don't know.

Take a look at bass boat seats.

i got carpet for my last boat and will go here next time I need carpet.
