lined boats vs rolled edge
A lined boat would have a two piece hull, the bottom hull and a cap, as most bass boats. A rolled edge would have a bottom hull formed around the mold making the top edge rolled, then they place a floor/ deck inside the hull.
A lined hull would be more finished on the deck side and could be more easily cleaned, but a rolled hull could be more easily repaired.
The liner type hulls usually weigh more, but some are vacuumed infused meaning they vacuum the excess resin out of the hull while applying the fiberglass during fabrication. This can add strength and reduce weight.
The performance depends on weight, hull design, etc....
hope this helps
