I do not own one but have driven the Conquest in very rough Havasu chop and it was fine. Took no water over the front, ran about 65-70 right across the top of the chop and was very stable.
I almost bought one but wanted a cuddy, and a deeper boat for the kids.
Have several friends that have Daytonas and Deck boats and the only time they are not fun is in real high wind driven swells, but are awesome, stable boats for everyday Havasu chop.
Good luck!!!
