I have a 1983 18' Advantage open bow, BBF, Berk JE, diverter, HTP shoe and rideplate. Rogers design hull, 75 mph with mild power. Likes to walk a tad at speed, but no big deal. Good manners, no surprises...... you'll like it.
Welcome to the forum ncjb dude.
Which Advantage hull are you inquiring about? In general Advantage boats are well designed & built and typically perform in the top of their class. I have an 83, 18' bubble deck. It's a copy of a Rogers 18' Bonneville. I really like the boat, handles chop very well, it's quick, turns well and runs well into the mid 90's on 670hp. This model of hull is very popular with the circle racing guys as well as river/lake hot rodders. Having "bottom work" done is a slippery slope. If done correctly it can be a blessing, if not it can be a lot of work to correct and potentially dangerous. As always, check hull condition and bottom work history thouroghlly. Hope this helps in your quest. Good luck.
looks just like this boat. dave from GT boats help him do the work to the bottom
the boat is very very simillar to a rogers. probally because hary christansen worked for roger wieman back in the day. i wouldnt be suprised if it was rogers old mold. very nice boats wish there were a few more advantages running in comp jet these days
