The mid-late 70's Bahner bottoms were similar to the Rogers, if anyone is interested in one i have a buddy that wants to get rid of one that is in pretty good shape out of San Diego area.
My neighbor kid is restoring one right now, so far its capped, with all new wood throughout ,bottom is next on the list and will eventualy get a bit-o-shine on her!
I like these boats, they seem to handle power along with a decent ride for an 18' jet boat! IMO
They are very similar but from what I can remember the transom is a bit wider and rounded on the some of the Rogers and the Bahners are mostly square if that makes sense.
That is the only difference, but the entire bottom measures the same, but the chine north is where the difference is it think. from what i measured, the length of the bottom, width and heighth of the strakes are same width of the boat...same, i could not see any difference where there might be change, other than the angle of the transom i did not check.
I know the dash on my 18' Bonneville was set further back then the Bahner, so im guessing it may throw weight further forward when on the water then in a rogers where the weight would be set back closer to the engine?
???Im getting dizzy and i tried not to run mine in too rough water anyway! lol
What year are you talking about?...the earlier ones had a similar barrel back design as the rogers did, but very different, those were the ones with the Rogers bottom, and the later ones are splitting image of the Eliminator 18' Bubbledeck, not to mention the Bahner 21' Sport cruiser was identical to Eliminators 21' cruiser, makes me wonder if this was a early DCB kinda deal???
Bahner had 2 different bottoms on 18' boats that they had. At least it's 2 boats that people consider to be 18'ers. One of the bottoms was based on the Rogers and the other was based on a Southwind which had a Delta pad.
I have the Roger's bottom on my '84-
whereas squirt has the Southwind bottom on his 78 (I think it's a 78)
Tracy, I think you have the Southwind bottom on yours?
Even though mine is classified as an 18, it's really only 17'9" whereas squirt's is 18'6", I believe.
