Re: Vintage Alumacraft or Crestliner?
1959 Crestliner Catalog
Try there. The Crestliner may have heavier aluminum, may not. Larson built them, and the company has changed hands many times since. My Voyager had a pad for a tiller motor, but was not very useful. Do you really like your boat? The Crestliner will be simple and sturdy

.
My AC so far has been fine. It's my first tin but seventh boat. Takes a little getting use to not towing 4000 lbs. and of course the rougher light small boat ride. Stable and 35 mph is nice. It's a nice experience being closer/in contact with the water again. My last three boats were a 22.5' Regal, 28' Custom built tritoon, and a 24' Caravelle Invader. It's made well and I'm a sucker for vintage things. A little awkward moving from bench to bench and storage is what it is.
The things that draws me toward the Crestliner is the additional length, and the clear deck area that the rear benches can be stowed or positioned in different locations.
I'm torn. Trying to talk my better half into letting me purchase it and then run them both in the spring before deciding which to keep. Still getting "that look" though so it may not happen that way.
57, was you tiller pad on the rear transom? Could a person even reach a tiller motor to operate one from the deck? Looks like the motors are set back pretty far from the deck area. The Crest has a trolling plate on the 65 Merc so I guess a guy could do without a tiller but again being a sucker for vintage I hate to not use my little Zephyr.
As far as value, can anyone speak for which boat is worth more or more desirable on the vintage market assuming they are in equal condition?
