Hi Jeff,
I can't help much comparing the quintrex to savage unfortunately.
I had from new a 2003 quintrex freedom sport Bowrider 5.3 m. 115hp Yamaha, In 2015 we changed to a 2015 Stacer Bowrider 5.7 150 etec.
Comparing those two boats the quintrex was more stable at rest, it was prone to prop ventilation/cavitation whilst doing water sports. The freeboard seemed higher.
The Stacer turns on a dime, rides better but is not quite as stable at rest. It is more sensitive or responsive to the trim settings. Ideally I think trim tabs would suit this boat as it can sit a bit port or starboard whilst underway.
To drive I would take the sportier feel of the Stacer every day it just feels so much better sitting position and all. Just my opinion.
If I was only fishing outside I would think a cabin is the way to go. For general all round use the bow rider is unreal. The half cabins we had every body wanted to sit up the back rather than be closed in.
The bowriders are also good for casting lures and jigs from especially without a Bimini on using it as an open boat. Also very easy to get the anchor ect, we never use the bow cover on the water, it just cuts off half the boat.
I use mine inside and outside in the right conditions. There are plenty of centre consoles and walk around doing the same.
I hope that helps.
