Don't think they own Tracker line John...to the best of my knowledge these are the companies that Brunswick owns building boats.
Brunswick makes Albemarle, Baja, Bayliner, Boston Whaler, Cabo Yachts, Crestliner, HarrisKayot, Hatteras, Laguna, Lowe, Lund, Maxum, Meridian, Palmetto, Princecraft, Sea Boss, Sea Pro, Sea Ray, Sealine, Triton and Trophy.
In my opinion it makes no sense for them to go fiberglass and compete with their own companies..but then again they make Crestliner/Lowe/Lund/Crestliner just to give people many choices to hand over money to one parent corporation.
As for Salpro's comment about price. Go get quotes on Tracker, Crestliner, Princecraft and Lund..with as close to similar models as you can. Ask for the EXACT same options, seat pedestals and seats (Captians chairs can run a Grand alone), motor, kicker and electronics and you might just find that Lund isn't priced any higher than the rest. The Tracker 21WT ends up costing lots more than a 2025 Pro V..heck more than my 2150 Baron as matter of fact.
