Most entry-level boats are absolute garbage...thin hulls, poor layups, tons of voids, rot easily due to bad build quality and materials, etc.
That being said, as a marine tech/surveyor, Sea Ray (especially 2010 onward) may be my least favorite brand to work on because of how they cram in systems and components with service as an afterthought. No one else does it worse...Sea Ray's production volume dictates an assembly-line-esque procedure, but this means owning the boat, which is modular like a modern car, can be a nightmare when repairs are needed. It's not that they are poor quality, but rather simply an ergonomic nightmare.
My advice would be to look for an (10-15 year old) older, decent sized (21-24'), quality boat from a quality manufacturer like Formula, Cobalt, Chaparral, Bryant, as well as Regal, Monterey, Cruisers, and Four Winns. Some other brands like Robalo, Scout, Cobra, Pro-line, and many others make a decent product too. A 17'-19' boats is TINY and a bowrider can swamp easily, even on a lake. As a general rule, I'd stay away from Brunswick brands (Bayliner, Sea Ray), as well as Glastron, Crownline, Tahoe, Wellcraft, and other cheap boats. If you crawl around these brands or try working on them, their layups, upholstery, and electrical systems are laughable compared to decent to good brands.
My 28 year old Chaparral has zero rot...why? It used XL-10 pressure-treated marine plywood in its transom, decks, stringers, and bulkheads. It also used it in cockpit side panels in addition to plastic seat bases. While the actual build quality leaves a lot to be desired, the high-end materials have kept it like new for this long with good, non-abusive owners. Cheap boats don't use good materials and also have poorer workmanship generally. I have never seen a Chaparral with the XL-10 (1993-1994 for transoms, 1995-2000 for everything) wood rot completely stern to bow like many of the boats on here. Grady White, Formula, and other high-end brands use or have used similar products as well, especially post-2000. Even better are composite alternatives like Coosa. Owning a cheap, non-restored boat and trying to use it in anything but calm water is likely misery.
