    Again, I don't know anything about liners except what I am reading and certainly don't know how Tige, Nautique etc do them or if they are even the same kind of "liner" I have been reading about.

    So..if anyone has any first hand knowledge of what makes a liner boat different than a non-liner boat that would be great.

    From where I sit right now, liners look like a slick way to ease construction of the boat (in other words increase profit margins) at the expense of the quality of the product. If I'm wrong in this, please educate me otherwise.
    Sorry to drag up an old thread, but I have been curious about some of the same things as Bakes so I've been doing some homework and here is what I've found.
    Going to reserve judgment on better/inherently weaker/how Tige is implementing liners into construction as I've not talked to anyone in the know about liners there.

    From what I've found out a liner is basically a third piece that gets dropped in between the hull and the top deck. So instead of a top piece(the deck) and a bottom piece(hull) there is now a third layer sandwiched in between. Again this is just my understanding. The advantage being this third piece can incorporate all the structure and can have areas tooled into it for things like a tray to hold a subfloor bag. Battery holder areas. Basically anything a manufacturer wants without having to build it all into the hull mold.
    The liner when applied correctly is fully molecularly bonded to the hull and usually foam will be put in between hull and liner. Downside being if liner isnt installed correctly and it start coming unbonded from its other pieces it can potentially be in an area with zero visual access or physical access. So the only way to really tell is as things like gel cracks show up, hatches all of a sudden quite lining up, hardware working itself out, boat generally starting to change shape on own.
    This is just stuff I have gleaned from digging around and sending some email. Hopefully I can find out more in the near future and someone with more knowledge can chime in.
    If I had to guess the liners will be built in house by Tige in their own separate molds, but I did find where some manufactures outsource their liner construction and simply drop them into the hull during construction.

    Again some of this could be totally false, just what I've surmised about "liners". Not a bad thing if done right.

    The liners from Tige are really to incorporate the full subfloor ballast premise across the entire line. I personally think that they add an element of strength and organization to the boat. Wiring, plumbing, ballast etc all has a purpose now, locations are the same and installation of these parts are faster which frees up more time for QC, glass and Gel. I think its a win-
