It's the same split engine room layout which has its plusses and minuses. The negative is the additional noise and heat that is thrown into the staterooms because of this. Originally, these yachts were never fitted with an adequate engine room blower system, which it needs to have retrofitted to help evacuate engine heat more rapidly, especially in the tropics. The bridge deck area is huge, and you'll find a wide variety of modifications and additions in this area. In fact, these boats are so prone to extensive remodeling that it would be hard to find one that is anywhere near original design.
Interiors tend to range from sumptuous to outrageously tacky.
The hull construction is balsa cored above the water line and solid glass below. And, as you probably know, these yachts are prone to blistering. Decks are glassed to the hulls and are also balsa cored, which provides the possibility that improperly attached hardware has caused water leaks into the core. Another weakness are the aluminum window frames, which were originally anodized but may have been painted. These frames are good at accumulating salt in the slide channels that over time may result in corrosion holes that leak water into the interior.
