Sunfish are notorious for getting waterlogged. They can be dried out. Do a Google search on drying out a Sunfish and you will find a lot of good info.
A Sunfish and a Hobie Monocat have vastly different construction methods and materials.
A Sunfish fiberglass, with foam flotation blocks (much like the fiberglass models of Hobie Cats) and is mostly open space on the inside, which allows airflow to gradually dry the flotation foam (once ports are installed).
A Monocat is essentially a foam hull covered with a thin ABS plastic skin. The foam is not only for flotation - it's structural. There is no way to get airflow in/out the hull to allow the foam to dry.
This thread has the dissection photos that show how the hull was constructed: viewtopic.php?f=9&t=37786
Unfortunately, this model (and the Hobie 12 monohull) were doomed from the beginning by this construction method - and precipitated their early demise.
