 NO.... The big difference is, 

a seaplane can have 2 types of contact points one which is the usual
gears on ground, which is retractable and well defined on both FDM.
the second which is part of the fuse and auxiliary floats, with JSBSim
we have not any difficulties to define it ( i have a seaplane modelled
with 12 contact points) and makes the aircraft standing correctly.

with Yasim we must find a medium way to get the same effect.
About retractable gears no problems, about contact points on the fuse
big problems .....
