WW says:

Insulation under the floor is not often fitted- mainly as most boats don't need it, and also that it further reduces the available headroom.
If you do add insulation, it is imperative that the material is non-absorbant (polystyrene/Thinsulate, etc)- however, the difference felt (especially if you have 18mm floor boards, beofre carpeting/wooden flooring) will be minimal.
Good underfloor ventilation is far more important- adding insulation can sometimes reduce the amount of circulation, and could lead to condensation not being able to evaporate and be removed.
