u have answered your own question. Few things i have experienced when wanting easy paddle power
1- yes a big wide board is a good start
2 - the flatter the better
3 - make it heavy, those epoxy big boards are good if you are a strong paddler to start with, they are very light for their size and thats because the poeple who own them want them to be manoverable. If you can try 2 similar boards out, 1 being glass and heavy, and 1 being epoxy, you will notice the difference.
as for early entry against offshore winds and dealing with chop, i would image someone who owns an old mal would realise the benefit to owning a heavy board, nothing destorys chop and deals with offshore winds like an old mal.
for knee paddling you will need width, how much?, will depend on your own coordination
also any chance that old mal is for sale?
