Vago as a first boat?

Hi.
I know another boat question from me but this time its diferent.!

My dad has been on the saftet boats for 2 years and now he wants to get into the sailing game (god help us all) not really im sure he'll do fine.

He has had a few lessons in a Club topaz but found it to flat and to close to the water for his liking and to small.

I was thinking the Vago with the Dacron S rig sail.

Could the S rig be:

A good 1st time boat to teach him to sail for the first time as a hiking dinghy (while reefed I assume)

Be fast and exiting when he gains confidence.

Be powerful enough to sail singlehanded by a 60KG sailor on the Wire
(reefed again unless light)

Be powerful enough to sail double handed with one on the wire.
(combined crew weight of 115 KG) or is the XD sail needed?

anyway thanks for any advise on the vago or alternatives?

Must be made of "nasty plastic" so its easy to maintain or simular
