Boat hull fairing

I have linesplan of hull and i finished the modelling by using loft command.But because as per my understanding, linesplan are not exact, so model not coming smooth.
I find always hard to optimise fairing of hull by manipulating points.
Can anybody suggest me or share what you do for hull fairing.
I am attaching my photo of modelled hull.(Which looks ugly forsure)
