the nacra 5.2 has about 2% more sail than the h16...

but the nacra can be sailed easier without the jib, and removing that is subtracting about 20% of the total sail area...

so in theory i would say the 5.2 is the better solo boat, unless you are beach launching or sailing in shallow waters where the nacra's daggers can be a handful at best and destroy the boat at worst...

so general advise would be to buy the boat in the best condition that you can afford, don't get locked into a wreck that hasn't been sailed for 5 years and has parts missing over a good sailing boat on a good trailer
