I'd choose the Nortech first and the OL 2nd and it's not because one is faster than the other or brand loyalty.
1. 43 Nortech, lots of room in the cabin, wide beam, does really well in the rough, good speed for power, size and weight. Solid construction without all the light weight coring mumbo jumbo...
2. 42 OL Legacy, wouldn't want the Epoxy though, good cabin space, superior construction/rigging and attention to detail.
If all I wanted was speed, I'd get a cat.
