Just got back from the pond where I met Mike Nass and went for a rip/tear in the 18 ntv. Mikes accomplishments in f-1 tunnel and his complete attention to detail along with the professionals he has working along side of him are very very noticeable in his new venture in building hi performance tunnel boats. Although the hull is largely based on the stv rr, the subtle styling improvements enhance the river rocket very nicely. I would think Roark would be pleased that HNR is keeping safety at his customers best intrest as only the best materials are used when building these boats. Because of his professionalism I'm sure Haulin Nass Raceboats will have much success in years to come. So if any one is intrested in my charger stv it is for sale complete on trailer less engine.
