A 20 ft Youngblood is a nice tunnel.If your uncle had one befor that was not a pickel fork it was probely a 19 ft gullwing design another nice boat.I think the 18foot Youngblood tunnel is faster than the 20 ft.I am sure he will be happy with it.Got some pics of it?Young Blood was the originator of this hull also.Good luck with it.Jake
