I think the guys name is Bob that owns captains models . I spoke with him awhile back about some of the boats ( I wanted one until I found out the price tag on them ! ) he said he builds most of the boats for people who own the real thing and want a mini model !! For 7,000.00 you can get the viking without the tuna tower , outriggers , and r/c electronics and motors was the price he told me if I remember right . Oh well ......I will stick with my Donzi's ....at least I can say I built it !!!!!!!! I aam running the dumas 3 blade prop , the one dumas says to use .
