Blueprinting hulls
 

Looking to get more info on hull blueprinting and balancing
is there anyone good in the area?What kind of increased
performance can I expect from boat?

Give Jack a call at Hydra powerboats. Toms River 732 506 7701

he might be able to help you out. as far as performance increase, Ive heard dramatic increases as much as 15 mph gain, to as little as 3 mph. depends on your hull

Dont count on a 15 mph increase.

I agree. thats on the xtreme side of the spectrum. but it did happen. Are you familiar with the Avanti 33. That boat apparently has a bad ass hook in the hull. A friend picked up that much speed after shaving the hull. And yes, I'de say 2 to 4 mph is more likely. Especially on a Hustler, if thats what your running.

Is hull blueprinting a plus more for older hulls ? If so what MPH increase should be expected if done on a 28 ft. Cig. ?

We do every hull (as a matter of fact, we just flipped the red boat over this past week) and the boats simply handle better. The speed increase is minimal, at least on our boats.

Make sure it is done correctly or you are wasting time and money.

What would the cost be for a 26 footer V hull ?

or for a 19 foot V?

BRUCE SEROFF- the hull had enough hook for 15 mph!!! wow!! Must have been really bad!

HyperBaja...

yup, Im told Avanti has had bad hooks in their older boats.

this one, was a early 90's model.

i had mine done on my 28 scarab when i was getting some repair on bottom. they straighten the bottom and sharpen all the edges, it slowed down. even went up in power at same time . the guy might have not know what he was doing?.i know that the motor was pulling the stringer on left hand side making a hook on the botton on that side. because it pulled the stringer and was cracking the botton. i guess it wasent made for that much power?

We just took the hook out of a 1998 25' outlaw boat picked up 6 mph on the customers GPS, We charged him 2500.00 to do the last 5' of the boat , He was so happy with the increase he paid in good old green cash!!! where putting a Pro chager on it now ! Where hoping the lake opens back up so we can test again.

I have a 1978 Martini that was moulded with a hook of about .562" measured over 4'. After I blueprinted the bottom I was finally able to "free" the hull from the water and really light it up!

P.S. I've logged many hours refinishing boats and especially doing one-off customizations. I'd be happy to give you any advice if you would like. Just drop me an e-mail.

Thats what is happening,the outer port side stringer is cracking,
to the point when I put boat back on trailer water runs out for a
few days after.what do you think?

sounds like a much bigger problem than just needing the boat blueprinted. :(

I guess this sounds a little stupid to you guys who know all of this stuff, but I'm not famaliar with hull blueprinting. Does it involve actually sanding the gel off to some degree and adding gel elsewhere to attain as smooth a surface as posiible? Please explain so I might be a little less ignorant in the future. Thanks :o

it depends on the hull, but when you flip a boat over and use a straight edge along the botton there are high and low spots not seen as well by the eye. filling and sanding until area is true, chines made sharp. there can be a lot of sanding required.

A lot of sanding... like weeks and weeks worth. Then respray gel and buff for a few days.

Never had this done, but I've heard that on some boats. like others stated, it can hurt, more than help you. One guy in the Michigan area had his 38 scarab done, and said the handling sucked afterwards.

I'm not saying it's all bad...........I guess like anything else, it's in the hands of the PERSON, not the company doing it. Just do a little homework. Like others illuded to, it's different for all boats.

If I was ever to do this, I'd see if I could find someone with the same boat & get their input.

it was my avanti that picked up 15 mph and not only from the bottom put also going from 365 hp to 725 hp. with the increase in hp the boat ran the same speed as the 454 until the bottom was done.

I put lots of HP in my '77 Martini and basicly got lousy handling and practically no more speed. Then flipped boat, transom notched, and blueptinted (took all hook out) the hull riased "X" dimension and went from high 50's to low 80's with literally "hands-off" steering in the high 70's with stock steering. Don't worry guys, at that kind of speed a good hyd. system will go on before the ice is off even if there seems to be no wear or strain. --- Jer

Besides jack at hydra powerboats,does anyone know of a good
gel coat,surface repair person,at Jersey shore area?
