Laveycraft bottom design - looking for detailed description
 

Hi guys,

I cannot seem to find but one boat test on the internet on a Laveycraft.

I am looking for a discussion of the Laveycraft bottom design. In particular, I am interested to know about the 29 and the 32 Nuera.

How many steps? What was the intention when designing the bottom? When was it designed? How does the stability of the Laveycraft at 100mph stack up against other manufacturers who specifically designed their bottoms for 100+ mph stability?

Looks like they've got an excellent product but I can't find their marketing anywhere.

The NuEra line was designed by Great American Concepts. I'm not sure when exactly it was designed... The 2750, 29, and 32 all share the exact same bottom design but obviously in different lengths.
They all have 2 steps which are deep and "serpentine" shaped. The strakes stagger after each step, this gives different amount of lift depending on which pad it is running on. It has a 24 degree bottom with a slightly steeper entry to help cut through rough water. There is no rocker or hook in the bottoms and with the size, amount, and placement of the strakes it allows the boat to run very flat and neutral which requires very little to no positive drive trim.
The NuEra bottom was originally designed to be very efficient and fast with minimal power. So when big power was added it wasn't as stable as other manufactures... But about 4 years ago Laveycraft made a couple minor changes to the bottom which improved the design. Now they have zero lean, chine walking, or porpoise. Even with big power.

This is the only picture I have to where you can see the whole bottom. Hard to see the shape of the steps and staggering strakes... It is a 29 NuEra btw.

what yr exactly did they make the changes to the bottom jr?

also what did you do for the change? Move strakes or lenthen them or both ?

Changes were made in late 2007.

Some of the strakes had lip strakes, all were removed except the very front ones... A couple strakes were removed and/or shaved down in size...

Hey Jr,
Is anyone working at the shop. I've emailed, called and left a message regarding the 24 Nuera with no reponse...
Maybe they're just real busy :)

Thank you for that information.

Can you please briefly discuss any big twin power setups Lavey has put in the 29 or the 32 that took the boats over 100 mph?

I had a 29 with two 500efi's that had prochargers. - I never ran it hard with that set-up (bought it that way) But the owner who had it built for him said is was a smooth and predictable 100mph boat. I took the prochargers off and I loved running the boat - very low 90's.
Great in the rough water - with the twins it was very well balanced and flew level without chasing set-up.
Miss that boat.

Been in a 29 single app. and that was a very well balanced boat. The twin big blocks was not stern heavy in the 29 - just asking?

Why is a 29 single with full cabin hard to find? ( not many made ?). I have only seen 2 in the past 1.5 years - one in person, 2000 year model that was at Lavey in March but just sold so I missed that one and the other Dominator 8 had a 2002 year model - that one look somewhat rough in the pics - did not see it in person.

I owned the first 29 ever built - miss that one as well..

The twin 29 sat lower in the water but when it was on plane or "flying" it was level. For the size - in the rough I wouldn't want to be in anything but.

I think Lavey has made plenty of the closed 29's... but I too don't see them for sale much. When the 2750 was introduced - it took the 29's momentum in sales..

Call Lavey - they probably know customers who are thinking of selling... bet they can hook you up with names and phone numbers of possible boats.

Lavey 29 had a (oddly enough) a 29 with a sweet Eickert 850 in it just under 100mph rig- and there was a guy prowling Havasu with a 29 & a teague 1000 - this guy annihilated everything I saw him run against.

There was also a 20 with twin 600 sci's that went for like 90K - an awesome deal.

They are out there. but guys seem to be hanging onto them.

My 2750 runs high 90's with a Whippled HP500 and AFR Heads and a blue-printed bottom. Flat and smooth and should run 100 on the salt. It is for sale.

Thanks for the info. I have been to Lavey as they know what I'm looking for. There is a ton of 2750 's for sale but again more mid cabins than full cabins.

No offense but the 2750 would be too small plus low freeboard, I would have to crawl around in it to make sure - just looks small even in pics.

Really never seen a Lavey east of AZ. Just one 29 mid cabin in TX that I know of. I really do not even care if it has a motor in it nor outdrive. I would rather do my own set up if the hull is 100% & priced right.

Mine is a closed deck with seating for 4 under the deck with a ton of storage space there also. You are aware that the 2750 was Lavey's offshore race boat, right? It also won a ton of those races. I also do not think that it is considered a low freeboard boat. It is 28 1/2 feet long, not a small boat.

How much are you asking for your boat? I remember talking with you about it a couple years back and I know you put a lot of time and money in it to make it run perfect. Would be a sweet boat.

Sorry for the late replies everyone. I'm on a family vacation and don't get much service...

Nordicflame- yes there are people working at the shop. Mon-Sat, 9am-4pm... I'm not sure as to why nobody has gotten back to you... What exactly are you wondering about the 24?

348SStb- there has only been one 29 with big power twin setup... It had twin Merc 600's. I don't remember the gear ratios or props... It wasn't set up for pure top speed, more so all around boating. But we did test it to 110mph and it was solid.
As for the 32, there has been one with twin Merc 600's that ran low 100's and two with twin TCM800's. The 800 boats were also set up with all around performance. They had 1.36 gear ratio turning Merc 33pitch maximus spinning out. Top speed was 115 but it will push you back into your seat pretty hard! Something like 0-105mph in 20 seconds...

I spoke with Jeff last week.
Thanks, Dave

Lavey Jr. Removing some strakes and removing the lip strakes did this keep more hull planted in the water thru out giving more stability. Anything change then on the top speed side of things?

To look at the 2 large depth steps in the bottom you would think that hard cornering might cause problems? How do you keep your bottom design / boat from doing that?

I have been in a 2004 single motor 29 and it does seem to ride on the very top of the water. Very smooth, balanced, stable & handled the rough very well but we did not do any hard turns. Just asking - good info here.
Thanks for your info & time.

It is a perfect boat for someone. Great ride at any speed, fast or slow(wake boarding or skiing) it works great. The boat is not cheap as it is not a fire sale. Please PM or E mail me for my price. [email protected] I just posted a PM to you.

BUP:

by removing some strake, especially the lip strakes, it does allow the boat to have less lift and have more hull in the water. By doing this we actually did not lose any top speed, actually gained speed. This is so because the hull efficiency is still there and it is more stable therefore the boat won't get unstable as easy when adding big power and going faster.
As far as hard cornering stability goes, there are no issues. I've turned the 2750 very hard and never had any problems. The 29 and 32 are a little different than the 2750 because they are taller boats, but I have never had any problems with those boats either. I have found that they turn better with slight negative trim rather than positive trim like a lot of people say for step bottom boats... Also, be sure to monitor your tabs and not have your inside tab down

its been my experience that when something is hard to find
doesnt mater what it is........speaks for the quality of said item
and laveys are no different
im still looking as well\i just happen to be the cheapest sob in the valey!!!!!!!
