Lazzara viewpoints

I ve been running a 2009 84 skylounge for 4 1/2 years now... I put over 2000 hours on the C32s in that time and about 4000 hours on each generator

good boat. Excellent system, very few minor gripes. Excellent documentation, every thing is documented, photographed and blueprinted

I ve always been concerned about balsa cores hull but not with Lazzara. All the hull penetrations are documented and solid fiberglass around the thruhulls. As long as nobody drilled holes they shouldn’t have... no worries. Obviously a full survey is a must

with the C32s, the 84 cruises anywhere between 18 and 26kts and tops at 32kts. Right now we re doing a lazy 21 kts on the bank heading to the Exumas, turning 1700 rpm and burning 78gph. Full tanks, provisions and toys...

At hull speed we do 10kts on 20gph.

I love the 5’ draft on the Bahamas. Having 5 guests staterooms plus two crew is unique in an 84. There is also an 80’ which has almost the same layout but without crew quarters in the back, the two forward staterooms are usually used for crew. Good boat too. I ran one for a few days a couple of years ago

we just crossed the stream with 3 to 5 footers off the pier bow. Wind was almost due East but the stream was still a bit crappy from the 20kts northerlies we had over night. Not the best right but the stabs did their job. The 84 skylounge is a bit too heavy. Entry isn’t as sharp as a wave splitting Hatteras but that s the price to pay for the excellent fuel economy.

Forgot something. Divinycel and other foams are great but it is my understanding that balsa offerS better bonding to the glass.

Issues with panels isn’t only a Lazzara issue. Many builders used that Velcro foam backed fabric which after 10 years falls apart. An easy fix is to remove a few panels at a time and staple the existing Velcro fabric To the ceiling or the walls . Problem solved. Must use an electric or air stapler though not a hand stapler !

Well, it can't be such a bad technique, considering that also Azimut started moulding their hulls with balsa cores, more decades ago than I can remember.
Though they moved on from that afterwards, already 15+ years ago...

For myself, when I downgraded to plastic after getting a bit tired of maintaining a timber boat, quite simply I did not even consider anything built in other than solid GRP, at least up to the w/line.
Which BTW I believe is true also of your Hatt, isn't it?
But each to their own, of course.

Yes. My old hatt is solid glass except the decks which are balsa cored. Unfortunately

afaik Lazzara has never had any delamination or core issues so while I prefer solid glass, balsa cored bottom isn’t a deal killer.

Other builders on the other hand including sea ray have any many issues because of poor quality control. Azimut too I believe with the 68 This has come up with graphic photographic evidence here in the past.

One thing I did during the survey of 84 I run now, is compare the hull penetration blueprint to make sure no extra holes had been added (Xducer, TH, etc).

My understanding is that avoiding to drill new holes could not be enough.

Over time, hull flexing can create air "bubbles" inside the core.
In turn, this allows the formation of internal moisture, which is what eventually can root the balsa.
And this is particularly dangerous because you have no way to spot if and where this is happening inside the hull - aside from regularly make extensive moisture readings along the whole hull surface, after leaving the boat to dry on the hard for some time.
Something I never heard anyone doing, possibly aside from when commissioning a purchase survey.

Besides, it's a sort of self-developing process: once any air inside the core begins developing moisture and attack the wood, the void areas tend to progressively extend, making moisture develop faster, and so on.

I'm not suggesting the OP to steer clear from Lazzara boats particularly, mind.
But for myself, balsa cored bottom indeed is a deal killer per se, regardless of the builder.

I know absolutely nothing of that boat, but IPS is one of those things that I call "OMDB" (over my dead body).
So, you can guess how much I'd love to deal with four of them, regardless of how good the boat can be...

My previous comment wasn't referred to vibrations - or any other defects, for that matter.
It's the very expensive IPS maintenance, both scheduled and unpredicted, that make me prefer to steer clear from them.
For instance, even a thin floating line that shafts would eat for breakfast, with IPS can damage the shaft seal, emulsionating oil and requiring a boat lift PDQ to avoid further damages.
I've seen invoices for IPS repairs which would have been funny, if they weren't real.
I do have also reserves on how some IPS-powered boats behave, but these are vessel-specific.
And as I said, I can't speak for the model Chris229 is interested in, so I don't.

I agree with all this and add that they made a name for themselves as having shallow draft and being efficient. The big caveat is they never learned from or fixed the key things they were not good at. Namely ceiling panels always falling down, wall fabric/material seperating from the foam it was attached to so walls looked like shower curtains, and poor gelcoat that never retained a real shine. Even on the last boats they used the same materials.

IPS drives are known for having a lot less vibration than shafts, so I wouldn't worry about vibration as far as that goes. However the 75' LSX is REALLY hard on drives and they all generally have to be rebuilt every 2-3 years at a cost of $30k a pop or so........I sure as heck wouldn't want to maintain 4 engines and drives. That being said, the LSX has a great layout and a ton of room inside.
