Fairline use a foam grid in between the hull skin and liner that's glued on top .None gluing ,poor fitting is gonna hard to pick up between the 100,s of foam grid sq,s
So seems to work for them .
Given a choice as you can,t beat solid hand layered mat and marine ply bonded in stringers bulkheads etc for durability going forwards and ease of survey
Click around Dave Pascoe site for "grid liners ". If this link does not work

Not Mr popular for obvious reasons David Pascoe

Porto, having been to the Fairline factory on a number of occasions, I can tell you that you what you say is not correct. Fairline start by making the hull - gelcoat first then fibreglass matting added using matting and resin rolled on by hand. The stringers go in next, they are foam cored*, and again the matting and resin is hand laid. Next the (marine ply) bulkheads are added and these are also glassed in. There is a separate liner that slots onto of the bulkheads that are now part of the hull strucuture. These are again glassed in to add rigidity. Finally the deck it added onto of the hull and liner. [I think this is correct, no doubt JFM will correct me if I've miss-remembered.]
* As JFM has pointed out to you in the past, the strength is in the fibreglass so it doesn't matter if the stringers are formed around foam or plywood.
Fairline do use vacuum bagging on some models / parts. Even then they over engineer the process by adding a layer of fibreglass by hand before bagging additional thickness onto the hull.
As you'll appreciate, there is no cutting corners and the end result is a very sound boat. If you ever want to visit the factory to see how it's done (properly) for yourself, all you need to do is ask and I'm sure it can be arranged!
Not all manufacturers make them that way....

Azimut of the period should be have solid glass hull bottoms, but the sides used to be cored (Diab PvC) and tended to continue under the waterline.
Princess 38 (hard to find) and Fairline 38 Phantom are solid glass bottoms with PVC cored sides (above water-line).

New 48 series (Squadron, Targa etc) was advertised as fully VB, and the new 53 (developed on the 50 platform) had to go into this method of production. Not sure if they did it in the 53.
JandJ engineered the process plus hull design etc for the 48 series.

I never said that foam grids couldn't be used successfully; it can and it is.
I saw 3 brand new fl,s @ the IT dealer ( stock boats ) in San Remo the other week .
Quality oozed from evey pore -wrong word there ?
I looked at evey component in detail ,you know ,teak tread thickness ,hinges , guard rail thickness etc etc
Could not find a single fault .I also made note of the HIN,s --17 "platers " so to speak .
Quality wise for a decerning well monied punter they are in a good place .
But David Pascoe raises some good points about grid boats or suedo grid if you like in terms of faster production and difficulty for surveyors to access the inside of the grids , to reassure there's been
1- it was properly glued together evenly from day 1
2- it -the two layers have not de -glued .
It's interesting to here the switch to VB ing taking place .
Any how Pete any suggestions why SS still build boats the trad method only ? -( no grids ,suedo grids ,VB ing , liners etc --adding huge labour and material costs .
A far cry from Phil Pophams -robotised ,just in time previous JLR production history ?
