Interested in personal experience on a late model Lightwave 45 (galley up) Particularly sailing performance compared to FP, Lagoon, Leopard.
Thanks in advance

The 3 cabin version with daggerboard (single a la Shuttleworth) is making quite a name for itself "Heatwave".

For a production boat it has excellent performance. Lightwave bucked the trend in Oz and use all foam cores. They kept the weight down but the bridgedeck is quite short as a result I would think this would be quite cramped for galley up configutation. The big side windows make for a very nice galley down.

Lightwave is a good company, run by good people who make good boats.

Not sure where the trend was that you relate, but the other big Australian builder up till when it moved offshore was Seawind who use foam core and vacuum infusion.

Sailed a 45 from Brisbane to Sydney a few years back, it was the 45 sport as in it was focussed less on luxury and more to good cruising performance. It was an excellent boat - sailed well, and easy to be on.

i stand corrected I was referring to Perry.

we have galley up on our LW Grande and are very happy with it. Our initial thoughts were galley down, however the galley up works very well, with plenty of preparation space. we have an office in the s'board hull which also works well.

i cannot comment on comparable sailing performance. I have heard from 2 reputable people that Heatwave was clocked at something like 23kts at last years Hamiliton Island race week.....one being Roger Overell who was hanging onto the spinnaker sheet !

ps, we have chartered a couple of Lagoons, a priviledge and a Moorings Leopard, however, not fair to compare as basically the sails were shot on all these boats.

I would not want a composite hull under the water, saving weight in this manner for the sake of going faster is a compromise I would not like, especially when cruising to far flung places with dodgy charts.



To quote from the Outremer web site

"Even though modern composites such as those found in sandwich construction are undeniable for saving weight, an Outremer always has the lower part of the hull built in a very thick monolithic laminate: in the event of collision, no structure in sandwich construction could compete with the strength of an Outremer hull."

I maybe wrong but I understand the new models comprise foam decks and hull sides with solid "joins" along the gunwalls and keel.

Sorry I don't have access to Lightwave detailed construction of below waterline foam/solid sections and their web site obfuscates on the matter.

They need to update their website then:

I built an Airex foam cored Roberts 36 in the 80’s. The engineering data for correctly bonded foam core composites is impressive, especially for stiffness and impact resistance. Boat is still around and going strong.

[Chotu]

Yeah. The no core bottom thing is a big logical error.

Take the same no core bottom and add an inch of foam to that with another skin. Tell me what’s more sound in collision.

Corecell can take an incredible beating. It deforms and crushes under high impact absorbing the energy while still not breaking. It doesn’t crack, it dents it squishes.

The right core (corecell) in the bottom with a little extra glass compared to the rest of the hull is the strongest possible configuration in terms of collision.

Are you sure Perry didn t use foam core ?
