In Topic: do you think the melges 14 will catch on?

Last summer had 2 of my wife's mates kids out. 6 and 10yrs I think, never sailed before or met me before for that matter. Got them helming, they loved it.

Based on the happy-go-lucky, bathing suit-clad, barefoot models, the Melges appears to be targeting a bit more casual user, so perhaps lower performance than the Aero, but the proof will be in the pudding. The Devoti Zero, btw, targets a higher performance market (and has the lower boom to prove it).
 

 
Not sure how you work that out. Boom height on the D-Zero is more than a Laser so even a tall guy like me has no issues getting through even on max kicker (or vang as you like to call it).

The zero, like it's prototype was always intended to be a bathing suit off the beach boat first and foremost and is perfectly suited to that application. Myself and plenty of owners enjoy taking wives and / or kids (in my case just turned 2 at her youngest) out sailing in the zero.
It was launched at the end of a uk winter and consequently getting anyone to take one out in the grey weather in bikini and 9deg sea temperature for some marketing shots would probably end in a manslaugter charge.
It just so happens that the class has a large enthusiastic racing contingent that like to travel to handicap events.
Check Minorca sailing for off the beach pics of zero.

Clue.
It'll bite your head off after it's fucked you.

In Topic: Fiberglass replacement for an aluminum slab. Need to specify the lami

Your findings are that ally is a bit stronger than g10 in bending and tension.
Dare say that the part in question isn't engineered particularly finely I.e wouldn't be sensitive to a weaker material (the Alu part on the bracket has survived use despite extensive corriosion indicating plenty strength margin) but if you were worried you could use a thicker piece of g10 say 25 or 30mm.
Half the density of alu so weight will be equivalent.
I think in this application its mostly the crush but accepting this isn't a rib transom I'd need to see the outboard bracket to make a better call.

Nice boat!
Tensile and flexural stiffness (modulus) generally similar no so sure about strength but www has loads look at matweb or similar. Beware that there are hundreds of aluminium alloys with a big range of strengths. Alloys of Alu of steel have similar modulus (stiffness) but different strength properties.
Aluminium typ 70gpa modulus, steel 205gpa. Quasi isotopic woven glass like g10 maybe 25 gpa.
