He encontrado en un foro unos pro y contras de los barcos de aluminio que creo que son bastante acertados:
Pros
Light compared to steel.
Tough compared to GRP. Aluminium can take a real battering before it breaks. It may dent, but that doesn't stop you getting home safely.
They are different and generate interest wherever you go, if you like that.
Scratches that go through to bare metal are self healing. No emergency paint required like on steel to stop rust weeps.
You will probably come off best if you collide with a plastic boat.
Insurance companies like them. They have very few claims from aluminium boaters.
If properly designed, made and looked after, they last forever. No rot, rust or osmosis.
Cons
Difficult to get paint to stick.
Most designs are multi chined. Round chined metal boats are difficult and expensive to make. Similarly the deck, cockpit and coach-roof all tend not to have too many curves, making them look boxy.
Needs a good insulating lining otherwise noise, temperature and condensation are problematic.
Only expensive and not very effective antifoul can be used.
May be difficult to sell.
Manufacture and repairs require high skills and are expensive.
Wiring and electrical installation must be done especially carefully to avoid electrolysis from stray currents or galvanic corrosion from stray bits of copper.
You need to look after your anodes.

¡Gracias!
Siguiendo con los cantos, yo he resbalado mucho mas en los barcos de fibra, una superficie curva y sin antiderrapante es mortal, a un amigo le falto poco para desangrase en un Bavaria 44, piso el canto del roof y fue a meter el pie en el cadenote, el chorro de sangre llegaba a la cruceta, de nos er porque estaba fondeado en una playa con socorristas, adiós...
Y yo a los cantos que me refiero son a los interiores, los exteriores son fáciles de hacer en curva, basta con soldar un tubo del diámetro adecuado, es mas faena y para los que no le vemos la utilidad nos la ahorramos
40 º creo que son los mismos aquí que en el trópico.
