Sredinom juna prošle godine proinut je patrolni brod Paolo Thaon di Revel (P430), klase Paolo Thaon di Revel (italijanska RM). Upada u oči, bar meni, čudna konstrukcija pramčanog bulba.

To mu dođe bulb za brze brodove.

Valjalo bi vidjeti blisku video / fotografiju broda u plovidbi, po mogućnosti iz zraka.
Tada bi slika opstrujavanja mora oko pramca puno toga rekla.

piše, da su u biti jednostavno produžili vodnu liniju broda i tako pridobili jedan čvor na max brzini (max brzina premo sorazmerno ovisi od dužine vodne linije)
koliko sam čuo za bulbe (one klasične): oni smanjuju otpor i pomožu u ekonomičnosti broda ali samo u određenim brzinama. Nije to primer na Paolo Thaon di Revel
