which is the best method to repair this leakage, and what are you doing
to avoid gasoline smell in the boat ?

Sounds like it might be a leaky hose connecting your filler port with
your gas tank?
Replace the hose. There's also a chance the hose has simply worked
loose and could be retightened, but if the hose is a few years old
simply binding the clamp more aggressively might prove to be a
temporary fix.

Don't start the boat or introduce any possible source of ignition into
the bilge (such as a power tool or shop vac) until you have cleaned up
all the spilled gasoline and the vapors causing the smell have
dissipated. Be sure to open all the hatches and work with as much
ventilation as you can arrange when cleaning up the spilled gas. If you
wipe up the gas with rags, don't just throw them in the trash when
you're done. Consult your local fire department about the local options
for disposing of rags soaked in flammable materials, but soaked rags
are an infamous source of spontaneous combustion in garbage bins and
dumpsters.
