No. Safe charge rate for marine dual-purpose batteries is amperage at 1/8 to 1/10 amp-hour capacity, so eight to ten hours for a 80-90% charge (100% is going to take days of trickle). Charge rates are high at the start, taper off as charge builds, so an hour might get you 30-50% charge coming up from almost full discharge, or add another 20% if coming from 50% discharge.
The charger will be self-limiting (constant voltage, amperage limited) to start with, then as the battery charges, amperage is limited by the battery pushing back as its voltage rises. If you want fast charging, you need a whole different battery technology, like some of the lithium technologies, which require more sophisticated charging systems.
