Of course, these substantial alterations are reflected in sail performance: the new boat will sail worse with light winds, will go slower upwind and probably will go faster downwind with strong winds, will roll a bit less, and will sail with slightly less heel.
Above the 460, below the 458
However, the design created a cut with traditional Hanse shapes that allowed to recognize a Hanse from other yachts. This Hanse lost identity and even if it is nice, it looks now more like an Oceanis than a Hanse.
In situations where the self-tacking jib was enough on the 458, the 460, having more drag, will need a bigger sail to sail effectively. That is why a big genoa will be much more needed on the 460. and therefore the need of the Solent alongside with the self-tacking jib.
Also positive is the increase in interior volume. The most interesting alterations and use of the extra space are especially interesting for charter use. Regarding an owner’s use, the most interesting alteration is the possibility of having three good cabins, with three heads.
The forward cabin is much bigger, especially the bed as well as the aft cabins, and I am sure that this will make this yacht much more successful than the 458.
Having the technical equipment in the aft cockpit locker is not a good idea in what regards accessibility and mixing storage space with technical space.
If the boat is used in relatively short jumps between marinas or anchorages the galley will not be used while in navigation and at anchor or in the marina that huge galley will be very much appreciated by the ones that cook or wash the dishes. Anyway, that is the way that most that cruise use their boats, including charter use, so I would say it makes sense for many, probably the majority.
First the 460, above, the 458
The 460 will be more expensive than the 458. Standard on the shipyard, without VAT, the 460 will cost 237.022€ (the 458 costs 212.925€). That was to be expected because the 460 is a bigger yacht, beamier and slightly longer, including a fixed bowsprit.
