A year ago I purchased a Manta
42 and have the camber spar jib. Although I have only had this cat for a year, I've owned several mono's before and will be heading offshore
in our cat in few months like we did with our previous boats.
We've had no problems at all handling or dousing the jib in high winds. Generally, the sail falls quite nicely into its lazy jacks. But, for other situations, we have a downhaul rigged which leads back to the cockpit
. It's no problem dousing this sail.
The only drawback that I feel that the camber spar rig has is that we do not have the ability to reef the jib as you would with roller furling
. On the other hand, the jib is quite small so I am not sure that reefing it will be a concern. My manta brethren tell me that lacking the ability to reef the jib has not been a limitation.
I do know that several Manta's that have headed offshore
have carried a hank on storm jib
that goes on the forestay above the doused jib. But, it must not be that necessary because nobody that I have talked to has ever ended up using it.
We've been extremely happy with our Manta and purchased it for some of the same reasons that you mentioned. The Manta owners also have a VERY active private forum where any question that a newer owner like myself asks gets answered nearly immediately from many long time owners. If you do choose a manta you won't have the palatial space like some other 42' cats, but you'll get a very well built boat with lots of attention to detail in the systems that actually sails
