I dissagree with some points here
and agree on others
On a 34+ CC you would be foolish not to get 3 outboards
reason being
1st- fact is some boats get better if not equal milage with trips than twins.
http://outdoorsbest.zeroforum.com/zerothread?id=284705 3 outboards will not work as hard as twins pushing a big boat.
2nd- if you have twins and incur a failure on one engine there is no way in heck a single will get a larger CC 34+ boat up on plane. Case in point this past summer good friend onboard a 34 Venture that lost one engine at the edge took 14 hours to make it back to port on the single...thats a bad trip fortunatly the weather was great.
I do agree these boats make little sense in the NE as our weather is so unpredictable.
no matter what it does means 3X the maintenence
Gettiing insurance is tough and expensive
