twin wells on a 28 footer

just need to work out how to move the boats around to move the engine from one to the other in one go using just the booms

No need - these lovely modern 2GM20s are light as a feather! :)

(Well, not quite, but two of us were able to lift one in and out of the back of my Polo by hand.)

Ignoring the workman ship I like the idea of twin wells.

Belt and braces, less issue motor sailing. I had pondered twin engines on the stern of my trident, 3.5 hp 2 strokes they would of been lighter to move around and to buy 1 more would of been cheaper than buying a 6hp.
 
That poor boat reminds me of a small westerly i saw some years back (not a centaur) the owner had fitted a different engine & the sump was too deep. So he had cut a hole in the bottom of the boat then stuck a roating tin on with self tappers & glassed over it. It solved the sump clearance problem.

I have to say

your plan is not without its merits

if you are going to carry two engines with you as a back up - sensible on long voyages then why not

there is a film here of just such a set up

easier on the back

there are many times when you only need one engine for going into and out of harbours

I think on a 23 or 24 foot yacht with a transom mounted outboard it would make perfect sense

two brackets on the back - usually only deploy one engine for harbour work but you have the second there in a locker for when the chips are down or for when one breaks down

at the moment I carry the tohatsu in the well and the Honda 2.3 in a locker

I do not worry about breakdowns

I always have a get you home solution

Hi Dylan,

Just a thought, but if you are so intent on the inboard/outboard thing, why not cut a relatively small hole midships in the Centaur roughly where the existing engine beds are and acquire a leg seal which you can fit into the hull. Then you would not have to build a ' Well' but simply a mounting transom inside the boat.
This would basically give you a modern leg style of inboard with your four stroke of choice poking out of a smooth hull... This does not remove the concern of petrol vapour collecting in the bilges but a venting fan run for a couple of minutes prior to start up should take care of that !

Good luck in the quest for a Centaur.
 
I think the main problem with this vessels configuration would be it's predisposition to wheelie into wind. And indeed, running before it, beam on and over it.
 
I thought the idea of an outboard on a sailing boat is to be able to lift the leg clear for better sailing?
This thing is like dragging not one but TWO anchors along..

I was lucky enough once to spend a weekend racing on a big east coast smack which had cleverly been fitted with two saildrive units coupled hydraulically to a large central Volvo diesle (IIRC you lose 30% engine energy in this system)..
Manoeuvring was a state of art affair, this thing along with its huge bowsprit could spin in circles and was oft a jolly good wind up to those who didn't know..
