There are some designs of boats, mainly multihulls, that can use an outboard, even in fairly heavy seas. This is due to the design of the boat, and the fact that the outboard, is situated in a relatively protected location, between the two hulls, and not hanging off the transom. However, for most monohulls, an outboard isn't really all that viable a choice for off-shore use.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.

As I mentioned, we are trying to do what we can to minimze the vibrations that can be tough on a bad back.

It sounds like an inboard will help by helping to minimize the pitching of the boat. But I should have also asked in my question regarding gas vs diesel inboards, which produces less vibration?

gasoline engines generally produce less vibration due to lower compression ratio and higher rpms.

If you are concerned about vibration I would say gasoline only. But isn't the constant motion of a small boat on the water also going to create back problems then? After all, a sailboat is a 3-D exercise in staying vertical as the boat moves.

HS-

Might depend on what the problem with the back is... some of my friends with back problems have been given yoga balls to sit on, in the place of office chairs, since the movement helps strengthen the back muscles and abdominals.

The last time we were out on the water his back fared well, even though just a few days prior it was a problem on dry land. (In fact, we used an outboard to get in and out of harbor which is where we started kicking around the idea of going with an outboard.)

We are hoping that the motion on the water, if not too rough, will actually be therapeutic.
