Glad to hear so many folks had good experiences with babies on boats, as I'm in a similar predicament to the OP, except I've already got the boat.
For us so far it's been satisfying Mommy more than any concern about the baby herself. Mommy is worried that the interior of the boat does not provide any comfortable place to feed her or change her or for her to sleep in. I admit that the dinette layout doesn't really answer well in this regard, but I think either the v-berth or the dinette berth with a lee cloth might work.
Anyway for one reason or another, our 5-mo old has not been aboard yet. Looking forward for the variables to line up soon to convince mommy to give it a go.
One thought I've had: we use a front carrier most of the time for transporting her around. We use public transit and it's way more convenient than a stroller. I think it will come in handy on board as well, as it keeps your hands free. I wouldn't go up on deck in anything but the gentlest conditions, since it can throw off your balance, but tending sheets or helm should be fairly easy. Also a baby kept close to her parents feels more secure and confident, so I think she would get used to the novel situation more easily.
