We have netting, which I made on the lifelines
. The dogs go on the foredeck, we throw it over, then bucket down. In heavy weather
we move the sun shade clothes onto the lifelines
(like leecloths) so the dogs can't see out, as they don't like going forward when it's stormy, but if they can't see out ot doesn't bother them!
decks stop the slipping and sliding... you can see the dogs hop from teak
area to teak area, especially when it's rough!
They hate their life jackets, and given the choice between wearing it or staying below in **** weather, they'll choose to stay below.
As for leaving the boat, they are fine inside with the small hatches open. It's not forever, and it's no less space than our land dogs had in their kennel when we were out. More, in fact. Plus they love to get on the berths when we're gone (and they think we don't know - ha).
