Although it is common, I think starting cruising by heading west across the Pacific is a bit much. It is like going from high
school to graduate
school, leaving out college.The distances, hazards, and lack of
repair services and supplies means it is best to master cruising first. YMMV. If you go down
Central America, through
Panama and the
Caribbean, you would be well experienced, and the
boat proven, before starting your first
ocean crossing. There will be many opportunities to add or change
equipment and do
repairs in the
Caribbean or on the
east coast, and also on the other side for the failures that occur at sea. I spent 12 years in Europe and barely scratched the surface. Going around the world in 2-3 years would be a lot more rushed then you think now - better to shorten the trip and have time to enjoy what you do see. With your limitation with the
dogs, and considering how many passages are not that much fun (Red Sea anyone?), you would probably be happier to just set your sights on Europe, at least to begin with. You will always have opportunities to reconsider as you go.
I went down the
west coast, from
Oregon, to and through Panama. I went east across
South America, staying in
Curacao,
Venezuela and Trinidad. These days getting close to
Venezuela is a very bad idea so I would
head east as far as I could - either
Columbia or the ABCs (Aruba,
Curacao, Bonaire) then north and as far east as I could hold, making for the
Dominican Republic or
Puerto Rico - then
head down the Lesser Antilles to Trinidad (depending on the season and how much time would be spent there). In late April or May head north to
Bermuda and across to
Ireland and onwards. I would leave the east coast for the return trip, unless you had a preference otherwise. The return trip would be to the
Canaries and Caribbean, then the east coast. Consider doing the Great Loop, going up the
Hudson River, west on the Erie
Canal, through the
Great Lakes then in the rivers at Chicago and down to the Gulf.
Remember that such long distance travel is constrained by the seasons. If you left California in the
winter (after the
hurricane season is over) you would have to be poised to cross the Atlantic in April or early May from the NE Caribbean so as to get across before the tropical storm season (no east coast cruising without costing a year). In Europe, even in the Med, you are not going to be cruising during the
winter months - you will be land cruising from a base in some marina (which may be hard to find). When it is time to return you will head for the
Canaries in the late summer (before the equinoctial gales), cross in November, December, or even January depending on
weather and hang in the Caribbean until April or May then head north and east for cruising the east coast. At the end of that summer you will probably want to be back in the Caribbean and perhaps heading for home. If you
work that out you will see that even that short of a trip is going to be an effort in 2 to 3 years. Going around the world has similar constraints, but greatly compounded by your need to avoid
Australia and the presence of
piracy in areas along the way. It is possible to do but count on spending a lot of time at sea, making
repairs,
provisioning,
customs, and far too little time getting to know the land and peoples along the way. Just something to consider.
