I would agree that a 30' sailboat or motorboat will not perform exactly as it would if the extra weight were not on board. An airplane won't perform the same way and neither does your car. Not much difference in taking two fat guys with you who sit aft. I would think that you will need to get a feel for the boat loaded and compensate as necessary.
Let's say you're doing the Great Loop, you just left St. Louis and you're 100 miles south. Where in the heck are you going to rent any vehicle? What bus is there? Maybe you can catch a ride with a fisherman sitting on the bank of the Mississippi
. You get down to Arkansas and you have nothing for 400 miles. Say you want to go up the White River, you can't rent vehicles at campgrounds, there is no bus line to Wal-Mart. You're stuck on your boat. All boating
grounds are not along the Keys, or coast lines of metroplitian areas.
One advantage of having versitle transportation would be that there is no need to carry so much in provisions. Your ability to go ashore will depend on how efficient your system is loading and unloading. If it's a real pain in the tail, you won't be doing it as often. If the whole thing can be accomplished in 15 or 20 minutes, you could have your bike off every night if you wanted to. So, you could save the weight of provisions off setting the weight of that bike, with my 325# bike, I might get the difference down to a bow babe being on board.
Sea walls, docks, ramps, etc. can all be obstacles, they aren't really there for you to off load or load something like a motorcycle. Most marinas
I have seen will have rails along ramps and walk ways and at some point steps, since water
is usually down hill. So, you'll need to scout out your loading spot beyond a dock. I would think you'd be pretty restricted if your don't have a shoal draft
boat. There are many shore lines where you'd never be able to get a bike off unless you rode
it out with a snorkel, the shore goes too far out. So you might be restricted to some dock. In cannels, rivers and lake areas, you can come along side of the shore and off load, especially at a boat ramp
. I have loaded boats in this fashion with other things (like picking up trash on clean-up days). My plan is not to rely on marinas or docks, but to hit the shore. For me, I really would not want a boat that I could never set the bow on shore. That probably means I would not be doing any serious off shore cruising.
I have been eyeing a 30' Voyager that IMO, is heavy enough to take a bike off a fabricated swim platform carrier. That will take some engineering, but can be done, I'm sure. But my underlying option is a scow, landing craft bow gate, aft cabin
with shallow draft
and small OB, hopefully a small sail plan for downwind mainly. No, it would not be as good looking as, or perform like, a Island Packet
or other classic. It would not be as comfortable as a Egg Harbor or a Gemini
cat, but it would be functional and certainly add a new demension to cruising and exploration of inland waters.
I think too that you need to consider the type of motorcycle. My 1600cc cruiser at 750# would be hard to manage, and I would want to set it on a dry surface. You're not riding a cruiser up a muddy bank or lose sand to get to any hard surface road. I think you really need a dirt bike or a dual sport, on/off road capable bike. I can ride out in a foot of water
, through mud or sand if needed.
I doubt this is a really great idea for any blue water types, heading from port to port. I have no idea what the license
requirements would be for a motor
vehicle in Belieze. Keeping track of such matters from country to country and putting up with regulations
would be a real pain and probably not worth the effort. In such places you can catch a bus, rent a vehicle of whatever. Granted. But, for fresh water cruising, doing the Loop or even island hopping in many areas, it would work and expand the adventure.
So taking a "real" motorcycle on a boat is a great way to go, if where you are going allows you to use the bike with little effort and risk.
