Scroll down to the bottom of the page and watch the video. I'm trying
to figure out if it could be scaled up to 18 feet or so and
reassembled in the water.

Nice little boat and very well done video and site. It could be rescaled
but assembly while in the water might be very difficult because of the
then relatively ungainly size of the two pieces and problems in
controlling them...unless you are talking about assembly at land's edge,
where you could have one half of the boat wedged against the shore bottom.

Thanks for the cite of the site.

I don't know about that, but it sure is a pretty little boat. I prefer
the one that doesn't come apart in the middle. I see the site has kits.
I might buy a kit. Thanks!

We have room to store a 12 to 13 foot dinghy on top of the aft cabin
and use an electric hoist to launch it. Weight is an issue, maybe
400 to 500 lbs tops including outboard, fuel, anchor,etc. It looks
like that Chesapeake dinghy separates into roughly 1/3 and 2/3rds of
its length so I'm thinking 18 ft overall might be doable which is a
nice size. I'd have to launch it in pieces and reassemble in the
water however.

Well, as a teacher of non-math/science-based liberal arts, my
professorial opinion is that treading water while wrestling 12' and 6'
boat sections together that also have to be bolted might be a heck of a
lot to handle without drowning in the process. If you were successful,
though, it would make a terrific video. I'd buy a copy.

Curious, though, as to why you need an 18' semi-portable boat?

Yikes! Assemble in the water?

13 ft. Whaler is 320 lbs dry without motor. 450-475 with a motor.

There are these new-fangled devices called life jackets and buoyancy
compensators that would help.

Heh, need is relative. :-)

There are a lot of guys down in the Bahamas towing 30 ft offshore
center consoles for use as a dinghy. Of course they are using them
for some serious fishing also.

From an assembly standpoint I'm thinking that as long as both halves
have full flotation and some semblence of watertight integrity, that
you could launch them as two seperate boats and then bolt them up in
the water without even getting your feet wet.

It could easily be scaled up... Who is gonna' build it, you?

I get the idea he's going to launch one half with him in it, and then
row over to the other half for assembly.

There are several possible outcomes. among them:

It could work.

It could work and be funny to watch.

It could not work and be even funnier to watch.

In any case, it's adventurous and probably not too dangerous.

Sure, why not?

I've rebuilt and repaired quite a few boats but never done a whole one
from scratch. Tools are not a problem and I've got lots of time and
good weather most of the time. Space is more of an issue but could do
it in the driveway, down on the dock or on the back patio.

It wouldn't be that different from launching the present dinghy except
for the reassembly. The small section would go in first with the bow
painter on it, then tie it off on the stern of the big boat. Next
you'd launch the big section with a stern line on it. Next step
would be to get into the big section, line it up with the small one
and bolt them together. It would be difficult in windy weather but we
try to avoid that even now.

Actually sounds very doable. Just make a bulkhead at the front of the large
section and bulkhead at the back of the front section. Make it two boats.
Then merge them with some large tapered alignment bins and instead of all
bolts, a zeus type fastener. Or on second thought, the alignment pins are
only tapered on the front and have a course Acme type thread to spin on
large nuts quickly. Then a couple more bolts if needed.Maybe need a rubber
plug in the bottom bolt holes while launching. The bulkheads would allow
both sections to float and with a rubber washer on the connectors, no or
little water entering the skiff.

Some years back, Phil Bolger built a somewhat similar kind of boat -
the Folding Schooner. http://www.instantboats.com/fschooner.htm

It hinged in the middle and had bolts to lock it in place.

It is an interesting concept, but had a serious problem.

The loads on the mating and LOCKING mechanisms are exceptionally high.
Early on, the bolts were pulling through the structure.

I have doubts about a long version because of the torque about the
center from weight in the ends. This much less of a problem in a
short one. Remember, you are really stressing the attachment points.
I tried several ways to get the bolt idea to work including putting
foam strips with small holes over the bolt holes to help seal the bolt
holes; kinda sorta worked. I investigated "Slip nuts" for this to
make assembly much faster but never used them. The seat on mine helps
hold the two halves together by means of a slot cut into the seat
lengthwise. I deepened this slot by putting strips on either side of
the slot. This could be carried to an extreme to make the seat carry
more of the torque. I also looked into using "Deep C clamps" available
from Mcmaster-Carr (my toy store) but they seem very heavy. The
stainless "Draw Clamps" from McMaster_Carr installed just below the
rub rail on the outside so they do not extend beyond the rail work
very well. They hold the halves together near the top. The seat
holds them together across the boat. You still need a way to hold
them together at the bottom. For this I got two pieces of 1/8" X 2"
X6" pieces of stainless and bent them 90 degrees in the middle. I
recessed them into the bottom of the back half with bolts and epoxy so
the tab sticks up between the two halves about 1/8" from the
bulkhead. On the other half, I made a recessed receptacle covered
with another piece of SS. This is very strong, probably stronger than
the bolts.
