Re: re:ballast/gas
I believe this scheme is too heavy, complex and expensive to be
consistent with the spirit of a Bolger boat. Besides, there is a
simple, readily available source of compressed gas for evacuating the
water from the ballast tanks. It is available to most of us by means
of a change in diet (pass the beans). To those who have reached a
certain age (and *we* know who *we* are), diet is irrelevant. The
only other requirements are a stout piece of hose, good timing and
excellent muscular control.
Imagine the expressions of wonder on the faces of onlookers as your
beloved vessel approaches the launching ramp, spewing misty billows
from its blow hole like a broaching whale. Next, imagine their
expressions when the sweet sea breeze, as gentle as a zephyr, carries
the aroma across the waters to the dock and they stagger back in
horror and disgust. I ask you, does it get any better?
As an added benefit, any excess production can be tapped to fuel your
HOB,

For a minute there, with your change in the subject line I thought we
were talking about the hazards of eating out. After reading your
message, I realize that it was a continuation of the old topic, but
only after ROFL.
It occurs to me that the instructions below can be extended:
1. Use scooner rig with equal length masts.
2. Incorporate retracting trailer wheels into hull.
3. Deploy masts amidships, to each side.
4. Do not stop at ramp, proceed to airport.
Gas turbine might increase efficiency. The rigour of designing for
this process will probably result in a very lightweight, streamlined,
and fast boat.
I can't bring myself to edit your message.

Better take turns, too. The other guy draining with previously

Respectfully accepting the suggestions of several members of the group, may I suggest that a
synthesis may have been arrived at.
It appears that the ideal water ballast structure might well be 1. A high pressure cylinder of
sufficient capacity to provide the desired ballast, 2. the ballast tank drain to be a section of high
pressure piping led directly aft through the boat's transom, 3. A pipe attached to a vacuum producing
device so that the tank can be quickly filled, 4. A pressure and check valve protected fill pipe for
introducing the water ejection medium, either an air/propane mix or on-board generated acetylene gas
(add carbide to the tank), and finally, 5. A source of ignition, perhaps a ring of non soakable spark
plugs at intervals around the ballast tank.
When preparing to haul the boat and empty the tank, align the boat and its trailer along the axis of
the hauling ramp and hit the switch.
The forceful jet of water exiting the transom will drive her forward onto the trailer, the continuing
thrust will drive the trailer up the ramp and out (First get your SUV out of the way) and, as a
finishing flourish, after the water is gone the propellant plume would blast out the boat's stern
with a long blaze of flame. It should really be quite pretty for a night haulout.
Once per marina.

It used to be a common trick to pressurize 40 g fuel drums to pump em
out in this part of the world until, one hot day. a drillers offsider
and his drum of diesel ( not very explosive) did a messy flying Gibe
( to keep it boaty) I wuldnt reccomend gas of any kind, especially a
flmmable one or one that can send yuo to sleep.
gee yur ply is expensive , last sheet of 6 mm gaboon i bought was
$55.00 australian , Every sheet 8kgs , perfact
Folding schooner progress is slow this week due to having to earn
money and stuff, such is life. glued a couple of frames in tonight,
but those two last elusive sheets of ply are still a dream at the
bank. I saved on woood for the bilge boards by working out how to
scarf all my offcuts of HDO (like MDO) into 2 big enough piecs.
this will be a sure test for epoxy scarfs.
last weekend we got in a gloriousday on the lakein a good 15 knts .
the yawl rig on the june bug was fun , but a bit scary for the kids,
the new seats were so comfy you wanted to go to sleep
cheers all Paul
