The c/b does that, too, as it pivots back nicely. I have a pennant
going fwd to a block then back to a clam cleat under the centre thwart
so I can raise it a little at a time to keep max plane. When you hear
the grating noise, it's time to haul a bit more. Rudder kicks up when
it hits the bottom.

No, not what I meant. Leeboards will _still_ give you some lateral

the way up and there's only 1cm of water under your keel.


That's true. The leeboards are better at the super-shallow sailing. But
they also have twice as much drag.

Yes, but his problem was getting wrecked in the shoals. One
accepts drag as payment if it helps you get out. BTW now is the
time one is supposed to drag Dutch leeboarders out as the prize
example, but it's actually fallacious; leeboards were used as
much because they avoid slotting a hull, and so allow a
potentially stronger hull, as for their shallow sailing
abilities. An entire hull is an advantage if you keep boun\cing
on sand at low tide!


Not sure if the "tunnel effect" is helpful or hurtful, that kind of
hydrodynamics is very picky.

On FLying Tadpole the FIrst, it was hurtful until I got the
leeboards the right distance out and the right toe-in, then it
was helpful...


I have a couple of paddles. They were cheap. They are of marginal use
if you're by yourself. Gotta get some oars which means (re)fitting the
rowlocks. Dunno how I'll go with them, tho, given the restricted range
of movement in the arm. Only one way to find out.



Rowing can be very therapeutic. Remember to take it easy at first,
that's the difficult part. I tend to get all wound up and pull like hell
then suffer later.


Short strokes, Peter, Short strokes. My nymph dinghy only allows 7ft
oars, and it's a real bummer at first to respond to the little strokes
they enforce (hard long strokes tip the dinghy over...


??? Never had that problem.
Another useful technique is to alternate sides, this keeps the stroke
short. It makes the boat waggle from side to side but if you get the
timing right this helps visibility.

It would make my little pram go round'n'round like a coracle...


How is the CCA pine doing as its own antifoul?




Nothing seems to be living on it.



Now I'm curious. What is "CCA pine?"

Apple urgies. Copper Chrome Arsenate pressure-treated softwood.
"PermaPine". Impervious to rot, lethal to borers, white ants,
unfortunate propensity to poison you if used as barbeque fuel,
but also prone to explode when overheated...when it
disintegrates, leaves traces of (you guessed it) copper, chrome
and arsenic. Safe to lean against, not to chew contemplatively.
Sawdust nearly as poisonous as western red cedar.

You _could_ have rigged unstayed, it would be saner if less weatherly
for such a craft.


Not necessarily less weatherly. The engineering would be a bit more
intense, remember he's flying a bigger headsail.

Well, that's a mistake in an unstayed craft. Use a bigger main.
Or dispose of the jib entirely and replace it with the forward
bit of a balanced lug!

Might build an elongated Buehler Pogo next, just for fun. Gaff schooner
rig. I have a Yanmar 3HP diesel engine with g/box that needs a boat.



Ah. I retract my previous statement. Nothing wrong with your sanity
index.


I guess all is relative

There is no relative with a schooner of any sort. It is all
superlative.

Looks like a fun boat, but it's a lot heavier than FT2.

Yeah, but he doesn't need to be a hyperfit young adult to drive
it, either. FT2 is going to come home from Port Augusta soon,
get stripped back to wood-epoxy, critical things fixed, then sold
as is. Harsh physical reality is I'm unlikely to sail her again
and I need all maintenenace time at present to keep Lady Kate
happy.--

Actually, I was thinking of them dragging the bottom...

An advantage that has been negated by modern technology.

Yes much better than a partial hull, I'm sure

Toe-in is "tunnel effect"? I thought you mean the pressure change due to
flow between the hull & leeboard.

BTW a centerboard can be set to angle itslef slightly to windward, just
like toe-in with leeboards, bilgeboards, or catamaran foils. This used
to be called a "gybing" board and it's a big help.

Try shorter strokes.

I meant relative sanity.

FWIW I agree about schooners. I have only sailed a few but always
admired them tremendously. Here it's commonly said that schooners are an
American rig, even an American invention, but one sees native schooner
types all over the world. I'm sad to hear you're planning on selling
FT2, it has been a pleasure to sail her vicariously.

BTW did I ever send you that picture of the FT2 sistership with the box
cabin?

No, the distance I had the leeboards out from the hull was one
thing and their toe-in another (FT1 had leeboards mounted on an
outrigger boom, not directly on the canoe's hull. And the hull
was still widening at the point the boom crossed it, so water
flow faced a constrciting passage, not parallel. A few cm in or
out made a surprisign difference. Then I fiddled with the toe in .)

Yes thanks. One day when I finally update the Light Schooner
page I will put it up.
