> Which Bolger boat fits this description?
Yacht Tender design #499
Auray Punt design #599
Tahiti Tender design #655
Donovan's Tender design #647
...might fit.
Of these, I only know of the
Auray Punt. Which obviously
planes, and might row nice?
Can any body describe the
other three? What were
#655 and #647?
I can't help but observe that a stone skipped across a pond appears to
'plane'..... An airline pilot once observed to me that, given enough power,
one can fly a brick (non-Bolger type).

I remember someone's comment that an Elegant Punt made a better yacht
tender than a Nymph. Perhaps more stable with the flatter bottom ??
The Nymph probably look better.

I'm still not convinced.
The Nymph, a displacement dinghy shown "planing" behind Selkie has
her bow safely high in the air, because she has a curved keel in
profile. A proper planing dinghy with a straight keel line aft will
want to ride flat, and may well put her bow under at times, in waves
or wake. I had mind to building a Bolger Bee, which would give a
fast fun planing boat, and also a tender. I asked Bolger who said
Bee could make a tender, but a heavy weight would have to be set in
the stern for towing. Now this would be a pain in the backside, and
I would certainly not trust Bee's towing ability for my outboard to
be that substantial weight.

Another criteria for a yacht

good looks, which SpurII has.

Bolgeristas,
I started a related thread about dinghys over in Boatdesign under the
subject "Wake" that may be of interest to you all. I had thought of
copying and pasting them here, but there are too many of them.

Most tenders will plane empty, even if they are not planing hulls. For
maximum Bolger input on this check out the Nymph planing behind Mark
Zeiger's Martha Jane "Selkie" at the bottom of

Surely he is only meaning a tender for a planing mother ship?
I can't see any merit in a planing tender for a displacement boat.

I was just re-reading Robb White's
article about the perfect dinghy,
in the June 1, 2002 MAIB. Whew!
Is that guy long winded? Four
columns into it, he gets to his
(really excellent) point, that
dinghies used as yacht tenders
need to be able to both row *and*
plane well. He describes the
ideal shape as similar to an
aluminum canoe;
[Robb White:]
"I found out that a long
(about 16 feet) narrow
(five feet or so) very
light (less than a hundred
lbs) skiff with a planing
boat configuration to the
bottom will work just fine...".
My question is:
Which Bolger boat fits this description?
My initial reaction was SpurII, but it has
a bit of rocker in the bottom plank, and
probably would get squirelly if you towed
it at planing speed.
