Re: [bolger] Re: Delaware Trawler Outboard

No offense meant, John. I love the Bartenders myself.
I thought those wide rails gave some extra bearing
surface for planing purposes. The Topaz is a
narrower, lighter boat the the BT. My experience is
that to prevent cavitation in a steep chop, the lower
unit has to be a bit below what is otherwise optimal,
and with that configuration she has a tendancy to trim
nose-up under top-end power. I have never been lucky
enough to ride on a BT, with or without the rails.
Sure would love to, though. Sam

I got the impression when reading this link that the drawing on the
first page is NOT of Minnesota, but a re-design the builder and
commissioner of it thought superior. Then after it was finished
complained to Bolger about its tendency to yaw!

Bolger says the owner was annoyed when I congratulated him on his
nice boat, but pointed out that I did not have the plans so could
not comment on any problems it might have:-)

Is that perhaps one of the Duck Trap Boatworks variations?

That's not a very nice comment from you, Don ...

This thread is clearly about the Delaware Trawler (check the subject please), not about what you seem to want to talk about, which is putting a Minnesota cabin on a Topaz hull.

Seems like you need to keep your own posts on-topic a little better here, rather than making judgmental remarks about how other people's posts are "not important to the thread".

If I am not mistaken, the WDJ has a very similar leeboard detail to Fast
Motorsailer and Fast Brick. Someone more skilled than I might find Bjorn
Harbo's earlier email describing the damage, I recall, the damage was at the
pivot pin connection point in the side panel of the hull, not actually damage
to the leeboard.

I was just re-reading Bolger's essay about leeboards in BWAOM/ScowSchooner
where he says that leeboards should be as fragile [thin] as you dare, because
light weight is worth the risk.

I seriously doubt that Bolger's attitude has changed much about leeboards,
and that attitude is, in short: that leeboards have pluses and minuses, and
that they have their uses, but are not suited for every boat.

It may be worth noting that Bjorn Harbo's WDJ Schooner, "Esmeralda"
received some damage to a leeboard when it was in heavy weather.

Is it may imagination or has PCB&F sort of gotten away from leeboards
in the latest designs? Witness Fiji, Colonel Hasler, Yonder, I60,
Camper, and that little beauty shown on the home page at Bolger3 - and
several others which have returned to various iterations of a
centerboard or in some cases the box keel.

Even many of his upgrades have only been of boats with centerboards
(BWII, AS 29, Le Cabatin) or fixed keels (Micro Navigator). The only
exceptions I can recall are Fast Motorsailer, Fast Brick, and Martha
Jane and some of these upgrades were also about the sailplan and
include an upgrade to the leeboards as well.

Are leeboards "dead in the water" as far as the PCB&F drawing board is
concerned I wonder?

It seems perhaps that Cartopper marks a signifcant re-thinking of the
centerboard's abilities where a smaller and less intrusive
centerboard, (or off-centerboard) combined with a larger rudder makes
for efficient sailing abilities. Whereas the leeboards restrict to
some degree the practical hull shape to match up with them.

I agree w' Peter but would want to be driving Halifax/Delaware in the
rough. The glass house and flatter bottom of Champlain are more
suited to protected waters. Seems to me the Jochems Schooner has
already proven seaworthiness of the the Halifax hull. A well handled
sail boat should be more comfortable in the rough than the same hull
on engine power alone.

Lastly, the Topaz hull with a more durable cabin design like that of
Halifax or Minnesota is will be faster on the same power.

Really lastly, making the Halifax a motorsailer seems redundant with
Jochems Schooner and Fast Motor Sailer available as proven designs of
which several have been built.

Don
The context of my comment about the Minnesota was building a similar
cabin on a Topaz hull which is similar in length to Minnesota. The
characteristics of Minnesota's hull are not important to the thread.

Well, there was ice on the windshield of my car last week, a rare,
thing, but proof that it gets cold here too.

The model is an imaginary rowboat shape that I dreamed up,
intended for plywood lapstrake, with curvy lines, exaggerated
whitehall shape, but extra wide beam for stability and capacity.
It is on my short list of about two hundred boats I intend
to build next.

The last three feet of Topaz [everything aft of the motor mount]
amounts to an ornamental motor shroud. It could be omitted, but the
looks would suffer.

In my opinion, a big part of the theory behind the Topaz hull is that
the loading [people/gear] is centered above the middle of a flat
bottomed hull. This allows, regardless of loading, the shallowest
draft. This, in turn, allows the low powered / low wake nature of the
hull. Also, a lot of the shape of Topaz is determined to take
advantage of the sweeping curves possible with long plywood panels,
with the benefit of quicker/cheaper construction. Big sweeping curves
happen to look 'boatlike' and be 'boatlike' too. The twisted panel
forefoot cutwater gives a sharp entry line.

Clyde, I agree. If I wanted more planing speed in a
Topaz, I would ask PB about squat boards like a
Caulkins Bartender (or choose another boat), but I
wouldn't change the shape. She would loose her
moderate speed capabilities. Sam

Another option would be to consider Fast Motorsailor or a boat with an

Anybody know what happened to the info on that design?

As of a month or so ago, PCB had not finished the Delaware concept,
which he said would become "Halifax Explorer". Motor sailer is Wm
Jochems as Delaware/Halifax uses that hull. With the rocker in that
hull, we're probably not going to make 7knts but the extrapower of the
high thrust 25 should handle tides and currents or as acticle says"pull
disabled boats off the lee shore". My concern is how fast a squall can
come up on the Chesapeake Bay and even in a large sailer, the prospect
is not pleasant. My desire for a little more speed would be to escape
weather. The advantage of the Topaz hull is the quiet, no wake ride even
at moderate speed, Maybe Sam can correct me, but to cut the stern off
square is to do away with this advantage. I look at the quiet, no wake
advantage as efficient use of power, at least that's my interpretation.

I checked the Champlain specs here:

http://www.myasylum.com/sbf/messages/630.html

... and saw some finished Champlain boat photos here:

http://4dw.net/cosailor/ontario/champlain.htm

Champlain specs call for a 52 gallon fuel tank, less than half that of the Delaware Trawler 110 gallon tank, thus I suspect it will only go half as far between fill-ups. But Champlain does have about the same 6-7 knot cruising speed I guess.

To me Champlain looks rather "short and top heavy" when compared with drawings of the Delaware Trawler, but I suspect its accommodations may be better. Any idea which one will handle rough weather better?

Nels,

With the Delaware Trawler weighing about 1000 pounds more then the
Champlain,I suspect that she would be slightly more expensive to build
presuming we use the same quality standards in materials for the two
boats.I do not know WDJ's displacement off hand but if you have it
handy just remember;the heavier the boat is the more it will cost.

For these shallow hulled boats with virtually completely enclosed
helms and accomodations,great speed on the water would appear to be
something of a waste of energy.This strikes me as particularly true
if one considers that for many boaters,once they leave their
dock/quay or ramp it is almost 99.9% certain that their ultimate
destination is their dock/quay or ramp....:-) So why not make the
time on the water last as long as possible and make it all the more
relaxing by traveling at sailboat speeds.The shallow hulls allow for
some interesting out-of-channel,near-shore exploring/traveling while
the fully enclosed helm and accomodations make concerns for most
weather irrelevent.
I certainly like the idea of using an auto-helm for long open
passages,especially if that means I am free to rustle up a warm
meal,do some meaningful chart work or just to enjoy a more relaxed
moment on the "throne".Traveling at around 6 knots means that things
will not hurry up or sneak up on you too fast before you can make
the necessary corrections.
Of course,having some extra horses,in hand, might prove very helpful
if one routinely cruises on rivers with strong currents or in areas
that have considerable tidal effects.Nothing worse then being in a
boat,which tops out at 5 knots, going against a 4 knot current....we
can all walk faster then that :-D

Beyond that, I cannot help but think that "slow" boats are also the
boats that no thief cares to steal since there is little built in
thrill with the captured prize...........

Peter Lenihan,eager to launch his own slow-boat-to-no-where some

IMO another handsome and practical cabin arrangement by Bolger is his
Minnesota.

If I were to build Topaz, I would widen the aft hull to accomodate
the "outhouse" and perhaps improve planing, and use Minnesota as a
pattern for the cabin, just because I like the way it looks.

Thanks Don,

You are correct. Also I was incorrect in my recall of the hull speed
when I said 13 mph. It said in the article it is capable of about 13
mpg at about 61/2 knots.

So it needs a lot more power and is considerably slower than I
thought. I wonder how the total cost and time to build would compare

I think this should be similar to most sailboat outboard installations.
Practically every one I see puts the prop deeper in the water than you'd see
for a planing hull.

The few time I ran my AF4 at displacement speeds with a large load (such as
towing disabled boats back to the dock) the shallow prop would suck air from
the surface and ventilate if I tried to apply too much power. That's the
reason why all those sailboat installations are so deep.

I agree that pitching completely out is unlikely. With a shallower prop
ventilation is more likely than with the prop 6" deeper. Short or long, it's
hardly worth arguing about, though.

Someone earlier predicted a top speed of 13 knots. With only 25 HP and that
deep-bellied hull on a 22' waterline, 6-6.5 knots is a more beleivable
maximum. After spending a couple of weeks knocking around the Thousand
Islands on Bruce Hector's 5.5 knot houseboat, I've figured out that in an
ideal world I'd like to go just a bit faster. Not a lot faster, mind you:
it's just that 10 knots cuts travel time in half (or doubles the distance
you can cover in a day) without getting into big gas bills and requiring
intense concentration at the helm. Also, for a boat like Delaware, you can
bet your that I'd install an inexpensive autopilot to allow for more
relaxing passages where it was open enough to allow it. It might be that the
autopilot would even make running at 5.5 knots acceptable!

I would guess Delaware would is designed to take a 20"
shaft, just because it is getting so difficult to find
the short shaft motors. If you take a sea over the
motor-head on Delaware, it would mean you are in
breaking seas so extreme that the buoyancy of the hull
cannot lift fast enough to clear them, and at that
point you would have problems no baffle would be
sufficient to cure, in my opinion. In my Topaz, I
have had the stern pitch out in a steep chop, causing
some cavitation--which I doubt would be a problem with
Delaware, given the rocker of her hull--but I never
had a wave come close to threatening to drown the
power-head of the motor, thank God. The stern just
lifted up over following seas.

Isn't, generally, 15" considered short shaft, 20" long shaft, and 25"
or 30" considered extra long?

IMO, ask Phil Bolger which shaft he recommends, but I bet the 15"
would fit, and be safe too. [Talking out of my hat...] I don't see
that hull 'pitching out in a seaway'. Bear in mind, that a
displacement hull has a large sternwave that would mitigate the
'pitching out' risk.

Regardless of shaft length, isn't it proper to mount the motor so the
cavitation plates are at the level of the hull bottom? IOW, a longer
shaft requires a higher motor mount, and the height of the propeller
doesn't change. Mounting the propeller deeper increases drag of the
lower unit through the water, harming speed and fuel efficiency. [and,
the cost and weight of the motor]
If it were me, I'd want the 25" shaft to put the prop deep enough to prevent
pitching out in a seaway and also to allow for a taller and safer transom
height.

If you are starting from scratch, there's no reason to specify a short shaft
motor anyway. For example, when I built my AF4, I set it up for a short
shaft motor witht he idea that there would be more short shafts on the used
market. Had I realized that I would eventually buy a new motor, I would have
built the transom for a 20" shaft instead.

Of my big pile of Bolger models, coincidence has it that
Delaware model happens to be closest at hand.

I see a motor well slot, not 'wide open'. Wouldn't a following wave lift
the aft of the boat with it?

FWIW, there is a scan of the MAIB in Bolger5
I think the High thrust 25 is a 20" or 25" choice. I don't think the
stern is in the water at cruising speed of about 7 knts max. More use of
power will just rocker the bow up with very little gain in speed. The
speed limitation is one of my concerns and I've been thinking of a
Delaware (actually now a Halifax Explorer) type house on a Topaz hull,
with still a relatively low power T 25. Clyde

Denis,

A short shaft OB is plenty,really,since once the boat is underway
the hull shape(rocker,to be specific) will ensure good and ample solid
water for the prop.

Unless you plan on anchoring by the stern,in an exposed
anchoraged,during a storm or running backwards on windy days,no wave
is going to normally flood the engine.Anchored from the bow,she will
ride like a duck with her nose to the wind and waves.Underway,she will
cruise faster then most wave trains.In particularily heavy going,where
you find yourself caught out in "small craft warning" conditions,a
prudent skipper will avoid running downwind at any speed less then the
waves for fear of a)being broached and/or b) getting swamped by an on-
coming wave.

A "baffle" or some such device would be just another thing to fuss
over getting it right since it will have to be some how made to lift
so that the engine could be tilted up when not in use etc,etc.....

It is a very handsome design and I hope PCB&F'S do eventually get
someone to actually commission it and they,in turn,find the time to
finish it......oh well,hope does spring eternal!

Sincerely,

Peter Lenihan, tossing in my own 2 cents worth of opinion....

That's a fair question Denis, and you might consider faxing a query
in that regard to PCB&F. Be sure to include return phone and fax
number:-)

Looking at the cartoon I think there is room for a long-shaft if the
engine is mount is higher and the coaming would still hide it. Also
in the write-up it says you can access the spark-plugs on the T9.9
called for - from the side deck. Also they stipulate a 5 HP back-up
motor with separate fuel container, just in case. So it would seem
to be about as protected and reliable as most outboards on a
displacement hull. Cruising speed is what? About 13 mph or 10 knots?

I really like that design myself. Reasonably simple to build, fuel
efficient and nice looking. Would hardly hear the motor from the
helm I would guess.

Hi. I've been looking over the cartoon of the Delaware trawler
again. It seems like I always return to that boat when trying to
decide my next project.

One question I have is the stern portion of the boat. I like the idea
of mounting the outboard in between those two "tails". I'm assuming
this is a short shaft (15") outboard in order to keep it from poking
above the surrounding structure? The only potential problem I see is
a following wave flooding the outboard since the aft section is wide
open. I suppose some sort of baffle could be worked into the design
that would help and not be too ugly. Any opinions on this?

Thanks,
Denis
