I'm afraid Eric is rather out of my financial range. But, who knows, maybe in
few years time? :-)

Lets get back to Inga - any practical information?

If you want an Eric, you may have a copy of the Mylar loft to be finished late spring. It will be released under a creative commons just like my Lynaes dinghy loft. Of course you must purchase the rights from Pat to build it and pay print fees for the loft. But the Inga is nice too. I would consider it. I think the Eric is a better proven boat however from a practical standpoint for deep water and a little more room of course.

Hi, this is my first post on this group. I'd like to ask about Inga, very handsome double ender http://www.boat-links.com/Atkinco/Sail/Inga.html .

I do understand that she's not a modern racer, but is she able to make resonable progress against wind in diferent sea conditions?

I do not know about scaling up. Scaling down to extreme of a pond sailor will not work without Hull and ballast changes. It has something to do with flow, both laminar and turbulent and rheological constants. Trial and error carries a lot of weight in design considerations; you will never really know until you build it and undergo sea trials.

 

The freeware hull modelling software “FreeShip” (now called Delftship) has a scaling function. 

 

You can enter your Offsets Table to produce a “wireframe” view of your hull and then scale it up or down to suit your purposes.  The software will then give you a new Offsets Table and stats such as displacement, wetted area, drag etc etc. 

 

I haven’t tried it except to note that the function exists in the program, but it might be fun to explore. It might give you some idea of whether it’s a proposition anyway …… (Bit of a learning curve to use FreeShip however L)

Is there anybody here that knows about or has any experience with scaling up? At this point I see Russell R as an almost perfect boat but would like one bigger. I've gone through all the posts (reading only a few of course) and it seems that I recall somebody that has scaled up a design (Little Effort I think). A scale up factor of 1.25 gives a 7' X 27' Russell R that would mate fairly well with my 60hp outboard. Looking for facts and opinions.

Hi Patrick,
I yust has cast the lead keel for the 37' Ingrid according to a plam
from Pat. Eric and Ingrid are very similar, so I think you can use this
plan, modifying it proportionaly.

The plans for Handy Andy in MoToR BoatinG and The Small Boat Book are
missing some critical measurements in the profile drawing, those for the
shape of the stem and rake of the transom. I haven't heard back from Mrs.
Atkin about whether they're included in the full size plans, but at least
they could be scaled from the drawing well enough to get you close. If
anybody has the handy Andy plans, I'd sure like to know if those
measurements are on them, and if they are, I'd sure like to have them.

Congrats! I'm jealous.

I'm building the Atkin skiff 'Cabin Boy' at the moment... hoping she'll make a
nice tender for a bigger boat one of these days. Pretty easy build if you know
what you're doing. I don't, so it's a real challenge :-)

"A fabric called Xynoll covers the bottom. This product has a greater abrasion

I want this to cover my entire boat.  And car and house.  Maybe even make some
clothing out of it.  But I can't find it anywhere except on the bottom of this
boat.   Can anyone find me a link that could tell me more about it?

Thanks,

It needs to be fat to hold up that tuna tower! A foot fatter, to be exact. It's
Rescue Minor with a six-inch chine flat on each side, which shows up clearly in
the stern view. With a bit of fairing of RM lines you've got a unique, original
design. Haw.

Is there something wrong with acknowledging the source of one's "inspiration"?
Shameless.

Sometimes you have to choose between your boat and your mother.

Working on Cabin Boy has become something of an obsession for me, but when my mom developed some health issues that required her first-born son to fly off to Florida, work on my boat came to a screeching halt. However, as a side effect, I did develop a severe case of BSA (Boat Separation Anxiety.)

Hi John,
     I don't like wells. They concentrate fumes near the boat, produce
unnecessary turbulence aft, add weight and reduce flotation aft in addition to
causing control cable routing problems in the center of the aft cockpit. They
either reduce usable space in the aft cockpit or make the boat unnecessarily
long and heavy. No point in attempting to make a OB look like an inboard through
bad design.
     As to modifying designs I've done some of that and been mostly successful. I
would also consider adding some ballast, frequently recommended by the Atkin's
and reducing bottom width therby increasing flare. I think a flat sided boat
should have enough flare to avoid tripping on her chines in a beam sea. I would
be lowering the CG by omitting the cabins requiring less stability so reducing
the bottom width would seem the thing to do, however the ammount of reduction
would be beyond my means to calculate. This is, no doubt to myself, the danger
of the modification. Also the inconvenience of the changes in lofting and
construction may not be worth the trouble. Please help me evaluate these ideas
or I may be forced to build a 29' XLNC by scaling up    ..  that also being a
modification. But it looks to me that the XLNC does not have the fullness aft to
support an OB, and rightfully so as it's an inboard. But the other designs DO
seem to have enough fullness aft for the OB. What think?

"If you set out to build an Atkin boat, please do not modify the plans. If
you stray from the plans you do so at your own risk and Atkin & Co. will
take no responsibility for the performance of the resulting boat."

But if we can't talk you out of it, at least put the outboard in a well,
not on the transom.

If you're not afraid of boat nuts, one of the high points of the Depoe Bay
show is the great big group dinner upstairs at the Spouting Horn Friday

I've been googling the Atkin designs, buying a catalogue and several study
plans these last several months. I have a 19' FG outboard I like but I really
want an outboard that goes 10 to 15 knots gracefully and my FG boat does not. It
shines at 18 to 25 and more. I live in a place where Red and Yellow Cedar is
plentiful and would like to build a more suitable boat out of local wood. As a
plan I see Red Cedar topsides and Yellow Cedar everything else. A 60hp OB on any
of the Atkin OB designs is too much power. My 60 Suzuki is in like new condition
and I have no intention of discarding it. I've been looking at Marcia, Wader and
Little Effort to build as a big open skiff. I know it's not smart to alter the
CG as much as would be needed but I see no real difference between Atkin
inboards and outboards. I also realize that subtle differences in the botton
curve or rocker can have significant effect on turning and attitude at various

ballast by removing the cabins. I have a reputation for doing whatever I want
