Re: [bolger] Re: Idaho and FreeShip (or Delftship)
Thanks for the info. You'll love the Finger Lakes, we lived in Binghampton back in the early 80's and used to sail our cat rigged Cape Dory 14 all over, a lovely place for about 6 months a year. Now it's just too cold for me anywhere north of about Dallas. I was out golfing today with the temp in the 50's, turtleneck, sweater and jacket and I was still cold.

Jeff, I've got a Yamaha 8hp Hi Thrust. It moves along smartly, but I haven't used a GPS yet to know how smartly. I am outfitting the trailer now to start using it on the Erie Canal and the finger lakes. The roof is just over 12', with a 3' closet in the back for the head. Bow and stern self draining decks , mostly to drain rain water, but they make boarding easier because you don't have to step down as far from the dock.
Last summer was the first I had the boat in the water and I can not find any faults yet. I live on a lake full of plastic and pontoon boats, so we always evoke the most smiles and waves from shore as we motor past.
If you look close at the sideways picure you can make out that the stem and transom are both about an inch or two out of the water, thats with 4 teenagers aboard. I've had 6 full grown adults with cooler and beverages and I still can not detect the stern dragging any.
My homeowners Insurance covers me for any boat under 26' and less than 25hp without any extra charge for liability and enviromntal clean up , just an added bonus from staying just a little shorter.

Jeff, Does this modified Tennie look like something you wife might approve of ??
http://groups.yahoo.com/group/bolger/photos/album/1198015615/pic/list
this Tennie is proportionately shortened to 24', but the beam is left at 6'.
We just love this boat.

Mostly will be run on Lake Livingston, a very large lake north of Houston, and my wife has decided she would like room for a private head area for a porta potty.

I'm a fan of this design for the kind of cruising you suggest. I would make the cabin a slotted top with a snap on canvas/polytarp cover. The Bolger drawings show a curtained portapotty.
RE widening the hull. In my opinion. For lake use with smaller motors you probably wouldn't get in to much trouble widening if, but it you went to a Tennessee and modified the cabin to suit your needs, it would make more sense than messing with hull design on your own.
All that said, I'd stretch (not widen) a Cabin Clam Skiff to 22' and maybe even 24' without blinking an eye. Bolger and Michalak have both been supportive of stretching hulls for capacity, and the CS has a dead straight run aft. EZ to do.

Thanks Mark!
Here's that later version.
http://www.softpedia.com/get/Science-CAD/Freeship-Plus.shtml
When I looked for it last, only 2.6 listed @ sourceforge. Now,
softpedia arrives top of the google.
Anyway, it's needed to see some if not all of the truly nice files
Bruce and Stefan have stored here:

Maximo,
This is a link to Stefan Probst's Idaho file. It wants a later
version of Freeship than 2.6.
Hope you can make use of it.

Yes, no problem.
It is worth mentioning that all the Bolger "slab sided" boats like
Idaho, have the common trait that two inches of immersion has twice
the displacement of one inch of immersion. A linear displacement
curve.

Thank you Bruce. Never mind the volume calculations.
But if you find the file in the future, and you can give me 2 or 3
displacement situations, it would be great.
I am not in a hurry at all, I started burocratic paperwork on may 2009... A
SIMPLE ADMINISTRATIVE FORMALITY :)

Máximo, I probably have Idaho somewhere, but unfortunately I use
Free!ship at many different computers at different times and my filing
system is disorganized! Where I am sitting now, I don't have access
to the computer on which I think that need to look to find that fbm
file.
Answering your other questions, no I don't know how to get Free!ship
to make compartment volume calculations. Though, you can use the
scale drawings from Free!ship to estimate the average length X width X
height of the compartments and calculate the volumes manually.
Free!ship does do the displacement calculation of the submerged
portion of the hull. You can adjust the height of the waterline, and
it then can tell you the amount of load which is displaced by that
flotation.

Bruce: do you have Idaho on freeship?
Is it easy for you or the software to calculate the volume of the
compartment at the bow from the foward bulkhead? And also the two small ones
at the transom?
I estimate about 390 liters in the bow, and about 60 liters at the transom.
And also do you get the "weight inmersion rate" of the hull related to the
load?
This numbers are for local cost guard paperwork.
Thanks, regards, Máximo.
