I've a few questions for GI15 builders or plan owners out there. I'd like to know:
1)the bill of material specified to build this boat, and in particular plywood sheets number and usage (which thickness for the bottom, sides, decks, etc).
2)the dry weight of the boat
3)if the designer specifies ballast, and, if so, which kind and how much of it.
Thanks in advance!

Hi, Pippo,
I have the plans to this boat. It is a looker, and from all accounts, a good performer.
BOM: Plywood
2 sheets 6mm (side panels)
2 sheets 9mm (bottom panel)
Probably another 2 sheets 6mm for side/fore deck
2 9mm for side and stern sheets
1 12mm for rudder c/b and case. The last three points are from memory, so don't quote me, but they are very close. Less than 10 sheets all told.
Ballast: two water ballast tanks are integrated into the hull on each side of the c/b to be filled from a port on the top of each tank. These are only used when single handing in a rough go. I think they hold 110lbs/55kg? altogether.
There is also a removable sand ballast box that goes fwd of the mast -- to be used when single handing is recommended. I think it holds 22/23kg of sand.
Over all weight is slightly over 300lbs according to the specs -- and this without the ballast factored in.
Hope it helps. I have a friend who is looking to start building one this winter.

This won't answer your questions, but I think you'll find it an interesting. The link is to a commentary by Australian Ross Lillistone on performance of the Green Island 15 (http://www.woodenboat.net.nz/Boats/Boategret/Boategret.htm)

Ah, Sam, you are killing me! If you can post a pic for me, I will send you one that shows the GI 15 hooting along in 30mph winds. You game?

You mean seats, not sheets, in this line, don't you?

Folks,Ross Lillistone is a professional builder of traditional wooden boats & is a master craftsman. He has a small workshop in Winnum-Manly,a bayside suburb of Brisbane Australia,on the shores of Moreton Bay,a large waterway popular with local boaties.
You can see his website at www.baysidewoodenboats.com.au (http://www.baysidewoodenboats.com.au)
Ross is a gentleman who gives freely of his time to other boatbuilders who contact him on most any matters.I have built a 15' surf /exercise ski to his design which turned out fine & have seen his workshop & the boats he builds.His love of building,knowledge,& quality workmanship are well known here in OZ.
Contact him direct,or see some of his articles he writes as a regular contributor in a great little mag here called Autralian Amateur Boat Builder at www.boatbuilder.com.au (http://www.boatbuilder.com.au)
Look in the archives or,better still,subscribe to an entertaining little mag dedicated to amateur boatbuilders.

Pippo, the sail area is 106 sq ft. The main is roughly 72sqft and the jib is roughly 34sqft. I say roughly because the dimensions are in meters.

I've bee trying to look at that web site but it's not currently available. Googleing it gives no results as well... :confused:

You mean that all those 3/8", 1/2", 2' lead to more refined results? :D

Pippo - Glad you liked the article. The overlay of Egret's lines (one of my all time favorite boats) with the GI 15 was quite interesting.
The GI's broader stern should increase sail carrying capacity all other things being equal.
Interestingly the GI’s stern reminds me somewhat of the Mississippi yawl/lifeboat in Parker’s Sharpie book too...

Mike - I've sent the photo. Hopefully it'll work. If not, we can try something else.
Thanks a bunch!!!
