Steam Schooner WAPAMA help needed figuring out a couple dimensions
« on: December 29, 2016, 07:28:37 pm »
hey guys I finally came across some awesome drawings and the cool part is they have already been corrected of errors by the team that was going to restore one of the ships.

I am giving a link to all I have on the ship along with my excel sheet for the offsets and my curve files

here is my problem I got all the curves tested in solidworks and they indead have been fixed up however I am missing the info for a couple dimensions to enter into the curves for the stations to complete them.

I am missing the Half-Siding, the Deck Sheer and the Plank Sheer Dimensions to finish the curve files off properly

http://www.proflooney.net/Steamer-Schooner-Wapama.zip



it is The Steamer Schooner WAPAMA Circa 1915



above is zip file of everything I have  its the drawings, an excell file I made of the offsets, and all the curve files I made for importing into Solidworks (unlike some other cad programs I have to make each curve file as a separate file



these are some really really nice plans and I want do do a good job on it as its one of the few sets of drawings where i can actually understand them as a newbie to ship modelling. I just am having some problems at the moment figuring out what those 3 missing dimensions come from so I can enter them in the proper space in my tables



thanks

Joe

The offset is all good and even matches the lines drawings.  But not complete I can't find which ones, however I brought it in and tracing the rest then the fun trying to loft the surface

ok here are the dimensions for the sheet I used for layout to match the full scale

sheet 00006a i used for profile on the front plane and also for the stations on the right plane. I didnt cut the sheet I just used the wole sheet but the drawings are different scales thus the different szes.

for profile view:

Length: 3167.24720294in

Height: 2446.57474368in

For the Stations:

Length: 2111.33276274in

Height: 1630.92208528in

using those dimensions when you do the curve files in cad program with the offsets I have in the excel file they match up perfectly

Bonjour Joe,
I am not a specialist at all, but I find that the shape of the hull under the stern is not in phase with the installation of a propeller. I would have seen a verticale surface  at the propeller shaft exit and a horizontal one for the keel heel which will support the rudder. I have seen no propeller or rudder representation in your .zip => Are you sure the drawings are correct ?

I havent drawn the keel and rudder area in yet I am trying to get the hull shape tweaked first and add them later. it is easier to draw that way

OK no problem, you have answered to my possible concern  :-)) 
Besides this, The propeller is quite original and I wonder if it is efficient... I will go on following your build with a great interest.
