Hi doves and Jeff,
I'm new to 5doves, been reading here about 4 weeks, and I'm so happy to have found others who are excited and watching for our Lord's return and soon rapture.
 
 Noah's Ark...my BILaw is an engineer and this is his most favourite subject.  His website www.worldwideflood.com has alot of technical information an interesting stuff that hopefully will answer your questions and perhaps doubts.  Answers in Genesis also has some fantastic articles online and in their magazine.
 
HTH
