ATTACHMENT PROBLEM

Jimenez arranged to borrow $500 from Smith in a secured transaction in Chicago.  Smith asked Jimenez to sign the following document:  I, Jimenez , hereby grant Smith a security interest in my 1999 Bass Masters bass boat to secure repayment of a loan made by him to me today.  Jimenez originally refused, but he later sent Smith an email containing the text of the document.  Jimenez did not write his name at the end of the email, however.  Upon receipt of the email, Smith delivered the $500 to Jimenez .  If Jimenez defaulted on the loan, could he argue that Smith has no security interest in the boat on any of the following grounds:  a) no signed security agreement; b) no witnesses or notary signatures; c) no info about loan terms?
