Good man Mark, I know we can rely on you for test, test and test again...it does pay.
Have a word with David, I know he'd be happy to help you out with any information that you need. Besides, I'm following this with great interest...I'm on the point of saying 'yes' to a 1/72nd scale Skipjack, which I believe originated from The Scale Shipyard, so I'll be facing the challenges you're having to overcome.
Good luck,
Rich
