You might want to consider making "stumble blocks" or recovery pads for the front of the tunnel. Looking really good.

Jerry, Unfortunately, I have no experience with designing/ making those. Is there a formula to follow when design them? Thanks for any help! Also, were you still interested in me making a cowl for your 1/4 scale project? Please let me know, and I will try and get one made for you soon! I sure hope those "kneeler" plans come out soon from RC Boat Modeler. I am itching to make one. I believe it is my favorite boat!
