I thought it was worth posting a couple more photo's of VMG's maiden adding my initial feelings about the design
It's too early to tell how successful this design will be. But if I was to be completely honest or if I could make any changes I'd probably increase the volume of the bow slightly and raise the transom about 5mm. This is probably being a bit harsh but is food for thought.
For the conditions that VMG will normally race under her beam, chines and tumblehome design should work very well. Her cross section, although relatively narrow has a fairly large balancing area so she should be forgiving to sail tune and gust response. I need to make a small adjust to the jib to help balance the rig and helm, then she should really go well uphill. During the racing last weekend she had a little too much weather helm and I was nearly always feathering the helm. She was still pretty fast despite this but downwind I thought she lacked a little speed. This I hope could be due to the mast or bulb rake, or maybe the nut on the stick but I would like to see her go a bit faster in this area
She's also looking pretty good in the water here.
