Long story short was running about 21 kts in the Putt in bay on Lake Erie area with a boat following to close behind me and a boat to my starboard when a 35' boat head towards us to port suddenly cut across my bow. Was afraid to cut my throttle because of the boat behind me . Took his wave hard enough to crack my hull. Now I'm waiting on a area recommended glass shop for an estimate to give to the insurance company to move forward. Got a 30" crack at the water line rib and fairing let loose on the inside on the bow support. Shop first opinion looking at the damage told me it looks like it will cost roughly 10 to 11,000 dollars to repair. As long as that doesn't balloon it shouldn't be a problem. The insurance company has already got in touch with me told them the same story and the shop rough estimate and it shouldn't be a problem. All I know in this current boating market I wouldn't want to be replacing my boat. Beating myself up pretty good on I should have done this or that. The boat coming up my back side put me in a bad spot if I would have cut my throttles I'm pretty sure he would have not been able to miss hitting me if he was even paying attention considering how close he was following me.
