Sorry to hear this.
My first boating attempt is next week. Our 30 ft Islander has not left the slip for over 18 months. Last year the water level was so high we could not even get to our boat. Last fall the Corps of engineers ha it so low it wasn't worth sailing. So we buttoned things up and did not return until last week.
To our amazement, everything was OK. Dry bilges, Motor started, all systems we tested came up.
Next weekend we hope to be launching the Maxum cruiser. It's been on the hard for well over two years. I doubt it's re-entry to lake life will go as well.
