If i know the exact dimensions i can have a go for you. But would need at least a picture of the boat and dock to get an idea of size, angle etc. you can get a picture by using your print screen button (prtsc) on your keyboard and then pasting (ctrl+v) it into paint, or any other art package, then saving it and uploading it as an attachment here.
Quick word of advice while i'm here, be careful about asking for people to make specific items on this board, the rules disallow making requests, this board is for artists to offer you free models, not for people to request them. However you may make requests via an existing threads where the author has indicated he/she is willing to take requests, or via direct message.
