I have a Columbia 36 I keep in Harbor View Marina in the inner harbor. You can come by and measure anything and see how it is done and what the dimensions are on mine it it will help. Send me your telephone number in an email to cam@ccamw.com and I will call you back. I think Jan Smith (the burgee lady) and her husband have a C36 at Herrington Harbor North which is closer. You can find her on the Sailnet list. (She just ordered Columbia Burgees which are very nice and cost us $26 each--I just ordered a spare). Jan's email address is: JSmith1196@aol.com. Any way I can help, let me know. Cam Whetstone s/v C36 - Wolf's Den Baltimore, Md. USA
