Sailormann Re: Chopping off your keel. Don't do it. If it really bothers you, see if you can trade with the guy who has the Potter, and then order a new centreboard. You can raise it in the shallows and still beat to windward hen it's down.

Re: The Potter with no Centreboard. Order a new one and put it back in if you are going to sail the boat. It is a really important part. Trust me.

hanggreg Thanks everyone for your input. I am going to leave well enough alone. I'm sure I can just be more careful of where I go in the Bahamas and FL. And I do want to sell the boat in a year or so and move up once I get more experience sailing this boat. I appreciate all the input.

hanggreg Thanks to everyone for your input. I'm going to leave well enough alone and just stay out of water that may be questionable. It sounds like there are plenty of places to go in the Bahamas and FL with 5'5" draft and I will want to sell the boat next year and move up once I have learned more. Again THANKS!

Gary M This has been done quite a bit in my club, generally on bigger boats like C&C 45s that draw (7-8ft?) they get a bulb from Mars and bolt it on. They are located in Toronto which is just 3 hours from us.

I would not do it and it is expensive not to mention a lot of work.

camaraderie greg...you don't NEED to reduce your draft to see 99% of what others in shallower draft boats see in the Bahams. I don't see the point of the work or expense.

alaskapotter19 I have recently purchused a potter 19. The centerboard(which weights about300 pounds ) was taking out and replaced with 600 or so pounds of lead and put in the hull.
I havent"sailed" the boat to much yet. however we have moterd the boat quite abit and it feels very stable and seaworthy. the centerboard was replaced with a marine plywood which was fiberglassed over.

hellosailor Mars Metals are the folks to ask. They can fabricate a bulb that will correct your loss or righting moment, but as others have said you are also losing the foil and that has to affect your pointing ability. The folks at Mars might be able to tell you how to check on that, or recommend a naval architect who could run some numbers to give you a better idea.

If you really want to get into shoals...it might be better to look at selling the boat and getting a centerboard boat instead.

Also bear in mind, once you circumsize your keel, the resale value of your boat may also get chopped down.

pigslo I can see why you want to do it. The damn thing is made of lead and so it slows the boat down not to mention it gets in the way when you are in shallow water. That tongue in cheek aside, did they offer your boat in a shallow draft version? If so then the engineering has already been done. My boat was produced in a centerboard 4 foot draft version and a 5 foot version. I own the centerboard version but if I were going to convert I would just get the specs from one of my sisterships.

georgellop ..... where do you want to go in the Bahamas?

SailorMitch Several years ago one of the big glossy mags had an article about a guy who did just that, and added a bulb to the end of the keel to make up for the loss in weight. he did work with a naval architect. If you check www.marsmetal.com they may have that article on their site. They also can help you with the project, which, as others have said, is not to be taken lightly. Mars advertises quite a bit, too.
