New daggerboard for Potter 19

The one thing I've found about agitation is when someone critiques you and you're bothered by it, it's usually true! If anything, you were straight forward, honest and, in my opinion, did what you could to save him a buck or two and (no pun intended) a boat load of headaches. If anything, he came away from this knowing that his ideas will most likely not be well recieved by the boating community without any personal experience or professional advise.

No, the sow's ear/silk purse thing does not have me. I've decided if I want a fast boat, I'll buy a fast boat, but to start I need something small. Looking at a West Wight Potter 19 (how I found the thread, actually) for starters, then depending on what insight I gain from trailer sailing, look at stepping up to a J Boat or something similar for coastal cruising (I really like the simplicity of the new J/108-109). I'm not in this to lose a fortune, only to gain a wealth of friends and memories and maybe win a race or two along the way.

 

Also, way off topic, but those are some beautiful designs, PAR. The Emily Rose and the Wetlander are drop dead gorgeous. The Murphy is a cool little boat, too. Is this just a "paper-navy" or are these designs in production?

EDIT: Nevermind, figured it out.

 

I know this is a 13 year old thread, but I just found it. I actually did add a 300 pound bulb keel to a Potter 19.

The design brief was to build a small, trailerable sailboat with a modern sail plan (circa 2013) stable enough to fly kites on windy San Francisco Bay. And Easy enough for me to single hand.

I increased the sail area by about 30% on a taller mast. Added a 30” sprit for Code Zero. Jim Antrim designed the keel trunk reinforcement floors and did the righting moment calculations. We put 300 pounds of bulb on the bottom of the stock iron keel plate and I ground it to an elliptical foil shape . Selden spec’d the mast from the righting moment calculations.

The bulb added 4” to the draft. The calculated righting moment increased by about 50%. Angle of vanishing increased to greater than 104 degrees ( however, we didn’t model the contribution of the doghouse, so the AVS is higher than 104.)

It cost me 0 $30,650 out of pocket plus my time (6 months) to build it in 2013, including laminate main & jib, A2 and Code 65 on furlers, and the railer. Sailing her is all about apparent wind. I named her Little Deuce Sloop. She’s a hoot to sail!
