Hi Steve, Thanx for the interesting link. We’ve been studying "bumps" or “ serrations’ in nature for many years (our day job). We found they work well “ coming and going”. On the leading edge, they provide more linear inches of cutting surface as well as single point contact for penetration. A natural example would be the teeth of a shark. Early arrowheads mimicked these edges. Modern mimicry would be serrated blades on knives. In plants, they have similar functions in dissipation. On the trailing edge, they affect flow, such as the trailing edge of a bird ’s wings and tail. I’ve often thought about experimenting with serrated trailing edges on sails. Interesting thought you had on keels and rudders. (Maybe it’s time for me to contact Harry on the sails and pick Jerry’s brain on the underwater parts). Another example of sailing invention using mimicry: Back in the ‘80’s, Gail and I were selling an interesting boat called the "Sail Fin". It was a flat transom (for motor) canoe. It had a simple sloop rig with a dagger-board. The dagger-board had what was called a “Whale’s tail” fin at the bottom of the board. Similar to “wings” on some sailboats, but the “tail” was split and extended aft for about 2 feet. In addition to added ballast, the rear section was flexible and when the boat was rocked side to side, the “fins” worked like swim fins and propelled the boat forward. Used for trolling or moving location without motoring or sailing. sal 1985 M15 #361 “Justus” In a message dated 5/13/2011 4:49:56 P.M.

It describes how bumps on whale fins reduce drag. http://tinyurl.com/Whale-Fins If that link doesn't not work, search for "Whales" and "ASME". The bumps are on the "wrong side" of the fin from a conventional wisdom perspective. They allow a higher angle of attack before stalling. Unfortunately this is useful only in limited circumstances. I wonder if there may be a practical application to a rudder or perhaps centerboard. steve Steve R.

I am in the final stages of getting the M-23 ready to launch. The final barrier coat went on today followed by the bottom paint. The boat arrived with the head removed and I would like to put one back in before going on a long weekend cruise. Any suggestions that would help in replacing it? I also would like to update the mast head light while the mast is on the ground. Any suggestions for modern replacements like an LED type? And finally my son is planning on flying in for a Chesapeake Bay cruise for a few days to blow the dust off the boat come June. I have only day sailed out in the Bay and would appreciate any suggestions of places to sail to. We are leaving out of Chesapeake Beach MD. Thanks in advance! Robbin M-23 and M-10
Robbin How about Solomons, nice harbor and good eats On a side note how did your rigging turn out, I havent heard from Winston yet, hopeflly this week Gary -----Original Message----- From: robbin roddewig <robbin.roddewig@verizon.net> To: montgomery_boats@mailman.xmission.com Sent: Sun, May 15, 2011 9:11 pm Subject: M_Boats: Marine head and mast head light I am in the final stages of getting the M-23 ready to launch.

Hi Gary, thanks for the recommendation. I am replacing a few pieces that look a bit worn and the halyards but really the rest of it looks fine so I am going to go without any official inspection. When I really looked over the rig it appears to be in great shape and way over built so I feel confident that it should be sound. Robbin On 5/16/2011 3:40 AM, tommyval@aol.com wrote:

Robbin, You must be getting excited about the possibility of actually sailing your M-23. I have been following your work via your web page and I must say, you've been very busy. I'm not sure how far you wish to sail but I have sailed the lower part of the bay with Doug, Mike, Al and Bill. Keep in mind, I have an M-15 to the skinny water isn't so much a problem for me. I have sailed from Tilghman over to the backside of St. Michael's then over to Oxford. This was a nice weekend trip. If you want to go further, then I would suggest Solomon's Island. The cliffs are nice to look at and the wind is always great. If you really want to push the distance, then you could head to the tip of St. Mary's county and head up the Potomac for Kinsale. They have a nice marina there where you could eat and shower. There are a lot of nice coves, that you could spend time in with your M-10. I'm sure you will have a great time. Make sure you send out a full report of the maiden voyage.

Hi Robbin, Gentleman never go to windward :-) The Choptank river is just a beam reach away from Chesapeake Beach if the prevailing winds hold true. It is a wonderful cruisng area if you do not care for marinas. There are marinas at Tilghman wharf (14 nm) and Oxford (19 nm). There are too many nice anchorages to discuss but Dun Cove, 3 nm north of Tilghman Wharf up Harris Creed is one of the favorites on the bay but can get crowded. Leadenham Creek (19 nm from Chesapeake Beach) is another nice spot and is not much farther than Dune Cove. It is 5 nm up Broad Creek. With the really long boards with few tacks it won't test you sailing skills but could expose your anchoring skills. There is a small current through most of the anchorages so make sure your swing room is ok when the wind dies. Enjoy as it is a fantastic area.

We all know that cabbage travels well. And if you like cole slaw but are not comfortable with keeping the cabbage mixed with a mayonaisse based sauce, I found a great recipe. Instead of the mayo use a mixture of coconut cream with a splash of pineapple juice. It'll keep all during the meal and can be kept down below in the bilges close to the hull beneath the water line. Enjoy. Joe Seafrog M17 #651
My spreader base was riveted to the mast and was just a wee bit loose. My boat bible, This Old Boat by Don Casey says that rivets holding the spreader base to the mast is not a good approach but was not uncommon on older boats (like my 1978 M-23). Problem is compression loads on the mast tube. So not wanting to make a major mod and sit out more of the sailing season I decided to replace the rivets and roll the dice for one season. I purchased a rivet tool (Arrow) at the Depot and another at Tractor supply. The one from Tractor Supply did two SS rivets before cracking in half and the one from the Depot made it through three rivets before pretty much stripping. So in the event that you every want to work with riveting on your boom or mast, get a better tool(s). I ordered what is supposed to be a professional tool from Jamestown Distributors. We will see how it holds up. West Marine sell SS rivets, but not tools (nice)! I plan on making new rigging next winter and the spreaders will be made over with sleeves between them then as well. Mast is up and my boat is now just waiting for a lift over to the pond! I will miss my little spot on the hard, it almost feels like home after all these months. Robbin M-23 and M-10
