Oz,
You know Neal claimed he had a shelve in his old main. I'm thinking now that his old main was so blown out that he is under the impression that the blown out section of his bolt footed main was mistaken for a shelve. I'm not sure I didn't have a lot to do with him getting involved with a true fitted shelve main. When I ordered my new main from North I forgot to mention the shelve and it came without. Do you think he got the wrong idea when I mentioned my oversight? I'm beginning to think this is his first Free Footed main he's ever own. He doesn't know how the hell it works and what it can and can't do. I've tried to clue him in on it, without success. Ole Thom |

If you will check the pictures of Capt neal new sails you will see that the main is not free footed. JR Thom Stewart wrote: Oz, You know Neal claimed he had a shelve in his old main.

JR,
That picture of his Hong Kong Main shows a shelve. JR, a shelve fitted main is a Free Footed Main. The shelve is ONLY to prevent air from creating a vortex, Is you look at that picture you will see that the airfoil shape carries to the very bottom of the sail, then the shelve (which is open) carries straight across to the boom. Just like a "shelve" the reason for its' name. JR, think of your own main REEFED. You have a free footed sail with the access sail folded and loosely tied to the boom . It should never be tied tight enough for support. |

Sorry my mistake, I had just never heard of a mainsail that was attached to the boom with a bolt rope be described as free footed.

I don't know Thom...... the only quick glance I had of Capt. Neal's photos
didn't seem to show a free footed main like mine.... I always thought he had a bolt rope along the boom. I'm probably wrong about the configuration. As well I don't think my main has a shelf and it's a free footed design with full battens. I had it recut to that from the original North Main. CM "Thom Stewart" wrote in message ...

"The SILVER boom bends more than the GOLD boom. The bending boom will flatten and depower the sail which enables the lightweight sailor to go faster in more wind." Since your boom is bent opposite to the bend referenced above, it could only mean that your sails have higher power! Muffin Man "Capt. Neal®" wrote in message ... Dear Group and Lurkers, The usual bunch of babbling buffoons in the group's Peanut Gallery has been making fun of my well-repaired boom. They include Whining Oz, Gay Gaynz, JRBadbreath, and Crotchety Ole Thom. They seem to criticize my sturdy boom on the basis of two things mainly. 1) It is heavy ruining light air performance. 2) It is slightly bent thus ruining sail trim. They cannot claim it is weak because it has held up under more than ten years of hard sailing since I repaired it and it is still far stronger than the original extrusion was. It is so well sealed that there still is not a speck of rust or corrosion to be seen. 1) Allow me to debunk the 'heavy' claim. The pipes I used as internal sleeves weighed a total of ten pounds. This means the boom is ten pounds heavier than usual. The epoxy I slathered them with when I slid them home with the help of a 2X6 sealed them and glued them to the boom but the epoxy's weight is insignificant. Some say this extra ten pound will ruin the sail shape in light-air sailing. Simply not so, as more than ten pounds of downward force is placed on the sail when the mainsheet is hauled down as it must be even in light air. All the slightly heavier boom does is make it slightly easier to sheet in the mainsail. 2) Allow me to debunk the second claim concerning a slight bend ruining the shape and trim of the mainsail. Simply not so. Just look how racers intentionally bend their mainmast with fancy backstay pensioners in order to flatten their mainsail for better performance. My boom accomplishes the very same thing because of the bolt rope in the boom and the shelf foot which closes when the outhaul is tightened. The bend has no effect upon the sail shape when the outhaul is eased because then the shelf foot opens up and the sail relaxes along the boom and foot but when the outhaul is tensioned, the shelf foot closes and the bolt rope in the boom tends to flatten the sail. This is such an efficient system that, frankly, I am surprised nobody has thought of it before. The first racer who decides to use a bent boom and a bolt/rope shelf- footed sail will do well because he will have a definite advantage over staid and unoriginal minds (or lack thereof) as demonstrated in the ignorant individuals listed above. These two simple explanations demonstrate how lacking in knowledge everyone except Gilligan is when it comes to knowing what makes a fast boat like "Cut the Mustard" even faster. CN |

Yeah Oz,
Water they can collect. Sailing here in the Pacific NW I'm very aware of it. So is everyone that sails with me. On my old boat,which had the shelf when I said ; "Ready to Tack" they would scamble to windward as soon as I said; "Helm's Alee" As the boom swung across the cockpit the shelf would turn itself inside out with the wind and dump a load of water in the cockpit and Lee side seat. One dousing trained them very rapidly. This Main sails a lot drier. Ole Thom |
