Mast Life and When to Replace It - SailNet Community A mast generally speaking is not subjected to a huge amount of changing load that would work-harden the material Most of the load on a mast is a compressive load induced by the stay wires, shrouds Those same stays, shrouds serve to fully support the mast section and reduce (almost eliminate) any movement
Spar vs. mast. Whats the difference? | SailNet Community The mast of a sailing vessel is a tall spar, or arrangement of spars, erected more or less vertically on the centre-line of a ship or boat Its purposes include carrying sail, spars, and derricks, and giving necessary height to a navigation light, look-out position, signal yard, control position, radio aerial or signal lamp [1]
creating a tabernacle from a keel stepped mast The loads, once the mast is down, are comparatively light (50-150 lbs at each support) But having the mast pivot above the deck can easily double the load on the deck and greatly increase the cost of the project by requiring the reinforcement in the deck and the lower portion of the mast (tabernacle) to be much more robust in all directions
Mast Winch Install Rigging - SailNet Community Primarily, whether I can just mount them directly to the mast with a mylar sheet or something in-between base and mast Or if I should use a purpose built pad like the Selden 523-042-01 winch pads Presumably if I used the Selden pads I'd attach the pads with the included monel rivets and tef-gel
Mast tabernacle project - SailNet Community The mast has a flat base bolted to it with the matching hinge on one end When the mast is raised it sits squarely on the base, the hinge only keeps it form skidding around, the heavy weight is borne on the bottom plate and transferred down through the compression post A single centered pin will carry the full weight of mast, stays, and wind
Mast (Climbing)- No Halyards - SailNet Community The mast loops -- tied around the mast below the lowest inserted slider car -- relieve the weight and make the job easy Think of this as separating the act of lifting from the act of inserting the sliders cars
j24 Mast boot size - SailNet Community Hi, I have yet another question My mast boot is torn It is a 1984 J24 I have gone to Kenyon J 24 Mast Components And noted that there are 2 mast boots available My next step was to measure the opening From outside the collar around the hole for the mast I have measured 10 5" I
repairing cracked mast with welding | SailNet Community The mast is a proctor, which is 47' and only 6"x4" and has a good deal of flex Even with running backs secured, there is flex to some degree through the entire mast, and especially above the running backs while sailing hard to weather The mast is ~ 1 8" thick, and the plate is a good 1 16 thicker than the mast walls
Mast height question - SailNet Community Mast height is almost always measured from the water But to be sure you know the how high the top of your mast is from the water, measure the actual height of the mast from the deck to the top of the halyard (tape measure) and then add a foot to account for the sheeve typically being below the actual top of the mast
Solo Mast Stepping System - SailNet Community The mast will come down on that, resting at a point that is behind the center of gravity On my mast support I put a rubber roller, like those used on boat trailers, on the frame at the point where the mast would come down on it Once the mast was on it, I would disconnect the hinge at the base of the mast and walk it forward
