I want to dry store my 26x at a Marina that can only crane-hoist the boats. Has anyone fabricated a sling that will work on Macs as they don't have the hoist point that the keelboats have. I thought that if I run a sling under the hull with the keel up, it should work (as long as I have poles/separators to keep the sling in position). Does this make sense, is anybody doing this? New to the MacGregor as of last week, I look forward to meeting others. Jim P.

Hoist Away!
Hey Jim, welcome aboard! As I see it, most dry storage is for powerboats anyway. I can't see any reason a P-sailor would cause any special problems. I think all the straps are winched to fit; may be wrong; open to learn if otherwise. BTW, why are you looking at this option? Do they have anywhere to park your rig so that is set-up & you can just back it in? I know with the price of ga$ & all, sometimes it's not practical to keep a towing rig in ready, insured & all. But, hey! Who said owning a boat was cheap? Black Holio, dive in!or forever bore others with your toe dippin' stories of "if only"; (like the guy with the empty space for his Harley). So Jim, dribble or drool; we're not goats, tied to a 3 ft rope, destined to watch our man-hood shrivel; play ball, or pass the dog & beer. Dave, I hope the Punc works for yous, me hillbilly try best he can(winky smiley!).

Hoisting 26S
Each year I remove my 26S from the trailer during the two months I have my boat out of the water. The two lift points relative to location on the hull are approximately where the hull rests on the cradles/bunks on the trailer. I use a nylon sling 8" in width at each lift point. Weight is not the consideration (each sling is rated at 8 tons), however distributing the load at the lift point over the greatest surface area (square inches) of the lower hull is what is important. I also use two steel 8'6" long 6" x 6" square tube spreaders to "cradle" the hull and to prevent damage to the upper hull at the point at which the hull and deck are joined. If you are lifting with a crane, you may consider a longitudinal spreader to keep the slings at the lift points and from moving towards the center.

Thanks very much. Your comments are very helpful. I was picturing longitudinal straps along the base of the hull between the vertical hoist straps to distribute the weight. Is that what you did as well. Jim jpar7301@aol.com

Lifting a 26
I only use the two nylon slings that are placed approximately at the locations where the boat would rest on the "bunks" on your trailer. Slings placed longitudinally between the two slings that are used to lift the boat would carry no load unless the 2 transverse slings were pulling outward (away from the center of the length of the boat). Even if this were accurring the load that these longitudinal slings would carry would be minimal. The weight of the boat itself is not a problem provided you have lifting equipment of adequate capacity. I believe the dry weight is somwhere between 3,500 lb and 4,000 lb empty (ie no water balast, provisions or anything not "standard equipment"). The critical concern relative to lifting the boat is to avoid placing lateral loads at or near the point where the hull is attached to the deck. The deck is designed to support vertical loads on the top of the deck which exert a lateral force outward from the center of the deck to the hull/deck attachment point. Lifting the hull without a spreader between the ends of the sling that is placed transverse to the length of the hull (ie cradles the hull) would place lateral force at the point where the deck attaches to the hull. When lifting force is applied, the hull is lifted upward however, the critical concern is the ends of the slings are not being lifted vertically. As the slings "tighten around the hull" instead of "cradling the hull". It is the tightening of the slings that place lateral inward loads on the hull/deck attachment point. An example would be if you were to attach the sides of a bed sheet between two 26 foot long clothes lines. While nothing is placed on the bed sheet the two lines the bed sheet is suspended from will remain approximately the same distance apart. However, when something heavy is placed upon the bed sheet the wight of the object pulls the bed sheet down and the two clothes lines closer together. In fact, if the weight is long, narrow and heavy enough, the two lines to which the bed sheet is attached will be pulled closer together that the width of the object that was placed on the bed sheet. Without reviewing design calculations it is impossible to know what amount of lateral, "inward" force the hull/deck attachment point is capable of sustaining. The import consideration is that the hull is "cradled" and not "slung". Using the spreaders to hold the ends of the slings a distance apart that is wider than the width of the hull at the lifting points on the hull. If I have thoroughly confused you, provide your e-mail address and I will send you a simple drawing depicting the optimum lifting configuration.

Now I get the hoisting picture, thanks
Thanks for the details, I was a little slow. I'll see if the marina (Brickyard Cove, Richmond)will be OK with the program. Thanks again, you were very helpful. J.P.
