[Public-List] Sling points for haul out (& boat #102)

[Don Campbell]

    From annual lift outs on Alberg 30s the primary winch is just ahead 
of the rudder shoe. Somewhere about the forward lower shroud is a good 
place for the front sling. I have to dodge my knotmeter propeller and my 
depth guage transducer. The slings  should be tied together with dock 
lines to prevent the forward one from slipping ahead . This can be done 
while in the water before the lift and use a boat hook to slide the dock 
line lower on the slings, particularly the forward one, although having 
the dock line parallel to the waterline is a good idea. The Alberg 30 
hull is strong enough to lift the boat from further aft but you will 
have to manipulate the slings if they are on a spreader so that they 
lift evenly , ie. generally shorten the aft sling or lengthen the 
forward one and this takes about12 feet of  sling adjustment with 
associated clevises. I use a 2" x 10" by 14 foot hickory plank that is 
not fixed to the trailer to support the keel so I am able to adjust it 
so that the aft belt  below the hull is easily removed.
    It also helps if you are using a travel lift as opposed to a crane 
with one lift point and a spreader system. With the travel lift, the 
front and back sling can be moved independently so the angle of the 
slings can be changed with the aft a bit high to keep the forward one 
from slipping. Getting high enough for trailers though can be a problem 
if the aft belt is long enough that the system runs out of lift.
     If you are dealing with other Albergs, particularly hulls built by 
Nye boat works like 22's or 29's,  the lift has to be from the aft,  
behind the rudder because there are no bulkheads in the boat at the 
rudder shoe and the boat may crack because the hull is very thin from 
the ballast plug aft  to the rudder. If one lifts from the ballast plug, 
the centre of gravity is so far ahead, that the load is unstable in the 
slings.
    Net upshot is to know your boat and lift where there is internal 
support for helping to carry the load in the slings. If you are worried, 
ask to use the widest possible belts so the load is spread over more 
lifting belt area. (Most crane operators don't like doing this because 
it is too difficult to get wide belts out from under pads after the 
lift, but if you are using the points behind the rudder and in front of 
the stays, there will be little problem retrieving them. An Alberg will 
sit easily on 3 pads and I often use just 2,  - but tie the boat to 
either a wall or a tractor when  all support pads are on the same side  
- which I do every year for bottom paint. My trailer has 10 pads ,  8  
(4 per side) that I use and they are 20" x 20" each so I am not skimping 
on support area because the boat rests on the keel most of the time. I 
can lift her off the keel though with the screws under the  pads if I 
want to paint or work on the very bottom of the keel. No-one is allowed 
on the boat in any of these compromised support situations.)
