[Public-List] Exuberant - Alberg 30

Different subject...I'm not a member as yet, but I had been looking at '67 Exuberant (hull #273) at Certified Sales in Mendon, MA (Salvage Yard).  The boat has a recently refitted 3-cyl. Vetus diesel with approx. 48hrs on it and had suffered damage I believe during Hurricane Sandy (damage to keel, toe rail, coaming, push-pit, stanchions, life lines).  The fiberglass repair is relatively straightforward and I thought it would be worth repair for a sale price of a couple of thousand (it was initially offered to me for $4000, I had planned to offer less).  However, I had the boat surveyed and it turns out that there is also unassociated deterioration of several bulkheads and evidence of some "persistent" leaking through some chainplates.  Depression at the mast step is evident that the so called Alberg 30 fix has not been retrofitted and may also be contributing to the poor condition of the bulkhead (although leaks were noted to be a separate contributing factor).  Anyway, bulkhead repair is beyond my level of expertise and commitment level.  The rep at the salvage yard has indicated that he is going to have the boat crushed.  If anyone is interested in this vessel for repair or perhaps would want parts it may be a good opportunity.  He is going to salvage the engine at minimum and I believe it also has good sails, mast, and perhaps other useful hardware.

I had heard the association had taken up other restoration projects, would there be any interest in restoring this boat (picture attached)?  Below is an itemized list of issues from the survey:

Repairs to the damaged fiberglass would be relatively straight forward. In the course of the survey
other issues were discovered and are itemized below:
* Deterioration of the main transverse bulkheads carrying the rigging loads outboard at the hull
tabbing.
* Depression of the deck under the deck stepped mast step
* Evidence of persistent leaks through the chain plates
* Evidence of deterioration of the chain plate fasteners
* Evidence of leaks through the hull/deck joint - by oxidation of the through bolt nuts
* Extensive damage to the port side toe rail w/ deterioration (rot) throughout
* Heavy damage to the cockpit coaming port side
* Deterioration (rot) of the fwd bulkhead of the port cockpit locker
* Damage and deterioration of the stbd cockpit locker access hatch
* Heavy damage to the transom pushpit railing, stanchions and stanchion bases
* Heavy damage to the port side lifeline stanchion and stanchion mount midships
* The forward cabin door does not close indicating some distortion of the hull
* Deterioration of the transverse partial bulkhead at the Vee berth fwd
* Disarray and deterioration of DC wiring and plumbing respectively
* Age related deterioration of the interior joiner work and varnish

Thanks,

Clay

Wire does make a difference and I've used both. Furlers still allow for stretch and stretch means the draft blows aft, not good. If you pump the sail up and leave it pumped - the shape will be ruined. Best bang for the buck remains wire to rope tail.

And furler guys, back off the tension when you get in.

Just to add gas to the flames, people should realize a couple of things 
about stretch - first the SAIL stretches as well, and it is polyester. The 
other thing is that it is NOT the absolute stretch that matters - if the 
halyard stretched out an extra 34' as you raised it, but then was absolutely 
rigid once raised, it wouldn't matter, you just end up pulling twice as long 
(think of having a block arrangement to raise the main where you pull twice 
as much halyard as the sail height. There are a couple of stretch related 
items that are important for mains - first, you never want to even get close 
to unloading the halyard - eg the halyard should never flap around, second 
the change in tension in the halyard due to tension changes in the luff 
should not cause significant length changes in the halyard. It is this last 
point that people actually care about.

Now, the problem becomes knowing what the various values are and how much 
you care about sail shape.

The change in tension - this will be due to wind speed changes (gusts etc) 
and heading changes. Anyone have a tension meter they could put on their 
halyard to measure this? For standard 3/8" polyester double braid, each 100 
lb change in force changes our 34' halyard length to the head of the sail by 
5% * 100 / 2000 where 2000 lbs is half the break strength (Bool's law). That 
is 0.25%, or 1". With either 7/16" halyards OR Sta-set x (the stretch is the 
same), it would instead be 1/2". The stretch with wire/hi-tech line is 1/4" 
per 100 lbs. Whether a gust load causes 100 lbs change in the halyard 
tension, I really don't know - I would guess it is between 100 and 200 lbs, 
so between 1/2" and 2" of stretch depending on material. This value is for a 
hanked-on jib or a main. Roller furled jibs generally do not exhibit much 
change in tension due to wind speed/heading changes - the luff is fully 
supported, so the horizontal wind force
 isn't translated into vertical force along the luff, only towards the 
leech.

This doesn't really tell us how to decide - for myself, I like my polyester 
halyards. I can do a wire to rope splice, so the cost isn't much different. 
I do race, but fairly informally. It would mostly matter on higher-wind, 
gusty races because there, the difference in having a 1-2" flatter sail 
means the gust would spill off quite a bit better and I wouldn't heel/round 
up so much in the gusts. Alternatively, maybe I will try sta-set x or 7/16" 
halyards (or both) if the 7/16" fits. I might consider changing and see if 
it makes a difference. First I have to see how my new main is this year :-)


Bill.
