I am putting feelers out for eight 6" x 5/8" x 48" steel plates. These will replace the 21" plates on the EZ Loader trailer and give up to 56" of room for the keel...probably 8" more than needed. I can always cut, bit harder to add.

All of these debates about the keel engineering are of interest. I will render an opinion after sailing it. Almost everything has pros and cons. The S2 is a respected sailboat.

The trailer is worth almost as much as I paid. The diesel is likely worth almost as much as I paid. The dinghy and motor has significant value. The free scuba gear is priceless. Don't ask how much I paid.

The original owner may find out about this thread. I'd like to keep it kind and respectful.

Colo,

I'm trying to figure out what you plan to do with the plates. I've converted a couple of trailers to sailboat trailers and if you're doing what I think you're doing it will be insufficient for the task. What I did was raise the roller assemblies up on 4"x 4" x 1/4" aluminum tubes that were welded to saddles that bolted around the frame. Worked pretty well. Most sailboat trailers will use pads or bunks on 2" steel tube that is braced in two directions. I've been in engineering for over 30 years. I can't run numbers but i have a real good feel for this sort of thing.

I think a photo would be quite helpful. Not seeing a way to upload a photo with a laptop.

This EZ Loader trailer uses 8 thick steel plates with 64 rubber rollers to support the boat. That is preferable to the commonly used 4 steel poles and pads.

Not going to argue. Likely impossible to visualize without a photo.

No I didn't see a photo of the trailer. The auction was for the boat with the trailer, more or less, tossed in. Hence "the best and the worst deal imaginable". Many good surprises and one bad surprise.

So far only schnool and krisscross have shown an interest in much more than interference. A bit curious but oh so consistent...

Nice detective work. Is that what this board is about? 17 scripts calling in data...12 domains...15 potential trackers.

Not sure I follow what you are trying to say here about scripts and trackers.

You mentioned an auction so I searched Ebay to get a look at what you bought.

Further checking shows the deep keel has a 4' "draft". Reckon that is at least a foot shorter than a 4' "keel".

Found a few people wanting to give their project sailboat away. Pretty easy to get in over ones head. Also....my boat sparkles compared to many that are for sale. They don't have brown spots, they have mostly large brown areas. Must be the weather.

From the eBay description, he removed the swing keel, added 800lbs of ballast and deepened the keel.

I read this to mean that the deepening of the keel is just adding depth the the existing stub keel that contained the swing keel. The 800lbs of ballast was likely added inside or close to the boat hull in the stub keel where the swing keel would be when retracted. Most likely, the board was 500-800lbs of cast iron that began to corrode to the point of being unusable so was removed, and the added ballast and deeper stub compensates for this, although is placed a bit higher.

If so, this isn't a bad modification and shouldn't change the boat's attitude. It will probably be a bit more tender and point slightly less well than it would with the swing keel fully down, but be better in all other conditions were the swing keel would be only partially down.

If you absolutely must trailer it yourself, and it is a one-time only thing, you might be able to just cut off the stub keel, trailer it and glass it back on when you get it to its home.

That is assuming the deepening of the keel was just simple glass work and does not contain ballast. If it contains ballast, then the modification is even better than above, but you still have to modify the trailer instead.

Sorry but I missed the mark twice. It was a shoal draft keel with a 26" draft. Now it has a 4' draft. Not something that I want to trailer very often at all.

The current keel is almost full, it stops several feet short of the stern.

The trailer is designed for a swing keel sailboat. There are no provisions for resting a keel on the trailer. Thinking I might get a smaller swing keel boat until I get the S2 fixed and find a suitable dock for it. The trailer will be perfect for a swing keel boat.

Sure would be convenient if a fellow could rent a suitable sailboat trailer for a week.

As is, I may have to get the boat in a sling and modify the trailer to fit over the week-end. The closest yards with such facilities are over 20 miles away on a large river. The diesel was pulled due to heating up....probably from plant life clogging the water ports. So I'll have to pull it with a dinghy.

You can, have the boat lifted cradle and all on to a flat bed or car carrier.

If it was local, it would not be unduly difficult to fashion a sturdy cradle of bolted 4x4's, or 2x6's, and plywood. My 20' car hauler would be able to hold the assembly.

It would be easier to make a cradle for a flatbed trailer than for the swing keel trailer with the 8 arms holding 64 rubber rollers.

Not comfortable with making a cradle in a yard 1300 miles from here. I might be half way done then have someone screaming that I had to move everything. Been there.

Too bad it is a week-end. April Fools Day had unfortunate timing for getting things done. What a worthless day for anything but pranksters.

Not going to pull 5700 pounds with anything that isn't absolutely rock solid. I have 5 gallon buckets of "trucker straps", that should help a bit.

I was more thinking a steel cradle. You should be able to pick up a used steel sailboat cradle for a 26' sail boat pretty easily. Especially somewhere like San Francisco.

Not that easy: https://sfbay.craigslist.org/search/sss?query=sailboat cradle&sort=rel

Plus the little 1300 mile distance thing...

EDIT: With the 3/4 ton truck with 488 and 4WD and 37" tires...that is almost ideal for launching 4' draft sailboats with the Extended Tongue. Seems that only ~10% of ramps are suitable for deep keel launches though.

Are any ramps suitable for launching a 4' draft boat?
I think for the most part you are launching with a crane or travel lift at 4'. The vast majority of ramp launchable sailboats I've seen are either swing keel, ballasted dagger board, full keel, shoal keel, water ballasted or unballasted usually around 3' or less. I'm sure there must be some steeper deeper ramps around if you hunt around for them though. Launching at high tide might help.

Opinions seem to vary. A 4' keel is strictly crane launchable. Having figured out that my boat has a 4' draft, rather than 4' keel, that changes things.

Looking at images of normal 4' draft deep keel S2's, I am guessing the deep keel models have an ~30" keel yielding a 4' draft. Unfortunately all I am doing is guessing.

Having to go on the opinions of others, it seems that only a small percentage (maybe 10%?) of ramps are built to accommodate a 4' draft.

I am not the only one who has confused draft with keel....I have to take most opinions as being "unverified".

My trucks lift, 4WD, and 37" tires may give almost a foot of "additional draft capability".

Isn't $300 a typical fee for a crane launch?

I will have to get my boat on the hard for a couple days so that I can properly measure and adapt trailer. I am currently figuring $500-$600 for that. Sound about right?
