Take a good hard look

Post by Ixneigh »

Here is the bow eye from my boat. It broke last time I trailered her. This is a graphic example of why some stainless costs more. Ill look for a replacement on line.
I also added a wedge of resin and fiber stand (mat) filler so I can use larger washers.

All stainless steel will do this in the abscense of oxygen, called crevice corrosion. SS needs oxygen to prevent corrosion even 316.

Yes its the oxide that forms over the stainless that give it its corrosion protection, no oxygen means no oxide can be formed and hence crevice corrosion happens as in your picture.

This is common on most types of stainless, some really high grades such as they use in the petro chemical industry however are best part of indestructible, Im pretty sure you wouldnt want to pay for those though.

Had a broken bow eye on my :macm: to. But there was no corrosion there. I don't know why it broke.

Bought a bigger one (just the same I could not get easily). Filled up the old hole and mountet it.

I did not put larger washers inside. On the one hand the bow eye was not so long (well maybe it could be done). But there is another reason: If you really get so MUCH stress on the bow end. I prefere that it moves some millimeter instead of destroying the whole bow with a bit hole...

Ill pay the cost.
Titanium u bolt on allied titanium 2 for 50 dollars.
Not yanking the bow eye out at dusk with people waiting for the ramp. Priceless
I need a longer length that 2.5 inches though. But the factory setup would accept that size. The how is inch thick fiberglass. Its strong enough. I just added filler for better washer seating.

Why go for a real expensive material?
If you worry so take a normal SS bow eye 3 numbers bigger. Will stay very very long with the light weightet mac...

Even with plenty of oxygen SS may fail. I think the are some bad steal out there:

Those are some nasty images Calin.

How did that mast break?

A wind gust on the SF Bay. Not exceptional. Maybe 25-30 knots.
The shackle holding the lower shrouds attachment to the mast. All 26M have it :(

This is more common than you think. I remember the maiden voyage of the LA PAZ trailerable boat made by Coastal Recreation back in the 70's - Roger was aware of that boat as it was built just around the corner from his shop and it was also the pre-cursor of a "Motor-Sailor" that Roger had been considering for some time also - they towed the boat down Baja for a Sea of Cortez regatta about 50 of us were participating in with Aquarius Boats. The owner, Whitney Peden, thought it would be a good venue to introduce the boat to the marketplace - SAIL magazing and a few others were also attending the event.

Mexico was such a great place to sail back in those days:

Well, the LA PAZ had a great sail in the Sea of Cortez, it's performance specs were not stellar, but it got a little press. One thing the LA PAZ taught everyone is that a "Motor-Sailor" without a planing hull was still just too slow under power to really be a crossover hit in the boating market - I think Roger was paying attention. Also, the LA PAZ had a really high free-board making it unwieldy in high winds, (just like some other boats we know!) Yet, the reviews by skippers and others ignored the high free-board - they were willing to accept the disadvantage of the high free-board in exchange for all the interior room they gained from it. Experienced sailors were not afraid of high free-board and wind back in those days - it was a non-issue back then cuz sailors back in those days sailed in more extreme conditions than we do today (they had less forecasting and navigation technology back then so getting caught in bad weather was normal).
Anyways, after the 5 day event in Mexico we all packed up and started north back to the USA.

Image

See that little bow hook on the front of the boat? Well, that hook broke on the trip back to the US. The boat ended up in the sand on the side of the road - it completely fell off the trailer during the trip home. No one is really sure what happened - either the trailer un-attached from the truck during tow, and the ensuing swerving around on the chain broke off the hook, OR the hook broke first and the boat twisted the trailer off the hitch. No one really knows what happened first - all we do know is that the trailer and the boat ended up on opposite sides of the road in the middle of the Baja desert.

Titanium shackle for mast wires. Check.

BOAT - what's that pole in the bow? Is that some kind of self-tending jib?

To me it looks like a the type of pole used on a spinnaker. What do they call them, a Gin Pole?

You might be thinking of a 'whisker pole', but that attaches to the mast via a ring. That one looks to be attached to the forestay. :?

It’s a jib boom also known a deck sweeper aka holy f*c that hurt :) Probably the best material for a new bow eye would be aluminium bronze. Very corrosion resistant and mailable. It would deform rather than just snapping. Titanium and SS are quite brittle.
