26M Owners, what are your parts questions?

[DLT]

Have you seen this?

[Captain Steve]

All those shop drawings are neat!

[Frank C]

Hmmm - parts listing show the "annual quantity" usage at 600 units (steering, for example). I suppose there's a good stab at Roger's annual sales volume on the 26M ...

Can you actually reference these numbers to purchase gelcoat? When I had my boat repaired, the MacGregor factory wouldn't supply any information for matching gelcoat.

For owners of a 26M, it might be a good page to save.

I got blue and tan gelcoat (have not used it yet) from Bill at boats4sail at a reasonable cost. Not that hard to get.

Well, it does answer the age-old question over if the windows are plexiglass, lexan or some other acrylic....

Is Plexiglass a trade name and the same material as Perspex?


1 Excellent UV resistance- PERSPEX products exist where they has been used for over 30 years outdoors without significant deterioration. PERSPEX are warranted for a 10-year outdoor service life.
2 Excellent Clarity- with 92% light transmission PERSPEX has superb clarity and transmits about 10% more light than glass.
3 Safe and easy to Use- PERSPEX sheet is often used in glazing applications and is a safety glazing product meeting the relevant safety standards. It is half the weight of glass of the same thickness with at least 5 times the impact strength and with none of the breakage problems associated with that material.

Plexiglas (properly spelled with a single single "s") is the Rohm and Haas brand name for polymethylmethacrylate, sometimes called PMMA or MMA. It's similar if not the same stuff and usually shortened to the more generic "acrylic".

Lucite was the DuPont brand name for acrylic. Plexiglas and Lucite have always been competitors, but R&H elected to devote their development effort to their brand while DuPont was distracted with ruling the world, and established Plexiglas as pretty much the generic term for the product, now commonly spelled with the lower case "p" and the second "s", sort of like kleenex. It's unknown whether Rohm and Haas care that most people (apparently including MacGregor) use a mispelling of their trade name is the generic term.

The Lucite trade name now belongs to Lucite International. Perspex is a third brand name for acrylic which I believe has only ever been in common use in the UK (&, Austrailia, etcetera). Though I can't find any reference to the original owner of the brand name, I assume it was a Brit plastic company, but now also belongs to Lucite International as well and they use it to describe a particular form of Lucite.

Probably more than you wanted to know.

In a rare flash of mental clarity

1201 winches = 600 for trailer plus 600 for mast raising gear

1 extra for a gybing centerboard option

[DLT]

Very funny...

But, there are only 600 trailer winches.

The winches Moe refers to are the Lewmar winches...

Also, the winch on the trailer is different than the winch on the mast raising system...

[Catigale]

Alas, mental fog again....

I wish we had something like this for the X, though much of it is usable as is.

It caught my eye that (at least if this is to be believed as the complete specification) the trailer bunk boards are not pressure treated. No wonder they rot out after 3-4 years. I usually stick up for Mac for his cheapness, sometimes verging on the fanatical, but this $2-3 savings is truly unconscionable.

Other stuff we suspected, like the acrylic rather than polycarbonate windows, and the SS hardware is the cheaper 302/304SS rather than the super corrosion resistant but quite a bit more expensive 316SS. The mast and boom extrusions are the lower strength 6063 rather than 6061

Interesting illustrative note, the bow roller fab drawing says "bend or weld, which ever is least expensive". As if we had any question what really mattered. And the roller itself can be "nylon, Delrin, Teflon, or approximate equivalent". Might as well say "any solid material". With nylon selling for approximatley 1/5 as much as Teflon and Delrin 1/4 as much, is there any doubt? BTW, Teflon and Delrin are Dupont trade names for PTFE and acetal, respectively. And, what a surprise, the bow roller material was recently changed form 10 Ga. (.135") to 11 Ga. (.120"). That saves at least 11% (but less than $1) in material and probably a few pennies in forming cost. Gimme a break!

I was wondering whether the 600 piece number is the projected usage, or simply the max transfer rate for planning purposes, equal to 200 working days approx x 3 boats per day.
