Rick,
My boat is from 1976 and is hull number #100. I guess they built and sold a lot 
of 38 back then! The original owners manual lists the beam as 12' 0", LOA is 
37' 7" and the LWL is 29' 7". I have been under the impression the the 
prototype was (were?) the only mk1 and the production boats were all mk2s. I 
have no idea if that is correct.

  Subject: Stus-List Does anyone know the HIN break between the 38 mk1 and 
38mk2?


  I need some help in answering an inquiry from the handicapper of NCPHRF, 
based on the data I submitted in my recent PHRF application.

   

  Imzadi is a 38, HIN 047, with a build date of 01/76. I presume she is what 
we'd call a Mk1. Someone on the list has a boat with a HIN in the high 80's, 
and describes his boat as a Mk2.

   

  In submitting my most recent PHRF application, I used the tech specs from the 
photo album. The handicapper has asked for some clarification, because the PHRF 
base rating data shows the specs of the Mk1 and Mk2 to be the same and that 
there is a common base rating of 117 for both models.. A review of the 
available specs and brochures show that most of the data is common, but the 
data for beam varies over a range of 11'4" to 12'3".

   

  In my application for my Mk1, I used 11'4" for beam. That's the number in the 
tech specs for the Mk1 on the photo album. I also acquired two IOR rating 
certificates for my boat among the ship's papers aboard when I bought her. Both 
the 2/76 and 2/82 IOR ratings specify a beam of 11'6", which is consistent. 
(The IOR certificates also list the waterline beam to be 10'5", and that is 
pretty reasonable considering that the 38 has a pronounced tumblehome, with the 
widest part of the hull about 12 to 18" above the waterline.) An article from 
the November 1975 issue of Yacht Racing magazine describes the 38 as a "One 
Tonner with a comfortable interior" and describes how a 38 was optimized for 
the 1975 One Ton Worlds. The article lists the beam as 11'6".

   

  Now the  brochures on the Photo Album, and a price list/spec sheet among my 
ship's papers that is dated 9/13/1976, show the beam of a 38 to be 12'0''. That 
is what is in the data for the PHRF base ratings of both the Mk1 and Mk2.

   

  I also looked at the Photo Album brochures for the early Landfall 38 - the 
version with the fixed aluminum portlights rather than the glued in portlights. 
The brochures say the hull is the same as the "racing" 38 and most of the 
dimensions correspond  - except the beam of the Landfall is listed as 12'3". 
Now that is consistent with what is shown on the original Carpenter's 
Certificate that was in the build file for my boat.

   

  I recall learning someplace that C&C changed a few bulges and bumps between 
the hulls of the Mk1 and Mk2 to take advantage of the IOR rules. So it is 
possible that the beam of the Mk1 was 11'6", and of the Mk2 at 12'0". I might 
discount the measurement shown on my Carpenter's Certificate; a Landfall might 
be 12'3" and that model was about to go into production soon after my boat was 
built, so the statistic could be in error.

   

  Now my question is not intended to challenge the rating I'll get from NCPHRF. 
It is more of the nature or trying to determine if I have a Mk1 or Mk2, and 
trying to reconcile the inconsistent information.

   

  Does anyone know the break point (HIN and/or build date) between a 38 mk1 and 
38 mk2?

   

  If you have a 38 or LF38, what is your HIN and build date? And what do you 
think the beam of your boat to be?

  PS. Some of you who are Great Lakes racers may be interested in some 
information also in my Ship's Papers. I have a scratch sheet for the 1978 
Labatt's 100 race that my boat was in. Among the 21 boats in the two IOR 
divisions there were 13 C&C's ranging from 30 to 38 feet. (1-30, 6-33, 1-35, 
1-36, 4-38) I'm impressed that 2/3 of the boats racing were C&Cs. Speaks pretty 
highly of the heritage of our boats.

  I'm not there, so I can't see it, but most plastic dinghies are made from 
rotomolded polyethylene or polypropylene. Walker Bay boats are made from 
UV-stable polypropylene. ABS is a very unlikely material. You can test it to 
see by dripping pure methylene chloride on the dinghy. If it is one of the poly 
materials it will evaporate without leaving a mark. If it is ABS it will etch 
the material and make it briefly sticky. ABS is glueable using a solvent-based 
chemical, or if prepared right, with epoxy. If it is ABS I would use a 
methacrylate adhesive for maximum strength (Plexus is one brand; small amounts 
are available as Devcon Plastic Welder). 
  Polyethylene and polypropylene are generally considered non-glueable since 
nothing sticks to them. The most promising route to home repair would be with 
WEST System G-Flex, combined with corona treatment. See their literature for 
the full story. I give that approach about a 10% chance of working.
  Any decent plastics shop should be able to heat-weld a repair if you can get 
the dinghy to them. Done right, that will give you a 100% chance of working.
