How Richard Fraser built his Arthur Piver
Mariner 25' Trimaran in the 1960's - a
treasured photo adventure

    In July of 1965, Richard started to built his first boat. It was an Arthur
    Piver designed Trimaran sail boat that was called a "Mariner" with a
    length of 25 feet and beam of 15 feet.

    Richard is fortunate that he kept a photo log of the progress that was
    made over the four year building period. And, yes I (Richard) said it
    took four years......for those who want to build a boat. Most quit before
    that time, but for those who preserver, the time is rewarding. Richard
    also credits the Kodak Film Company for manufacturing a good
    quality photo film that was able to keep it's colors somewhat fresh
    over these past 47 years. And, for the good little camera that took the
    pictures and the persistent use of the Kodak printing paper which
    was used. Without these things, the photos probably would have
    been lost.

    The building address was 834 N. Francisca Avenue in Redondo
    Beach, Ca. Other well known builders used this address as well. After
    47 years and now at the age of 75 years, Richard is collecting his
    memory of the facts and ingenuity that transpired back in those days.
    This location is being completely renovated today. Review some of
    the photos for a historical reference because the address is no longer

    These photos bring back great memories, not only of the boat, but the
    experienced people who helped when you had a question or two or
    three or four.

To begin with, the trimaran was built using quality ABX (smooth, good both sides) exterior fir  plywood
skins held in place by using water mixed powdered urea/formaldehyde resin glue (available at that time)
and boat bronze ring nails......lots of them, with Polyester resin and 6 ounce glass cloth sheathing. The
Epoxys were not around at that time. Epoxy paints were just introduced, but we used good quality
topside and below waterline anti-fouling yacht paints. I cannot remember the brand name but it was not
Interlux, which was also available then. All fir plywood skins were scarfed together...not butted, providing
the strongest 100% through water proof joint bond.

Most of the boat frames were fabricated at home per Pivers drawings. That saved a lot of time so it was
easy to fit them onto the building jigs that are shown in the photos. Their shapes proved to be accurate
and fair when we started installing the chines and stringers. Arthur, or who ever did Pivers drawings did
a good job.

The time line given by the photo dates gives some information as how long each portion of the building
took. One must remember though, that work was generally done on weekends and holidays. Richard still
worked in the aircraft and Aerospace Industry full time as a Laboratory Design Engineer at that time.

    Photo Number 2 - Fitting all the
    frames and bulkheads in place.
    Richard was totally unaware at
    this point in time that it would be
    4 years before this boat would
    be finished.
    Photo Number 3 - More fitting of
    frames and bulkheads. Note the
    chalk line just above the white
    painted lower part of the building
    jig. This allowed for straight
    hull centerlines.
    Photo Number 4 - More fitting of
    frames and bulkheads. Bow view.
    Photo Number 5 - Centerboard
    trunk fabricated and fitted in
    place. Photo was taken
    Aug. 1965.
