951.0. "Adding a Rubrail" by CASV05::THOMAS_E (short!!) Tue Aug 16 1988 12:12

    Our topsides took a bit of a beating earlier this year when some
    of the moorings in our anchorage shifted around. As a result of
    this I'm planning on putting a rubrail. Your comments on my plans
    will be appreciated.
    
    Material - Oak. 
    
    Shape - 1" X 1" or 1" on the outside tapering to a 11/2" base.
    Outside corners will of course be rounded.
    
    Scarf joints with epoxy and screws.
    
    Through bolted with stainless or bronze and plugged.
    
    Set in 3M's 5200.
    
    Epoxy over the wood and then one of the two part paints on the epoxy.
    
    Placement - (comments especially appreciated here!! :-)) It will
    be 2-3" below the present deck line. This way it should follow the
    sheer and fit right in.
    
    Whaddaya think?

Good idea. After nine years the rubrail on our boat has a few minor
dings and a major gouge. Our rubrail is actually foam cored fiberglass
about two inches wide and about an inch high. Bolted to this is a 3/4 x
1-1/2 inch teak strip. The rail does need to extend from the hull a ways
to provide good protection. Based on my experience, I'd suggest one of
two things. Either use teak (oiled) for the rubrail or screw a metal
strip (either stainless or bronze) to the outer face of the rubrail. If
you just paint the rubrail, you'll have to repaint promptly every time
you bang the rail against something. When I put the major gouge in my
rubrail I simply sanded the gouge smooth and faired it into the
undamaged rail. The hollow can't be seen from 10 feet away. If there'd
been a metal protective strip, I'd have had to replace a section of the
strip. Our rubrail is 8 or 10 inches below the sheer at the widest part 
of the hull (which has some tumblehome).

951.2Oak vs TequeBIGALO::HALL_MERRILLTue Aug 16 1988 13:307
    I agree with the teak instead of oak.  Oak tends to splinter and
    check after a while of exposure.  Covering it with epoxy generally
    doesn't solve much because oak doesn't bond well even when super
    dry.  The metal strip is ok for you but will have a way of turning
    a minor bump with another boat into an insurance claim.  I'd go
    with mahogany or teak, with the plugged bolts and 5200.

951.3Study the proportionsEXPERT::SPENCERJohn SpencerWed Aug 17 1988 10:1223
As Alan suggests, you probably want a rub rail to stand proud of the hull 
and all other trim.  Unless you have a lot of topside flare at decklevel, 
or a toerail/caprail that projects quite a way, it should be possible to 
add a rubstrake that will hit a vertical surface before any other part of 
the boat does.

Also, look carefully at your sheerline -- deck or bulwark -- and if you 
have a wale or walestripe, carefully measure how the width between those 
changes.  Chances are you may want to increase the distance below the 
toerail/caprail *slightly* at the ends (more at the bow than stern 
usually) to preserve the balanced proportions.  This even applies to 
comparing the sheer and waterline if your boat has a noticeable sheer.

Check out the magazine illustrations, especially the sideview renderings 
which don't have any photographic distortions to hide the fact.  Were I to 
consider do this to a boat of my own, I'd get a sideview in several 
copies, as large a scale as practical (1:10 perhaps) and sketch in various 
options to see what looks best.  You really can affect your vessel's 
appearance with such an addition, and so it might as well be to the 
better!

951.4CASV05::THOMAS_Eshort!!Wed Aug 17 1988 11:1214
    The boat's a Sea Sprite 23. She's designed by Alberg so she's got
    a pretty sheer that I dont want to ruin. I'll give the Ryder folks
    a call to see if they can provide some side views. The boat has a cove
    stripe that should give some clues as to how to place a rubstrake.
    Actually, the rubstrake may have to go over the cove stripe to avoid
    a "busy" look. Freeboard at the cockpit is close to 2' so there's not
    a lot of room to play with. Fortunately my wife has a good design
    eye and will make sure I don't ruin Zendia's lines.
    
    Thanks,

951.5Good ideaEXPERT::SPENCERJohn SpencerWed Aug 17 1988 14:447
Placing the rubstrake right over the cove stripe is an excellent idea, for 
the reasons you mention.  It certainly solves the positioning dilemma, and 
even gives you a little pocket to hold plenty of bedding compound around 
the screw or bolt shafts.
