[Rhodes22-list] Hull strengthening

[Graham Stewart]

Lou plans to strengthen his hull and I was considering the same since I have
the interior of my 76 completely stripped out. It seems like the opportune
time to do so if it is worthwhile and if I had some idea of what was needed.
It would only be feasible to do the main cabin and possible the forward area
if I remove the foam. I am not sure how the foam is held in place and how I
would reattach it.

Has anyone done this or do they have any technical thoughts about how many
layers of fibreglass should be added? Is it really worth the effort?

The reasons I am thinking about this is that I understand that later boats
have a heavier layup and I assume there was a good reason for that and
because the hull seems overly flexible and has taken a dent where the
forward starboard strut of the trailer presses on the hull. I jacked the
boat up about 2 years ago and most of the dent has come out, but I thought
that some strengthening - perhaps with strengthening ribs of some sort might
be prevent the impression from forming again when the boat is lowered back
on the bunk.

 I would value thought from those who might know more about whether and/or
how to proceed.

James,

I renovated my '81 centerboard trunk and mechanism.  While its a totally
different design than what you have in front of you, I recommend trying to
re create what Stan had in that era of R22s.   Try to create a two piece 
(cap and flange ) system with a recessed "V" inside your trunk to hold the
pivot pin.
If for some reason you have no access to pics of this, I can supply some
directly to you.

I have documented my renovation in the Owner's site in the section under
technical details I believe.
Roger Pihlaja did most of the writing on the structural details of the
cement and glass work. I followed his online instructions and did the job
alone. I took one year of hard labor but it was worth it.  Since then I ve
re lined my centerboard cap and flange with Garolite (1/4") to make a firm
seal.  I have not had any issues since but am very curious to know how far
you took your restoration of the hull.

I plan to add stringers under my cockpit and remove the fwd foam to also
strengthen the glass from inside my boat.  I had a major issue with boat pox
which resulted in small hull leaks.

Good luck with your endeavor.
