HWS - Does interior need glass?

I’m sorry if this is a really basic question.

But trying to see if there is a way to get away with not glassing the interior of a HWS.

Can it be done with more ribs and/or stronger deck panels and just glass job on exterior?

Or any other way?

Thanks

I thought most builders do not glass the inside. The thought is that choosing a rot resistant wood and installing a vent hole will allow minor water intrusion without damaging the inside. You can also just use a water seal coating on the internal framing to keep it from rotting out.

If you are glassing for strength, it’s probably more effective to double glass the outside instead.

Ah nice BillyBob.

My thinking is I want to make a HWS but want to send it out to glass.

I’ll keep reading

Thanks

the above poster nailed it.

I spaced my ribs something like 8", sanded my deck down to less than 1/4"

and only used 1 layer of 4oz cloth on the deck and hull and the thing is

a beast.

glassing the inside is dead weight unless you’re planning on total system

failure and expecting copious amounts of water penetration.

brother, DO NOT send your board out to be glassed.

it seems daunting…there’s so many things that you think can go wrong

but keep in mind:

  1. it’s cheaper to do it yourself

  2. “when in doubt, sand it out” … you can nearly always completely erase

eff ups by sanding it down and taking a mulligan.

  1. once you discover how easy this board was to make, you’re going to want

to make more so learning to glass has future benefits.

  1. your first board will come out all wonky and eventually you’ll make the most

perfect and beautiful board in the world that would justify the expense of

shopping out the glass job to a pro.

Hey thanks.

Was dreading the whole glass inside thing.

I’ve been glassing EPS for a couple years. But needed to stop. I’m not setup properly to handle it.

Don’t have a good space for it right now.

word, makes sense.

where you at in BK?

I had a friend that I used to visit right by Atlantic and Clinton.

Nice…

I’m right down the street.

Got really lucky and found an apartment that I’m able to work out of.

Just don’t think Laying out epoxy and sanding it is the best idea.

Oh well.

At least I got to learn the process.

My last couple came out sooo good.

Glassing the inside creates a “sandwich” of wood…Far stronger than going without…

A dry lam is the key to keeping the weight down…it’s all a balancing act…More ribs, no glass…Fewer ribs and glassed…

Then again it depends on how you are building the board, and how you surf…

i agree totally with this post. i glassed my first board on the inside and it came out a total tank.

my second board i skipped the inside glass and kept the decking at 4mm. heaps lighter and seems to be strong enough.

paul is exactly right also. if your going super thin on your decking, sandwiching it makes it super strong.

i spaced my ribs at 8" and used cedar. if it does manage to get a little wet, it never rots. good stuff to use…

only glass the inside of your skins if you are using very thin skins. If you are looking for water protection, you can spray the inside of your skin and your framework with thinned epoxy.

If you are using 1/4" ply for your deck you don’t need glass on the inside. If you are gluing up strips to make the deck I would say glass the inside. The strips will crack along the seems if there is no glass holding them together on the inside. It doesn’t matter how heavy you glass the outside the seems will still split. If in doubt do a test.

i built my hws with 1/4" skins, using strips of cedar. no glass inside or out. solid as a tank.
