Expedition Wherry Hull Sanded and Taped

The hull has now been sanded on the outside and is looking good to go. The thickened epoxy around the bow has been nicely shaped. 


 

The CLC Expedition Wherry manual has you fiberglass the inside of the hull before the outside, and they have you add fiberglass tape to the outside keel after you fiberglass the outside. They have the tape on the outside layer. 

I'm switching it all around and doing those things in reverse order. It just makes more sense to me. Here is what I'm doing:

1. I'm adding the keel tape first. The tape is intended to be an extra guard against rocks and dragging on the beach and such. The idea is that if it wears away that you can epoxy on another strip of tape in the future. I agree, but there is no reason that you must SEE the tape. Even the CLC manual has you sand the hull smooth, and so the tape would somewhat disappear anyway. However, putting the tape under the main fiberglass layer helps to hide it more. It also acts as a way to help hold the bow and panels together for the time being. You can always still add future tape if needed. 

I installed the tape by first painting on epoxy about an inch and a half on each side of the keel from the bow to where the skeg will be installed. 

Then I placed the tape over the epoxy. The epoxy helps to keep the tape from sliding while you wet it out. I used my gloved hands to press the tape as best I could into the epoxy. 

I then wetted out the tape with additional epoxy. The tape along the curve of the bow tended to buckle a bit, but that is easily fixed. Once all wetted out, take your GLOVED hands and starting from the front, gently pull and smooth the tape aftward and downward. The wetted-out tape will conform to the shape of the bow. You'll see that you then have to continue this pulling and smoothing all the way to the end of the tape. 

This pulling and smoothing also spreads the epoxy out from the tape, essentially squeegeeing the tape a bit. This is good! You do not want the tape to float over the wood. Instead you want it to tightly conform to the hull shape. 

Today I will scrape and sand the tape in preparation for the entire outside to be glassed. 



2. I'm fiberglassing the outside of the hull before the inside. If I were a first-time builder, fiberglassing the outside (convex) side is much easier than the tricky concave bits. Secondly, this will give the hull a huge amount of added support while the inside is glassed. There's no reason that I can see to glass the inside first. Let's get it done. 

Here's how the seams look now. 



More later,

Aloha!

The Rogue Manual

I've posted about this earlier, but thought it might be good to post it again for anyone who may be interested. I've started to write a manual of tips and tricks for Pygmy solo kayak builders. It covers the taping method, so that your boat doesn't have hundreds of holes all over it. I'm on version 2 now. Version 2 covers several other tips and tricks from myself and from others as collected over time. ATTENTION : Use the manual at your own risk! The only person responsible for any mistakes or problems with the building of your boat is you. Always use the official Pygmy manual that came with your kit. Only do those tips and tricks that make sense to you. If something in the manual doesn't sound right to you, then don't do it! Neither I, nor Pygmy Boats, nor anyone else except YOU is responsible for the safety of your boat and the quality of your build. It's in very rough draft form right now, but if you'd like to read it, please send a $10 donat...

Annapolis Wherry Hull Painted

If you haven't yet, please read my previous post regarding amine blush and primers.  After thoroughly washing the hull with water, and then priming, I was now ready for top coating.  I used Interlux Toplac Plus in Matterhorn White. What a great paint! OMG... this stuff seems to have magical properties! I've never used a paint that does not sag or run, even on vertical hull sides.  Of course, you have to roll on a light coat with a foam roller, but even with a thin coat like that, most paints would still have runs. This one doesn't! And you don't need to tip it either! Just roll it on and walk away.  It gets better too... you don't have to sand after each coat! As long as you roll on a second coat after 16 hours but before 3 days, you don't have to sand. Nice! I did three coats in three days with no sanding between coats. There's a slight bit of orange peel, but most of the surface issues are due to my poor surface prep instead of orange peel. To be honest, ...

Waterlog Surfboard Build, Part 2

 Since my last post I've made a lot of progress.   I've completed the rails and the landing strips.  Here is the chine log being epoxied in. By the way, I'm using epoxy for much of this. I ended up using Titebond III for most of the rails because they didn't have a lot of force on them and I could get them clamped down quickly (Titebond III sets quickly). But for anything that has any stress on it, I'm using WEST System epoxy that I have left over.   The nose strips had to be steamed. Read the manual for how to do this. It works well enough.  For the landing strips (the 'lands'), I'm doing the "alternative" method that is shown in one of Grain's tutorial videos . I'm running the outside one out the ends. It worked out well and I'd definitely recommend you do it instead of the convoluted approach they say in their manual.  I would expect that at some point in the future that they make this the primary way to do it and change their m...
