Wolstenholme Yacht Design

>>> Wolstenholme Yacht Design

Another designer with some neat designs…

Andrew Wolstenholme has produced a wide variety of designs ranging from award winning production powerboats to classic launches and traditional craft for sail and oar, with several thousand examples of these boats to be seen around the world.

I especially liked the Wheelyboat Mk III – it looks like a miniature landing craft and is designed for use by wheelchair bound fishermen on European rivers and lakes… neat idea and a great way of letting a mobility impared person continue to enjoy the water!

His 57-60′ Cruising Barge design are some gorgeous craft… I love that European/Dutch Barge look!

Sheer clamp layer 2

Dane and I spent a bit and got the second layer of sheer clamp on port and starboard. Actually went on easier than I expected. Nearly messed up forgetting to clean up some of the epoxy drips from the first layer, but went back over it with the hand planer and a hammer and chisel for a few nooks and crannies. Actually went really fast.

It was one of those jobs that I’m glad is done and worked well, but there really isn’t much to "show"… just another board running right where one already was. I do have one issue that I will have to deal with somehow later… one of the notches for the sheer clamp on Frame B (at the bow) wasn’t deep enough. I didn’t notice it and the first layer was all attached and glued in. Now with the second layer on there, the second layer sticks out proud of the hull line. Its fine on one side, but about 1/4" off on the other. Guess I’ll have to plane it down fair to keep things symetrical.

Dane also got to learn about surface area when he asked an very astute question… we had a little backing block that got glued onto the sheer clamp… he commented that it was part of the boat now. I stated that it would probably come off it I hit it with a hammer. He was immediately concerned with "if that will come off when you hit it with a hammer, what happens to the entire boat if a big wave hits it". Good question… another learning experience in explaining how a very small surface had the glue on it versus the entire structure, etc.

Glendinning – Marine and RV products

>>> Glendinning – Marine and RV products

Another source of marine and RV stuff… got the pointer from a Ship Shape TV episode (sometimes really interesting… sometimes all fluff).

Their marine line is mostly shore power and water line "handlers"… powered devices to neatly stow your cables, etc. and also control boxes/cables for engine/transmission type controls. Look nice on TV, anyhow πŸ™‚


Glendinning has been bringing you the finest quality, innovative products for both the marine and rv industries since 1972. Our reputation for quality and service is second to none!

Sheer clamps – part 2

Got the next layer of sheer clamps scarfed and glued up… another set of long boards running across my garage. Dane is getting to be quite the expert at helping me get them straight… he sits at one end and sights down the board, telling me which way to move things. We find that eyeballs can be just as accurate if not more than trying to use a straightedge. After getting them lined up, he comes and acts as a mobile weight (he stands on them) and we fasten them for gluing.

Did wind up getting the epoxy mixed thicker than I normally have used… KB of Tubby Tug fame recommends getting it thick… I hadn’t really intended this to be the experiment, but it wound up that way, so we went with it. We’ll see how it comes out.

Boat Bits

>>> Boat Bits

This is a neat blog with a slogan of “A sailing blog : Random thoughts and rants on boat design, boat building, and other boat bits…”… a bit more of a sailing bent than I have, but lots of alternative energy, etc.

Not to mention, he was kind enough to link to Craft A Craft in a recent post. He found the Windbelt post of interest and has found a link to a more detailed web page for Humdinger Wind Energy, LLC.

Windbelt – Cheap Generator Alternative

This Popular Mechanics blurb shows a really neat design for getting electricity from wind. It’s designed for low wind speed, low cost applications, but looks to me like it could be really nice on a boat. Low cost (always good), low wind requirements, I would expect it to be fairly quiet, and no moving blades to hit you in the head.

Tubby Tug – Abby’s Lil Tug

>>> Tubby Tug – Abby’s Lil Tug

KB’s recent comment about his Lil Woody leads us to his new project, a Glen-L designed Tubby Tug for his daughter. These are cute little boats that I looked at in the past… I think it would be a great "father/child" project for those wanting something a little smaller than the project I bit off πŸ™‚

KB has a nicely detailed set of web sites, and the pictures and commentary are great learning tools. I appreciated his opinions of epoxy thickening… that’s a subject that I haven’t found enough information on yet πŸ™‚

A good rule of thumbs when mixing epoxy and silica is that if you wonder if it is thick enough – it isn’t. It will run and sag if not thick enough.

One website said to mix the epoxy and silica to a consistency of peanut butter. BUT, is that warm peanut butter or peanut butter that you just pulled out of the fridge? Is it the consistency of Skippy or Peter Pan? – October 4, 2007

KB’s planning for electric drive, so he’s fitting in here more and more.

Thanks, KB for your post and great web site! By the way, I’m well aware of those little one’s holding you to your promise to build a boat…. been there and doing that πŸ™‚

Look at those lines…

This first picture shows the first sheer clamp to be installed, although its hard to see from this angle. What is very apparent is the inner keel that I got on the other day.

This later picture shows the sheer… a nice curved board closest to the ground.  Started the day cleaning up the notches for the sheer clamp. Biggest hassle here was that some of the frame supports that hold the frames off the stongback were in the way… If you are ever doing this, try to plan that aspect better πŸ™‚

I was impressed with how easily it went on after we found the best method… start at the point of the lowest freeboard (highest from ground) which happens to be Frame G. Attach there and have Dane use his newfound knowledge of the leverage you get pulling on the end of a long board and I work my way down the boat. Went right along.

This was a good example where this has been a good chance to work with my little boy, enjoy the time together, and teach things all at the same time. I enjoy the boatbuilding, but these “teachable moments” as they call them are a real added bonus.

Lastly dropped by the store while we were out doing some of the Saturday errands and got the 1×3’s for the next layer of the sheer clamp and a 1x8x12 to cut the inner stem from.
