Wow!!! Love the
mass input on “Sam & Vee’s” brothers and sisters! However the tread
starting to go into concaves, which happens to be what’s going on with my get ‘em
wet boards.
The 1973 plan is
where I started and it evolved as how the flow begins. I know nothing of the
current concepts, except this summer I ran across a “Procter” stick and Holy
Shit! He’s thinking the same!
Educate my old ass
fast I got 3 blanks roughed in and “I needs to know” (Dirty Harry).
Hope this helps - I searched through a couple hundred online pics to find these 3, the last is the best. When I made my bonzer a few years back, I went through the surfy-surfy blog and studied every bonzer picture there.
This is a Bonzer I finished last month. Unfortunately, with all the glue lines you can’t see the concaves that well. Seems that the Cambell Bros. put a second concave near the rail where the fins sit. At an angle pointed toward the nose. Mine just has a double concave from the fins in. Pretty flat out near the rail. Made this one too small for myself. I’m gunna make me one next. The gun has the same set-up.
I met Ben Shipman at the beach way back in 2004...he was really into Bonzers...Twinzers too....I never really understood his designs.....I'm here today to keep the torch going...Ben is gone now....but his Stoke is alive! Try this link
The center Vee is big and deep. The side fins are part of the concave...it doesn't really work with side boxes. The concave extends past the fins...the E-Wing is right there...see it !!!!! Shipman forced me to study the design. Look at Cambell Brothers, Eaton and Surfy Surfy....Gary Hannel......and guess what? Swaylock's Brother ACE is a bonzer shaper!
A long time ago one of my neighbors brought me a broken board he had retrieved from the jetty in Oxnard. It was one of the early Campbell Bros Bonzers and had the triangular sidebites with deep dual concaves.
The guy asked me to make a couple of them - one for himself and one for his friend. I didn't want to copy so much as be 'inspired' by the design. This was before the magazine article and before the Campbell brothers had hooked up with Bing/Eaton/Ace.
I shaped a more subtle version of the concaves and shrunk the side fins a bit as well as rounding them off. I don't have any photos of those boards but have seen a board here that was very similar. I have since noticed that even most of the boards that Duncan Campbell is doing lately are more subtle - some have barely perceptable concaves compared to the originals.
Anyway, here is a photo of the tail of a board that is very close to those boards I did around 1972(?) My apologies to the shaper whose name I don't remember. It is a subtle version of the Campbell Bros concepts - dual concaves with 'mini-keel' sidebites...

Love seeing everyone elses. Love the elevated wing versions, I often look at the boats next to my house and see they have similar wing type hulls on the edges.
