About Us
Doug Jackson SV Seeker Tulsa, OK USA My name is Doug Jackson. I am the ambition and drive behind SV Seeker, but my success comes from knowing a lot of brilliant and skilled people who are drawn together around the sailboat Seeker. SV Seeker is not just a sailboat nor a yacht.

Aluminum Molds
I was working on building support legs for the submarine. This is basically a linier actuator using all-thread rod for a lead screws and common 3/4 inch nuts cast inside of cylinder that will fit inside a 1 1/2 inch pipe.

For SV Seeker we currently plan to carry home built anchors that we can build as needed. Claw Anchor, 176 lbs for $535 Go2Marine has a 176 pound, galvanized, Claw anchor for $535 + shipping. Around $660 with shipping.

Battens
Why Junk Sails? I like Junk sails because they are easy to reef, there are no sail changes, they can be automated in their 2000 year old form without the complications modern furling systems, I think they are beautiful, and the short comings of windward performance and sailing in light airs are not a setback for me…

DIY Snatch Block Mark Hamill, who you can reach via the OrigamiBoats group on Yahoo, designed and build the snatch block below. UHMW plastic would work well in this design. The block is hot dip galvanized after it’s built. A wood lathe or router with a cove bit can be used to cut the notch in the pulley.

Casting
Sometimes we can’t find a part, and fashioning it using the small lathe or pieces of steel just won’t do — so we turn to casting. We’ve made several parts for our vessels; some a necessity and some just for fun. In addition we have melted lead, both for ingots and for the ballast to fill the keels in Seeker.

Casting Propeller Blades
How Ship Propeller Blades are Cast These illustrations from Marine Propellers and Propulsion show how propellers were traditionally molded and cast. Traditional casting was often done using the Randupson process with uses portland cement as a bonding agent. I like the idea, as portland is widely available.

Casting the Capstans or Try try again.
When a toddler stumbles and falls for the fourth time. No body says, “Just give up. You’re a failure”. But by the time we get to high school it’s common. Failure is synonymous with looser, flunkies, stupid, retard. The whole idea of failing at anything is abhorrent.

Companionway Elevator
Seeker’s companionway ladders are just that, real aluminum extension ladders. If you’re going to be a work boat, a couple of 16 foot extension ladders will come in handy. But in addition to the ladders we want to be able to move heavy loads and persons with bad knees or injuries too.

I question myself when I want to add something that I have never seen on a boat. But this one just makes a lot of sense to me, and lugging the 80 pound welder, and plasma cutter, grinders, and steel up and down the companionways has convinced me this is a really good idea.

Controllable Pitch Propeller
Hundested. We Love It!!! Why Controllable Pitch Propeller? The benefits of controllable pitch propellers (CPP) specifically for a sailing/cursing/workboat are remarkable. * The props speed vs. power can be adjusted according to varying cargo loads. * Drag can be reduced or increased to meet the sailing conditions.

Electric power for the various systems I wanted on Seeker was mistakenly high on my list of things to acquire when we decided to build. I soon learned that it rightly deserves a place at the bottom of the list. The technology is constantly improving and the prices for existing technology is constantly falling.

I do wish we had not lost our ability to drink salt water, or breath it for that matter. It was an unfortunate turn in our evolutionary path. And wouldn’t it be very advantageous for sailors to also have a monkey’s tail? So how do we manage to survive on an ocean of poison and avoid drinking our own urine?
