I assume the shaft is on an outdrive or an outboard.
The main problem is that a 1.25" spline shaft may have a hollow core of maybe 0.8". The keyed shaft would then have to have a diameter of no more...
Before you get too far, there is some important terminology. Rigid is a theoretical absolute where a material does not deform regardless of the...
For lengthening the stations can be reused, except that the first and last may need to be re-faired.
Polyboard may not adhere properly to resin, in which case it is not good as a core. You may get a mediocre bond at best and will likely...
If the structure is adequate, the next question is whether you are cruising or racing. Overbuilt is actually under engineered.
I think the main problem you face is the hull/deck structure. A taller mast will generate much higher tension in the standing rig. Also, the...
Are you racing or cruising?
A pirogue is not a yacht so the finish can be mid-rough. Simply grind a taper and an area about 3" around the hole. Then duct tape the hole from...
It would work with similar designs. Otherwise, you could be comparing a scow to a more conventional hull and get the same value.
I sent you that information. Just fill in the form.
The Department of Natural Resources will issue you a home built HIN. Fill the following forms: https://dnr.maryland.gov/Documents/B104.pdf...
You can market them as a kayak withoug legal repercussions. ABYC has a set of standards often used by the USCG, but don't have the force of law...
I am not familiar with that product, but sounds really good. On hot days we give the dump trucks 55 minutes from loading the concrete to dropping...
In Wisconsin the tie-bars and dowels at the cut joints are all epoxy coated. It is a requirement by the State. However, each County can vary...
The displacement is the sum of everything. It includes hull, decks, machinery, fuel, water, supplies, cargo, passengers, etc. The block...
Epoxy coated rebar is commonly used in road and bridge construction. However, it can't be bent too much or the coating fails. Also, after...
That type of rebar can't be bent to shape. It would be extremely expensive to manufacture bars to the shape of a hull.
If you are using epoxy with fiberglass sized for polyester/vinylester, it will be hard to wet. Sizing is supposed to be dissolved by the styrene.
By localized I mean deflection from local loads like blocking at a drydock.
