Re: [PSUBS-MAILIST] OSS spec sheet
A one place K-350 may be about 3500 pounds (sorry but I don't have a
conversions here at this time) but the two place with it's added 24 inched
hull length displaces 4400 pounds.
The towing capacity of a 3/4 ton pickup truck may be 10,000 pounds but it's
not that easy. At towing it's maximum capacity, a truck isn't that stable
on the highway. Believe me. In my neighborhood, I'm known as the "Over
Load King."
I unloaded the steel and running gear for my K-350 trailer a few days ago.
My trailer will have a 7000 pound capacity including it's own weight. The
sub will weigh 4400. The trailer will weigh 1000 pounds leaving 1600 pounds
excess capacity for extras with a little margin. The materials for it total
up to just under $2000 US. That's everything including lights and tires.
Sitting in the seat of a K-350 isn't really all that tight! I would say it
would be nice to have an extra six inches of hull diameter max. Considering
the cost of every inch, that's as far as I'd go with making it larger. At
most, I'd start with a K-350 hull and scale the whole thing up by 1.17
Maybe it's time to get a better idea of what is the real upper end cost to
a sub that will likely get built. That's what held me back for the last
fifteen years pondering the project. I've never been involved in a project
yet that it didn't all boil down the bottom line. TOTAL COST
I agree with Ian, to much to do and to inconvenient launching the sub would
mean it wouldn't get launched as much. One thought about the removable drop
weights is towing would be improved if the weight could be loaded in the
truck rather then stay on the trailer. In my opinion they would have to be
on the sub at launch though. What's the sense of subbing if you have to go
skin diving first?
