True,
Not to scale, just a rough sketch of a concept.
This is the same way that Flotsam was designed, then talked about, and then built on the fly,
using my body and a small tape measure to add numbers to the rough sketch.
Then using 5"x8" card stock, stacked up, the sketch was redrawn, pressing down, leaving an imprint,
much like carbon paper but no ink.
With that impression on a clean card, any changes in design could be drawn in and the process repeated
until the final shape or design is there. Any features we saw at a boat show, or in other pictures, could be added this way.
Very primitive perhaps. But i have been designing things like this for years. Not just boats. A very low cost way.
And one I enjoy. I see the very nice Auto Cad pics that many use now. I choose to remain old school, and primitive.
Back to the 'tri project.
The hull shape is 15' x 6'. This allows about 2' or a bit more for the center console, and a bit less for the walk arounds.
The 3 seats will be inline. The helm in the middle, the front to have some storage or a small cooler, and in front of any windscreen.
The rear to hide the porta. A nessesity when spending a few hours fishing with my wife. There also needs to be some
other form of movable seat to use when I'm hoggin' all 3 inline seats napping.
Yes, very tight, not much extra room. But just enough for us. We are average sized. Not meant to be an overnight,
or to take a crowd out boating.
As far as windage, top speed is not expeced to be more than 15 mph or 20 at most. Just above a plane. And not very often.
As far as top heavy, I have been considering that from the start. That is a good chalenge to build something
that is light enough but still strong enough to withstand the trip down the road on the trailer.
I did build a top, tall enough to stand under, for our 16' Invader, using aluminum for a frame, and glass covered
1/4" ply for a cover, and that was quite heavy but made no noticable difference in performance. We did use that during rainy days.
This top will need to be lighter. The tri hull shape has some built in stability.
Thank you for your interest and comments. I do welcome any comments, good or not, as for sure someone else might
notice things I would miss.
I will work this week to make a few more line drawings to help show what I am hoping to build.
