Mark Evans

Looking for some pictures for a customer, I stumbled onto these. Mark Evans with his tri Tachyon at Kelly’s Landing here in Seattle, in 1977 or 1978. Mark was a sort of guru for a generation of PNW multihull builders and sailors. Design is a Sally Lightfoot 26.
One of the best sails I ever had was with Mark. We were sailing in a snowstorm here on Lake Union. December ’78. Utterly silent.

 

More from Hiiumaa Island

I have mixed feelings about these pictures. I just got them from the builders of my 46′ power cat design in Estonia. They took my 3D model and hired a kid to finish it up, as he works for much less than I do. The earth is indeed flat. The kid did good work. I get to see it on the water at the Helsinki Boat Show I hear.

Teardrop Trailer

A few years back a multihull sailor friend wanted to face the recession proactively by building teardrop trailers.  Its really a pretty good idea to use boatbuilding technology to do that.  I designed one using a sandwich of 3mm plywood faces with 3/4″ pvc core.  Biaxial corners and glass cloth on the exterior and wear surfaces.  I recall he built it bright.  It is light, strong, quiet and insulated.  He had a budget of one hour design time, so the 3D model is pretty spare.  A little time spent scaling the  wood grain and adding some homey details like windows would have helped the cuteness.  There it is.

Charter Cat Rolls Over in Florida

A daycharter cat in Florida rolled over from a wave during thanskgiving. Notes thanks to Earl Dame. http://articles.sun-sentinel.com/2012-11-23/news/fl-pompano-dive-boat-folo-20121123_1_rough-seas-hillsboro-inlet-high-seas

Look how narrow overall it is for its 45′ length. Only 14.4′. It looks like a powercat designed by guys who were chopper-gunning truck bed covers just a few years ago. Not only do the sum of the hull widths look like they are about half the beam overall, it has planing speedboat bows for displacement boat speeds. No wonder it took twice 225 hp to go 20 knots! A 45′ cat that I or Roger (Hatfield) or even Gino would design would do that 20 knots with about 80 hp per side. Certainly not over 100 hp per side.
The narrow overall beam shouts beginner to me.

New Printer

new printer should arrive next week, a Canon iPF765. It seems that it has a screen that carries on discussions with one… “I’m afraid I can’t do that, Dave…” It might take a couple of days to sort out how to run it. One issue is it will not accept any input from LPT1. I do have a few thousand legacy Generic CADD files (still best 2D  CADD program ever developed). Does JD or anyone have any thoughts on getting LPT1 files into USB? Only thought I have is to stop them off at Visual Cadd on the way, then plot from there on USB.
