Re: The man/water interface...swim ladders

While I am typing... The horizontal braces on the stern arch thing offer much less strengthening than a pair of diagonals would provide. So if you are looking to clean up air flow I'd toss those and put in diagonal wires instead. Maybe with one horizontal strut to take the compression. (And the outboard).

This has been on my mind also. The horizontal braces do a few things besides the outboard so they stay.

I've been in up to about 35 knots beating and had no issue with the tower. If I did have an issue, or was expecting worse conditions I would run some bracing, much as you suggest, using nylon tie downs. I'm going to fool with that shortly to get a sense of how much that actually stiffens the rig.

I found this other thread with some additional options.

That looks awfully cold to me.

Since retirement I haven't used a full fledged CAD program.

An iPad, iDesign and a stumpy finger for a quick sketch while kicked back in my bunk.

iDesign is actually a pretty good little CAD app.

Looking for another pretty place to work on the boat.

Actually Apple stuff pretty well sweeps the floor when it comes to the visuals. I should have realised it would be something Apple related. My little Windoze drawings look awfully basic.

Re: The man/water interface...swim ladders

I use TurboCAD on a PC. Buy older version off eBay, but even most recent versions are pretty reasonable.

Performs well with a very intuitive interface.

Re: The man/water interface...swim ladders

We went over to lowes to see what they had and came away with this. Aluminum ramps to load an ATV into a pick up. 12" wide by 77" long, and curved nicely.

Here is a first order approximation....ignore the ongoing cosmetic repairs...
