Printing your own NOAA Charts

Using free software and you can download edit and print free NOAA charts just like the paper ones are are all familiar with. I wish I had know about this before I did it by scanning a paper chart!

Repowering your Sailboat

If your present engine is always hard to start, has constantly smoky exhaust, burns or leaks a lot of oil, is low on power, has coolant or water in the oil, or parts are difficult or expensive to acquire, repowering solves ALL these problems.

Amsteel to StaSet Splice

Splice of 1/8 inch Amsteel-Blue to 1/4 inch Sta-Set is shown. This is ideal for the halyard of a small boat and is also a scale model for a 3/16 Amsteel to 3/8 Sta-Set splice, which would be good for a 36 foot boat. I have tested this splice to the breaking strength of the StaSet and the splice holds fine.

Jib Twing

A Jibsheet Twing is sometimes called a Jib Sheet Downhaul. It is used instead of moving the jib car when you sail off the wind. At least that is what I do and it is so much easier than trying to move the car even if you have lines to move the car. This article also discusses sail trim for off the wind and how a twing can help get good trim.

Bonding your boat

The topic of bonding on boats has more myth and misinformation than most any other topic. This article tries to present the reasons to and not to bond so you can decide what to do.

Lightning on a Sailboat

As part of a project on bonding on boats, I have put together this reference to various articles on lightning.

Humidity Below Deck

Follow this blog of my struggles with mold and humidity or jump to the end where the data is in. The conclusion is keep all the compartments open an inch, use a StorDry to provide low level heat that promotes air circulation and get lots of air moving through. A couple of nice humidity calculators are included.

Low cost High Tech Halyard

For about $75 I have a 100 ft long light weight easy on the hands halyard to replace the wire main halyard. The trick is the choice of cover material and the splice while keeping the strength thought the entire length.

Mainsheet Systems

Papoose has a Double Ended 5:1 Mainsheet System. I explain it as well as show most other popular mainsheet systems in this mainsheet systems page.

Rig Tuning

I have not tried this but it looks like it would be a very accurate way to measure rig tension.

Loos gauge accuracy

They didn't look very accurate to me until I found out that you have to do a little trick not covered in the instructions. Before that, I got readings at mid scale from two new Loos gauges that differed by 26% or more. See my write up. Now my gauge agrees with what I know to be correct from the measurements discussed in the article.

Foot Block Wedge

How to Calculate the Dimensions of a Wedge Pad for a Foot Block Turning Block. I take into account the distances involved and determine the angles and heights of the bad that goes under the turning block to make the leading angles fair.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
