Mailport: Marelon Seacocks

Regarding your recent report on Seacocks (“Beneteau Responds to Seacock Query,” PS August 2018) I owned a 1987 Catalina 30, Mark II. It had four gate valves instead of seacocks. I had them replaced with Forespar Marelon seacocks. Over the next six years that I owned the boat, two handles sheared off while opening or closing them. I lubricated them every year during winter layup. I exercised them regularly during the season. Forespar replaced the handles at no charge but I am not a fan of their seacocks. The boat was always sailed in fresh water, Lake Erie. I currently own a 1998 Beneteau Oceanis 321 and am the captain of a 2013 Beneteau Oceanis 50. I lube the seacocks every winter. Both boats have always sailed in fresh water, Lake Erie. Zero problems with the seacocks.

Tapping Spars

If you are into spars (see PS September 2018), consider that taps are extremely strong but brittle. It is very important to secure your work as rigidly as possible. Use aids to insure both the hole you drill and the tapping process are square to the work. If you can put your work in a vise on a drill press do it. You can then drill the hole square and gently start the tap into the hole at the lowest speed possible gently tightening the tap in the chuck so it will slip when some resistance is felt but the tap gets a start. Finish the hole with a two-handed tap handle exerting equal pressure on each side of the tap driver. In thicker materials (and especially stainless steel), after you have achieved a turn or two, reverse the tap a half-turn to break the cut chips and to clear the cutting side for a new cut. I find using a paste-cutting medium to be cleaner and more effective. Some larger marine stores carry this. I always go down a few numbers (up in size) on the drill index when drilling stainless steel. If you do a lot of drilling and fastening with sheet metal screws or plan to do some drilling-and-tapping, an investment in a “numbered” drill index is money well spent. A 10-32 tap calls for a #21 bit. A 10-24 tap calls for a #25. Be ever so careful, and use a new tap for a part that is very important to you. Broken taps can be very difficult to remove.

True that. A broken tap can be as stubborn as a sheared bolt.


 

Ultra Sonic Testing

Ultra sonic testing (see PS October 2018) is an excellent idea for inspecting metal components, but in my opinion it is much less practical for large area composite inspections, which is a bit like visually inspecting an elephant while looking through a drinking straw. The test instrument’s inspection area is just too small. PS comments about using a phenolic or metal hammer to search for composite delaminations were contradictory relative to the cost of UT testing. Why use a $20 tool to reach a damage-repair decision that might cost tens of thousand of dollars, or a purchase decision for hundreds of thousands of dollars? Wouldn’t infra-red thermography or laser shearography, although much more expensive, be more appropriate for informing those decisions? Again, the inspector’s IR or LS qualifications and familiarity with marine composites are critical. Regardless of the inspection method or equipment used, the inspector’s experience and qualifications are critical, and this bears careful consideration in the DIY context.

We can see how headline to the article (“DIY Materials Testing”) could lead one to believe we were encouraging DIY ultrasonic testing. You are right, the price and training required to operate the equipment would not qualify as a typical DIY project. We’ve begun researching IR and LS inspection for a future report.


 

Steering Wheels, Fully Dressed

I enjoyed your informative article on wrapping the steering wheel with rope [for better grip and ergonomics]. There are a few questions remaining: Where do you source the wrapping line? I’ve tried West Marine. Also, how do you calculate the length of line to purchase? I have a 24-inch diameter wheel on my Ocean Alexander Fly Bridge and you are correct—the wheel is way cold most of the time.

We’ve used a variety of nylon and nylon/polyester braid lines from the hardware store. The last was from Best Deal Hardware, where you can get 100 feet of 1/4-inch braided nylon for about $15. You want some elasticity in the rope, since that is what keeps it snug. Confirm it is nylon. The length required to cover 1 inch diameter wheel is approximately D x 3.14 x 3.14 x 4 = about 80 feet (where D equals the wheel diameter in inches), so use a 100-foot hank. The stretch will reduce the line diameter, but it will also make it longer. Take your time, tightening lightly every few wraps and then very tightly every rung, working in extra turns as needed to keep it gap-free.


 

Combatting Weevils

Regarding your recent PS Advisor on weevils (PS November 2018), I’m not clear if this article is saying all brown rice and grains have eggs or only outside developed countries? It would also be helpful to know if there is any health risk to eating the eggs or larvae?

All grains can contain eggs, even in developed countries; fumigation is quite effective, but often less than 100 percent. Additionally, the infestation can come from outside, after packaging but before purchase; grain weevils are present world-wide as an introduced species and can easily chew through paper or plastic bags. We’ve seen the holes! We did not investigate the health risk, but the editor has eaten plenty of weevils during his cruising days, and he is still mostly sane. Weevils may be distasteful to most people, but are not harmful. In fact, one source suggested weevils can serve as canaries in the coal mine to test for the presence of pesticides. Live weevils that die after dining on your wheat suggests pesticide is still present. Yes, bay leaves are helpful as a repellent, but won’t drive away weevils from grain that is already infested. We tested that too. Finally, and this advice we credit to reader Tom Carroll. If two weevils wind up in your spoonful of grain, and you’ve only the appetite for one, always choose the lesser of two weevils.


 

North Shore Canvas

Regarding your recent PS Advisor, “What to Look For in a Winter Cover,” North Shore Canvas made my Noreaster cover for Tartan 37. It fits like a glove. It is now in its fourth season, and it is still in great shape. I have a painted hull. The previous owner framed and tarped the boat for the first season I owned it. The paint on the hull was really damaged by chafe, and it was a major project to bring it back. The tarp cover seemed pretty tight, but it still chafed the paint.

Shipshape Canvas

We purchased a Hunter 44AC in August of 2016. During the marine survey I asked for recommendations for winter covers. One name and company came out, Jim and Shipshape Canvas. Jim had to measure the boat and I was skeptical about how well it would fit. The cover fit perfectly, was delivered on time and we are extremely happy with the investment. The boat is in the snowbelt of Lake Erie (we measure snowfall events by the foot), and the cover has performed flawlessly. Last winter, we had wind gusts to 60 knots. Several other club members now have Shipshape covers and are as happy as I am. It takes just 90 minutes to install each season, and less than 30 minutes to remove.

Gaffe of the Year

Our late night editing sessions finally caught up with us last month when our Gear of the Year Article proudly claimed that we were the wrong publication to turn to for advice about sailing gear. One day, we might finally laugh about this error.

Comments (1)

This comment is not really meant for publication; however, I've noticed with articles that have two or more comments that often the same comment will be repeated once, twice, or even three times. Having commented on articles a few times myself, it's difficult - if not impossible - to determine if your comment was received. There's no notice after submitting a comment that shows that your comment was received. Maybe your webmaster could somehow add a receipt confirmation after submitted of a comment.
