Joseph Serio of Brooklyn, New York, asks: “What is the best way to check that the shrouds and stays are properly adjusted on my Irwin 40 Mk 11?” Win Fowler replies: Let’s talk about a single-spreader rig. For more spreaders the principles are the same, but the process is a bit trickier. Before you start, make sure the spreader-tip heights bisect

Paul Scott of Coral Gables, Florida, asks:”I just bought a pre-owned boat that came with a fairly new 406 MHz EPIRB. I’ve checked the date on the battery, and it is fine, but when I contacted the FCC to change the registration information, they told me that they don’t handle EPIRB registrations. Where should I go to re-register my unit?”Gordon West

Recently, as part of my work on hybrid propulsion systems, I attended a demonstration where a large-scale lithium battery pack was deliberately pushed past the boundaries of existing experience. The intention was to run the system at 20 kW of output and 160 volts, creating a current flow of around 130 amps. Owing to a miscalculation, when we threw the switch and brought everything on line we

In the April edition of Ask Sail, Nigel Calder asked readers to share ideas on how best to keep their props clean. The Q and A from the magazine sparked a discussion with readers chiming in from all corners of the country.

Dick Hansen of Norwalk, Connecticut, asks:”My new chartplotter is just great and gives me aerial and radar overlays. But when I transmit on VHF Channel 68, a frequency we use a lot in my area, the GPS hiccups, the chartplotter freezes, and it can take about 30 seconds for the system to recover. Everything works fine when I transmit on other channels; it’s just 68 that is

Olene Boyko of Urbanna, Virginia, asks:”On removing the inspection plates on the welded steel water tanks aboard my 48–foot boat, I could see they were painted on the inside with a blue high-gloss rubber-like paint. I also saw quite a bit of corrosion around the edges of the opening for the inspection plates and a considerable amount of scum and algae growth. Bleach has

Joe Nieters of Dillon, Colorado, asks: “What are the advantages of a rigid boomvang? Many boats I’ve seen with them seem to also have topping lifts, and a lot of the rigid vangs also have a block-and-tackle control arrangement.” Win Fowler replies: The advantage of a rigid boomvang is that it supports the boom. Having a topping lift and a rigid
