Re: Fabric weight for genoa

These are good points, Rich, but except on Volvo Ocean racers packing Cuben Fiber Code Zeros, most kick-about sailors are willing to sacrifice ten degrees of pointing for pure boat speed. A bit of...

Re: Fabric weight for genoa

How large is the #1 you have now? I agree w/ Markwesti that nylon drifters are the cat's meow, especially in light-air venues like the Chessie. Very easy to set and douse, store in a tiny bag, and...

Re: Halyard and roller furler

We're facing the same issues with our Albin Ballad. Both forward masthead sheaves are spoken for, and we may be adding a double crane for spinnaker Code 0 halyard blocks. How to get the spi...

Re: BS1088 bulkhead installation inquiries

Re: BS1088 bulkhead installation inquiries

Here's the major bulkhead tabbed in. It is the original African mahogany (khaya) ply and hasn't been epoxy painted yet; we still have some overhead epoxy work to do.

Re: BS1088 bulkhead installation inquiries

Assume you plan to glass these bulkheads to the hull using epoxy resin? If so, you are gonna get epoxy all over the wood anyhow -- tabbing is a messy affair. So I'd advise rolling a coat of epoxy...

Re: Rudder Failures

Yes. Impulse energy is a big deal, and the more static the system, the higher the likelihood of breaking limits being exceeded. You can try to design for worst-case dynamic loading scenarios, but I...

Re: Help the "new generation" pick a cruising boat

Even quite a large boat is smaller than a typical efficiency apartment. If someone snores, everyone's gonna know about it. If someone's using the head or makin' whoopie in the forepeak, everyone's...

Re: San Juan 23

Try Stephen Jensen in Seattle:

He took over the San Juan parts inventory after Gene Adams managed it for decades. I suspect you are needing gudgeons for your...

Re: How to build a holding tank

John: we faced the same issue when searching for water tanks for our Albin Ballad. The boat came with only ~14g of water tankage, and we are planning to sail where fresh water is hard to obtain. And...

Re: Anemometer for a wind voyeur....

Most home weather stations -- esp. wireless -- offer fairly low resolution. For instance, our Zephyr Instruments (a re-labeled older design) only polls every 45 seconds or minute. Seen fractally,...

Re: Advice For Good Boat To Learn On

The O'Day might be a fine choice, but budget in at least a new (or good/used) mainsail for it. The number of tears & their location (leech) indicate badly damaged fabric. Probably a combination of...

Re: Advice For Good Boat To Learn On

Nancy, another common boat in your size range, price range, and region is the famous Shark 24 (http://www.shark24.org/). It's a quirky little boat, likes a blow, might need some light air help. But...

Re: Advice For Good Boat To Learn On

Re: 1989 Hunter 40 - A million questions.

Best. Gear. Ever.

Honestly. Our nylon genoa/drifter/Code0 was the best addition we made to the SJ21 -- added a full knot to our average speed to and from Catalina, got the boat moving in early...

Re: What size winches?

Single speed #7s or #8s should do just fine if your leads are fair; if they aren't, bigger winches won't make life much better, as chafe & hardware strain will still be there. For even quite large...

Re: Alternative to Solar

Here's an inherent difficulty of tidal generators: you know how a tide chart is basically a sine wave, showing min/max peaks every six hours? There's another sinusoidal graph about 90 degrees out of...

Re: Alternative to Solar

Re: Alternative to Solar

Re: Alternative to Solar

Re: Resawing 1 x 4 mahogany

Hi, David. Bandsaws are great for resawing, since they remove less stock than a typical TS blade, are relatively safe (no kickback), and can get by with less HP than you need driving a 10" circular...
