I have a lot of respect for you, your company, and the type of anchor you sell. As I mentioned earlier, I use a fluke anchor as my primary anchor. That said please do not take offence at my questions. I use a 17lb. Danforth style anchor on a 4500lb 25' sailboat (I know it's overkill, but I like overkill). I paid $70 for it at a local boat dealer. Why does yours cost five times that? I am not trying to be a butt, is there that much difference in the type of material or design? They look very similar. Defender has your 15lb for $324.99, and Defender is usually the cheapest place for almost anything that has the word "marine" (which is code for really expensive) on it.
Thanks for your kind words, and you are not being a "butt" for your fair question.
The anchor we recommend for a 25' sailboat in normal wind and bottom conditions is the 4 lb. FX-7, which costs $109.99 at Defender.
Danforth makes 3 different anchor model versions: Standard, Deepset II, and High Tensile, which basically translates to good, better, best.
If you compare recommended anchors for specific boat sizes, you should find the Fortress to be in the ballpark price-wise with the Danforth Deepset II and High Tensile anchors.
I could not find a 17 lb model in their charts, and I suspect that you have a 16 lb Standard model, which sells for $79.99 at Defender.
The closest Fortress anchor in size to that 16 lb Standard model is the 10 lb FX-16, which sells for $212.99 at Defender.
While Danforth and Fortress share a similar anchor design (fluke type) and have similar dimensions, their differences are significant:
1. Danforth anchors are made from steel and are galvanized, while Fortress anchors are made from an aluminum alloy and are anodized, so the Fortress is obviously much lighter and it will not rust.
2. Danforth anchors are welded permanently together, while Fortress anchors are made from aluminum extrusions, so Fortress anchors can be disassembled for easy storage or for parts replacement.
3. Danforth anchors have a 32 degree shank / fluke angle only, while the Fortress has an adjustable 32° or 45° shank / fluke angle. The 45° angle will dramatically increase the anchor's holding power in soft mud, and it is an exclusive & patented feature with the Fortress.
4. Danforth anchors are dull-edged, while the Fortress anchors are precision-machined to be very sharp for faster and deeper soil penetration. Kind of like a dull knife compared to a razor.
This is absolutely one of the key reasons why a lighter Fortress aluminum anchor will out-perform a heavier Danforth steel anchor. The weight that is on top of the anchor from being deeply buried, rather than the weight of the anchor itself, is what will determine the anchor's holding power.
5. Danforth anchors have some form of a limited warranty, while Fortress anchors offer what I believe is the most painless warranty in the marine industry. It is called a Lifetime Parts Replacement Warranty, and we never require the customer to produce a sales receipt or to register the purchase with us, or even send back the damaged anchor parts.
If a customer damages an anchor part, no matter what the circumstance, we send them a new anchor part for free, they just pay S & H. Since the parts are light and we ship via the US Postal Service, this cost is usually nominal, and likely to be minimal.
I hope that this information has been helpful.
