Anchor Selection for the GW 330 Express (yr. 2006), I am unable to upload the images referenced in my summary. PM me if you would like to see any.
We have had our 2006 GW 330 Express for 6 months. We had not been satisfied with the Delta 22lb Fast Set anchor. We live in Southeast Florida and anchor in sand primarily and the plow dragged too much for us to feel comfortable spending the night at anchor somewhere and didn't set quickly. We began the research for a new anchor. Our research of various independent holding power tests gave us a shortlist with Rocna, Manson Boss, and Manson Supreme. The Manson and Rocna are considered new generation anchors, and are rated at super high holding power per our research. For good measure, we also included a 35 lb. Delta plow and an original 33 lb. Bruce claw made in Belgium in our comparison.
The question would be which one will fit our bow pulpit and anchor roller?
We bought all the anchors from three different West Marine stores to test them on our boat. Here is a photo of all the anchors, Left to Right. Rocna 15(35lb), Rocna 10 (22lb), Manson Boss 25lb, Manson Boss 15lb, Manson Supreme 25lb, Manson Supreme 15lb, Delta 22lb, Delta 35lb. The entire group of anchors compared (excluding the 33lb Bruce claw)
Our final choice was the Rocna 10, (22lb). We also changed the chain length to 36ft vs the standard 15ft that came with the boat. Below is a summary of each of the anchors that fit on the boat without any modifications.
The four that fit, L to R, Delta 22, Delta 35, Manson Supreme 15, Rocna 10.
Summary
1. Rocna 10 (22lb), we chose the Rocna 10. It fits excellent in the pulpit and on top of the roller. At 22lbs it is the proper sized anchor for the size of boat, and it is a new generation anchor with higher tested holding power than the Delta plow and Bruce claw. The roll bar will put the anchor in the proper position if dropped on its back. We like how the scoop of the anchor makes contact with the blades of the bow pulpit for stabilization. The shank also has clearance inside the pulpit box without touching. We used it this weekend in Lake Boca and it set quickly and held strong while backing down on it in reverse. We will have better test soon when we travel to the Bahamas and the Keys to anchor overnight.
2. Rocna 15 (35lb), does not fit well. The scoop of the anchor does not rest on the blades of the pulpit for stability and the anchor's role bar rubs on the gel coat fiberglass part of the front of the pulpit.
3. Manson Boss 15lb, does not fit well. The scoop of the anchor does not rest on the blades of the pulpit for stability. It does not rub on the pulpit box , but instead holds on the roller based on a curved section of the shank. It is also not the proper sized anchor for the size of boat.
4. Manson Boss 25lb, does not fit. The scoop of the anchor does not rest on the blades of the pulpit for stability and the anchor's shank wedges inside the pulpit box between the roller and the forward section of the box. We didn't feel comfortable with this fit. Due to the wedging the anchor would not drop by itself using the windless. The Anchor stuck in the roller area.
5. Delta 22, fits excellent in pulpit. It is the recommended anchor from Grady White. Most GW 33 Express owners selected this anchor. No images since this is the standard anchor the GW 330 Express uses.
6. Delta 35 fits well in pulpit, and is the MAX weight recommended by GW at 35lbs. Would be an upgrade over the 22lb Delta.
7. Manson Supreme 15lb, fits but is not the proper size anchor for the size of boat according to the Manson website. You can see the blades of the pulpit barely make contact with the scoop of the anchor.
8. Manson Supreme 25lb, does not fit, the roll bar hits under the bow pulpit. No images but fits similar to the Rocna 15.
9. Bruce 33, Genuine from Belgium - does not fit, the shank is too tall and wedges itself against the top of the anchor pulpit box. We had this anchor on hand, so decided to try it.
