491012-1 — Fixed, 1 piece
Look for a single-piece aluminum shaft measuring 48 inches with the larger replacement-hook design.
Identify Sea-Dog Boat Hooks: 491012–491036 Lengths, Tips and Sections
When an aluminum boat hook is missing its label, the number of pole sections and the stored length are often more useful than the colour of the handle. Sea-Dog's six 491-series models include fixed and telescoping styles. Use these exact manufacturer dimensions to identify a matching pole, hook tip or mooring-cover accessory.
Recognize your boat-hook configuration
One continuous pole
491012-1 and 491013-1 are fixed 48- and 72-inch designs. Both use the larger 491052-1 replacement-hook style.
Two-section telescoping
491021-1 closes to 24 inches and extends to 36; 491024-1 runs 48 to 96 inches. Both use the smaller 491051-1 hook.
Three-section telescoping
491034-1 is 36–96 inches, while 491036-1 is 56–144 inches. Both have a listed 1-1/4-inch closed-pole diameter.
Cover support accessory
491110-1 is a UV-resistant nylon crown that threads onto Sea-Dog boat hooks. Its tie-down webbing straps are separate.
Sea-Dog 491-series identification chart
Sea-Dog's A and B specifications correspond to closed and extended lengths in the chart; for one-piece models the fixed length is the same.
| MPN | Style | Stored length | Extended length | Closed pole diameter | Replacement hook MPN |
|---|---|---|---|---|---|
| 491012-1 | Fixed, 1 piece | 48 in | 48 in | 1-1/8 in | 491052-1 (large) |
| 491013-1 | Fixed, 1 piece | 72 in | 72 in | 1-1/8 in | 491052-1 (large) |
| 491021-1 | Telescoping, 2 pieces | 24 in | 36 in | 1-1/8 in | 491051-1 (small) |
| 491024-1 | Telescoping, 2 pieces | 48 in | 96 in | 1-1/8 in | 491051-1 (small) |
| 491034-1 | Telescoping, 3 pieces | 36 in | 96 in | 1-1/4 in | 491051-1 (small) |
| 491036-1 | Telescoping, 3 pieces | 56 in | 144 in | 1-1/4 in | 491051-1 (small) |
Small versus large replacement hooks
Replacement hooks: Sea-Dog specifies 491052-1 (large) for fixed models 491012-1 and 491013-1. The 491051-1 (small) is specified for telescoping models 491021-1, 491024-1, 491034-1 and 491036-1. Do not substitute one replacement family for the other.
The orange end cap is separately identified by Sea-Dog as 491050-1. The poles feature a removable orange tip and a universal/Acme threaded accessory connection. The optional 491110-1 cover-support crown works with Sea-Dog boat hooks; webbing straps are not included with the crown.
Checks when identifying an older part
- Count the sections and measure the pole fully collapsed. Do not assume two poles with the same extended length are the same model.
- Identify the threaded accessory connection and replacement-hook family: 491052-1 for the fixed 491012/491013; 491051-1 for telescoping 491021–491036.
- Measure the stored diameter as well as length before choosing a storage clip. The separate 491145-1 clip is rated for poles up to 3/4 inch and should not be assumed to secure these thicker poles.
- Check the actual product condition and included accessories in the listing before purchasing a replacement.
Match the manufacturer number to a product
The linked products are identified individually by Sea-Dog manufacturer numbers. Open each listing to check its stated condition and current availability.
491013-1 — Fixed, 1 piece
This is the six-foot fixed-length version, not a telescoping pole. It uses the larger replacement-hook size.
491021-1 — Telescoping, 2 pieces
Identify the short two-section pole: Sea-Dog lists 24 inches closed and 36 inches extended.
491024-1 — Telescoping, 2 pieces
The two-piece 48–96-inch pole has the smaller replaceable hook, despite its extended length.
491034-1 — Telescoping, 3 pieces
Check for three sections, a 36-inch closed length and a 1-1/4-inch listed closed-pole diameter.
491036-1 — Telescoping, 3 pieces
A three-piece design extending to 12 feet; distinguish it from the shorter 491034-1.
491110-1 — Mooring-cover support crown
Nylon accessory for a compatible boat-hook threaded tip. Check that straps are supplied separately.
