Compact Tools That Work in Boat Tight Spots
Alexandra
Many interior deck mouldings and coamings on production boats leave screw heads and nuts recessed behind channels often under 32mm of clearance, making routine maintenance a logistics problem for parts, tools and hands alike; compact drivers such as the NaRo confined space ratchet driver and short extension bars routinely solve access issues without removing bulkheads or disrupting stowage layouts.
Field-tested compact tools for screws
When trim panels or deck fittings are installed before hull assembly, crews frequently encounter recessed screw heads. Practical, space-conscious tools reduce time spent disassembling structures for access.
Key screw solutions
- NaRo confined space ratchet driver — holds standard bits and operates in channels as narrow as 32mm; ideal for overhead trim and transducer brackets.
- Socket driver with bit adapter — a 1/4in socket set adaptor (Stanley and similar) provides extra torque where the NaRo lacks leverage.
- Stubby screwdrivers — compact and inexpensive; a four-piece stubby set covers common heads and fits tight recesses.
- Thumb ratchet — useful for rapid rotation when limited swing exists; good for long, repeated tightening.
- Offset (cranked) screwdriver — trades speed for clearance, working slowly to shift stubborn or rusted screws.
Approaches to awkward nuts and bolts
Nuts recessed in coamings or hidden near tanks are some of the most time-consuming fixings. The right combination of low-profile tools and extension elements gets jobs done without cutting panels.

| Tool | Typical clearance | Best use | Notes |
|---|---|---|---|
| Thumb ratchet | 25–40mm | Initial take-up on a nut; narrow channels | Limited final torque; good for positioning |
| Swivel head ratchet | 30–50mm | Angled tightening inside coamings | Allows alignment then swivel for leverage |
| Long extension bar on ratchet | Varies by bar length | Recessed bolts deep inside lockers | Extra clearance for full swing |
| Box spanner | Small recesses where socket walls bind | Recessed nuts with thin access | Often sold in sets with short leverage bars |
| Crow’s foot spanners | Side access required | Seacock and plumbing fittings near bulkheads | Can be used with long ratchet for reach |
Useful nut-starting aids
- Finger spanners (HexHold) — pressed steel cups that fit over a finger to hold a nut steady while locating it on a bolt; excellent for blind starts but not for high torque.
- Duct tape — inexpensive method to temporarily attach a nut to a spanner for threading when visibility is zero.
- Adhesive blobs (mastic, Blu Tack, grease) — sticky compounds can temporarily hold a nut in place while a partner turns the bolt from the accessible side.
Drilling, cutting and rotary options for confined spaces
Accessing a drilling position is often constrained by lockers, bunks and overhead mouldings. Compact drilling systems and flexible drives extend capability without major disassembly.
- 90° drill (DeWalt and equivalents) — reduces effective tool length to roughly a quarter of a standard drill, allowing holesaw and bit use in shallow cavities.
- Dremel with flexible drive — ideal for cutting and sanding inside small lockers; the flexible shaft concentrates work at the head while keeping the motor assembly remote.
- Flexible drive tools — inexpensive and compact; less precise but very maneuverable where bulk is the limiting factor.
- Reciprocating saw — with bimetal blades, this tool removes unwanted trim or tabbing inside tight voids rapidly; ensure blade selection matches material.
- Milescraft Orbiter — angle-adaptable drilling jig for complex angles; useful for precise through-deck holes but requires extra space for the jig itself.
The essential tools to keep on your boat
A compact toolkit for cruising or charter use should include a set of stubby and combination spanners, a thumb ratchet, a swivel-head ratchet, a 90° drill or adapter, a Dremel with flexible drive, a selection of short extension bars, and adhesive aids for nut-starting. Keep items organized in a small kit bag to reduce loss risks — the same stowage discipline used in rigging stores and galley provisioning applies.
Practical tips from sea trials
Testing different tools across typical awkward fixings shows that a layered approach works best: use low-profile drivers and finger spanners to start threads, then switch to swivel-head ratchets or extension bars for final torque. For cutting or drilling, favour flexible-drive solutions when the access envelope is narrow and reserve bulkier jigs for planned refits. Ben Meakins’ demonstrations underline that patience and the right compact tool usually prevent the need for invasive dismantling.
