The OE 36 baseline rig yields a lower sail-area-to-displacement ratio than contemporary cruising designs, which led to a specification that increases mast height by about 6 feet, lowers the collo d'oca by ~18 inches and lengthens the boom by ~18 inches to recover usable mainsail area and improve light-air performance.
At a glance: measurable changes and why they matter
Increasing the testata while reducing the gooseneck raises the effective P measurement (mainsail luff) and expands sail area without radically altering deck layout. For a family cruiser like Spica (OE 36), the modest changes preserve handling while delivering notable gains in upwind and light-wind speed—important both for private cruising and for charter or tour operators who must maintain schedules and guest comfort.
Key specification changes
| Elemento | Originale | Upgraded | Scopo |
|---|---|---|---|
| Altezza dell'albero maestro | Baseline OE 36 | +6 ft | Increase sail area, light-air performance |
| Gooseneck | Higher clearance | -18 in | Easier mainsail flaking, cockpit ergonomics |
| Boom length | Standard | +18 in | Balance mainsail area and sheeting geometry |
| Forestay attachment | Colophon | ~2 ft below masthead (17/18ths fractional) | Manage headsail size, avoid runners |
Practical rigging details that affect operation
Beyond gross dimensions, the specification focused on operational ergonomics and long-term reliability. Important items included:
- Halyard exit placement raised to allow a six-foot crew member to apply leverage without short-arming.
- Rope clutches at each halyard exit with proper spacing to keep all mast lines at the mast base (no aft leads).
- Four sheaves in each end of the boom (three for reefs, one for the outhaul) and an aft-facing winch base beneath the gooseneck for reefing tension.
- Low-friction mast track (ballbearing-free Antal style) proven on long-distance boats such as Isbjørn.
- Redundant halyards: two mainsail halyard sheaves with one doubling as topping lift/spare.
Standing rigging and factory choices
For longevity and strength, through-bolted exterior mast tangs were specified in preference to lighter T-bolts. Mast fittings were pre-planned for both a solent stay and an inner forestay to preserve the option of carrying multiple headsail configurations for oceangoing passages. These factory-fit choices reduce retrofit work and potential leaks, and they help keep the decks clear—factors that matter for guest safety on chartered sails and excursions.
Deck handling and downwind ops
A mast-mounted spinnaker pole track sized to allow the pole to stow vertically on the mast was included. On a 36-footer the weight penalty is small while the operational benefit—faster poling, less deck clutter—is significant for day charters or weekend yacht parties where crew resources and guest comfort matter.
Systems integration and small details
Wiring runs and dedicated fittings for OGM LED nav lights from Weems & Plath were included in the spec to avoid frustrating revisions at install. Sheave-box exits were planned for spinnaker, jib, pole topper, staysail and solent halyards to ensure redundancy—because when cruising or running tours you can never have too many halyards.
Specifying these elements at the factory simplifies installation and improves long-term maintainability—vital for owner-operators, charter fleets, and anyone considering a family cruising refit with tourism uses in mind.
Checklist for a cruising-oriented rig refit
- Decide target sail area vs handling: conservative fractional rigs reduce the need for runners.
- Position halyards for ergonomics and safety.
- Prioritize through-bolted fittings where strength is required.
- Plan wiring and nav-light mounts during fabrication, not afterward.
- Include halyard redundancy and accessible clutches for single- or short-handed sailing.
