1987 ODay 35
The ODay 35 is a fine sailing sloop with a comfortable interior and built-in swim step. Interlude is a clean, lightly used New England boat that has just undergone a top-to-bottom refit to bring her into Bristol condition. Everything has been replaced and improved this boats is immaculate and shiny, needs nothing and is ready to sail away. Always buy the boat in the best condition this is that boat.
Equipment: Refit was completed in 2023 and includes: Bottom blasted, new barrier coat and ablative paint. New Rudder from Foss Foam Keel was removed, faired, all keel bolts replaced with SS 316, rebedded, better than new All new Groco through-hulls New propeller shaft (Aquamet 22), cutlass bearing, coupler, PSS dripless shaft seal New Pro-Furl C320 roller furler All new standing rigging New chainplates All new running rigging Sail control lines brought aft, all new mast blocks, deck organizers and rope clutches Mast all rewired, all new LED lights, all new sheaves Boom, all new sheaves and blocks New lifelines 6 new Lewmar opening ports Deck hardware removed, repotted and re-bedded, new cleats, new deck fills, re-chromed winches Deck is dry with no core problems M-25 Universal diesel, low hours, super clean, runs like a top, all recommended updates, new motor mounts, new glow plugs, Oberdorfer raw water pump, all new hoses, wiring and instrument panel New fuel tank, Racor fuel filter, fuel pump and fuel hoses Two new Duracell Golf Cart batteries (house), New Group 31 battery (reserve), all new battery cables, batteries moved to interior from engine room (345 amp hours) Solar panel, MPPT charge control, Automatic Charge Relay to keep batteries topped-off Pro-Mariner battery charger, power cord Lots of new wiring, positive and negative buss bars, everything is properly fused Interior is in excellent condition, light use, all teak refinished, custom cabinetry, new galley sink and faucet, propane oven JVC audio/video head unit (200 watts), 4 speakers and 32 flat screen TV New Raritan PHII head, hoses and holding tank All new bilge pump and cockpit drain hoses Clean crisp sails, jib has 3 light seasons, main has 6 light seasons Garmin 741XL chartplotter, Data Marine depth sounder, Icom 422 VHF New Manson Supreme anchor, chain and rode, Danforth back-up Simrad WP-32 auto-pilot Dodger, sunbrella cockpit cushions Edsen pedestal table with drink tray Coast Guard safety equipment, Life Sling, dock lines, fenders, spares And many more improvements
The theoretical maximum speed that a displacement hull can move efficiently through the water is determined by it's waterline length and displacement. It may be unable to reach this speed if the boat is underpowered or heavily loaded, though it may exceed this speed given enough power. Read more.
Classic hull speed formula:
Hull Speed = 1.34 x √LWL
A more accurate formula devised by Dave Gerr in The Propeller Handbook replaces the Speed/Length ratio constant of 1.34 with a calculation based on the Displacement/Length ratio.
Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio.311
Hull Speed = Max Speed/Length ratio x √LWL
A measure of the power of the sails relative to the weight of the boat. The higher the number, the higher the performance, but the harder the boat will be to handle. This ratio is a "non-dimensional" value that facilitates comparisons between boats of different types and sizes. Read more.
SA/D = SA ÷ (D ÷ 64)2/3
A measure of the stability of a boat's hull that suggests how well a monohull will stand up to its sails. The ballast displacement ratio indicates how much of the weight of a boat is placed for maximum stability against capsizing and is an indicator of stiffness and resistance to capsize.
Ballast / Displacement * 100
A measure of the weight of the boat relative to it's length at the waterline. The higher a boat’s D/L ratio, the more easily it will carry a load and the more comfortable its motion will be. The lower a boat's ratio is, the less power it takes to drive the boat to its nominal hull speed or beyond. Read more.
D/L = (D ÷ 2240) ÷ (0.01 x LWL)³
This ratio assess how quickly and abruptly a boat’s hull reacts to waves in a significant seaway, these being the elements of a boat’s motion most likely to cause seasickness. Read more.
Comfort ratio = D ÷ (.65 x (.7 LWL + .3 LOA) x Beam1.33)
This formula attempts to indicate whether a given boat might be too wide and light to readily right itself after being overturned in extreme conditions. Read more.
CSV = Beam ÷ ³√(D / 64)
Similar to O’DAY 34 but with swim ladder on extended stern which accounts for extra length.
Shoal draft: 4.25’/1.29m
See O’DAY 34.
