1987 Frers 30. Great racer/cruiser. Very potent in light air. Many new parts and upgrades during 2022-2024 refit: New Competition Composites rudder and new bearing. New chainplates and stemhead fitting. New standing rigging. New Flex-a-fold 2 blade prop, shaft, cutlas bearing, stuffing box, and coupler. New Sail Technologies radial main with Tides track. New fuel tank. New battery charger. New motor mounts and stainless exhaust mixer. Winches dissasembled/cleaned and greased. New Spinlock rope clutches. New LED cabin and running lights.New boom cover New Standard VHF. New portlights, portholes, and one new hatch. New mainsheet and vang blocks. Last bottom job October 2024 Pettit Vivid. Keel bolt nuts removed, inspected, and torqued by local boat yard. Deck was stripped of all hardware for repaint. A few sections were recored. Painted with Epifanes two part. Interior varnish has been stripped and 8 coats have been applied. Old jib. The bugs have been worked out of the boat and we had a reliable racing season 2024-2025. Reason for selling: Dream boat came on the market and could not pass her up. This is a great boat and all major lifting/systems has been done.
Equipment: Yanmar 2gm20 (smokes at start, but runs well). Hood genoa furler Main Jib
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)
