Date Posted:

Patrick Laine is a solo sailor who shares his adventures on his YouTube channel.

He initially sailed single-handed on a Bavaria 40 sailboat in the Atlantic1. He is based in La Rochelle, France1. In early 2021, he sold the Bavaria and bought a Bongo 28 foot made in France in 2009which is much smaller and faster than the Bavaria, but also much less comfortable1.

After a circuit of the Atlantic during the Spring/Summer of 2022, he sold the Bongo and bought a new RM 890+

Review of Bongo 8,70

Basic specs..

Unknown keel type

The boat can enter even shallow marinas as the draft is just about 1.43 - 1.53 meter (4.69 - 4.99 ft) dependent on the load. See immersion rate below.

Sailing characteristics

This section covers widely used rules of thumb to describe the sailing characteristics. Please note that even though the calculations are correct, the interpretation of the results might not be valid for extreme boats.

The immersion rate is defined as the weight required to sink the boat a certain level. The immersion rate for Bongo 8,70 is about 200 kg/cm, alternatively 1120 lbs/inch. Meaning: if you load 200 kg cargo on the boat then it will sink 1 cm. Alternatively, if you load 1120 lbs cargo on the boat it will sink 1 inch.

Sailing statistics

This section is statistical comparison with similar boats of the same category. The basis of the following statistical computations is our unique database with more than 26,000 different boat types and 350,000 data points.

What is L/B (Length Beam Ratio)?

Maintenance

If you need to renew parts of your running rig and is not quite sure of the dimensions, you may find the estimates computed below useful.

Bongo 15 is a 15 ′ 1 ″ / 4.6 m monohull sailboat designed by Paul Cronin and built by Abbott Boats Inc. starting in 2003.

Rig and Sails

Auxilary power, accomodations, calculations.

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

Max Speed/Length ratio = 8.26 ÷ Displacement/Length ratio .311 Hull Speed = Max Speed/Length ratio x √LWL

Sail Area / Displacement Ratio

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

  • SA : Sail area in square feet, derived by adding the mainsail area to 100% of the foretriangle area (the lateral area above the deck between the mast and the forestay).
  • D : Displacement in pounds.

Ballast / Displacement Ratio

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

Displacement / Length Ratio

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

  • D: Displacement of the boat in pounds.
  • LWL: Waterline length in feet

Comfort Ratio

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 Beam 1.33 )

  • D: Displacement of the boat in pounds
  • LOA: Length overall in feet
  • Beam: Width of boat at the widest point in feet

Capsize Screening Formula

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)

Asym.Spin. area: 147 sf’. It is reported that the molds for the BONGO 15 were destroyed in a fire so it’s unlikely that more than the initial 43 will be built.
