The Gigrower magazine featured a huge feature section on rowing technique and articles on how to “make your gig go faster”.

We looked at Crew Selection, The Boat, Oars, The Rowing Stroke and The Cox.

If you have read these articles and would like to discuss any of the points raised, please leave a comment below. We’d love to hear from you.

    I am not sure it was in this section, but there was a bit about choosing heavier vs lighter rowers.

    If I recall correctly, the conclusions was that a 100kg rower needs to put out roughly 25% more power than an 80kg rower, being 25% heavier. There was some extra stuff about the boat sitting lower in the water with a heavier crew, but I think something more important was omitted: this calculation should’ve included the weight of the boat each rower is moving through the water.

    If we assume for simplicity’s sake that a gig weighs 600kg, then each rower has to move 100kg through the water (again a bit of an assumption, middle of the boat is likely moving more but lets keep it simple).

    In which case, a 100kg rower has to move 160kg (themself + share of the boat) while a 80kg rower has to move 140kg. Therefore the 100kg rower needs to put out only 14% (extra 20kg is 14.3% of the 140kg the lighter rower is moving) more power than the 80kg rower to have the same power to weight ratio.

    So the original was an over-estimate of the extra power required by a heavier rower.

    Happy to have my sums/assumptions checked.

    Dear David,

    Thank you for your comment.

    For this estimate we assumed the gig was race weight, around 275 kgs.

    Off course the heavier the boat the more this relationship is diluted, i.e. the heavier the boat the less the weight of the rower matters.
