Fish 0 Posted March 27, 2018 Share Posted March 27, 2018 About 3 cm wider than your arse? I am interested in the proper answer for this. What sort of rowboat are you referring to? yacht tender? I've seen a lot of boats that tend to have a ratio of about 3:1 length to beam, maybe a bit more tubby / beamy for dinghies (i.e. 2.5:1). If you want a fast rower, the narrower the better, improving the prismatic coefficient. For example a rowing single scull is often narrower than your arse (sliding seat and rower sitting on top, not in). Noting your comment of rowlocks at gunnels complicates things. The faster you want to go the longer oars needed, which then need the rowlocks further outboard to get the most efficient lever arm. For a standard clinker type dingy, I'm going to go with 1.5 m beam (assuming length is sufficiently long enough). Weren't you building a proper Wellsford sculler?

Black Panther 1,592 Posted March 27, 2018 Author Share Posted March 27, 2018 I gave the welsford joansa away for numerous bottles of mt gay. Once we bought BP I realised I no longer needed a garage project to console me for not having a real boat. I'm looking at a tender but to fit it on deck I would have to tweak the measurements from the plans. Add a bit of beam and length. But if I go wider my bum and arms stay the same.

Vorpal Blade 89 Posted March 27, 2018 Share Posted March 27, 2018 While your bum and arms stay the same you get better rowyness from longer oars, a way to achieve this is outriggers outside the gunwale for the rowlocks which mean you can have longer oars with slightly bigger blades and therefore more rowyness. Having spent the last 5 years (with 3 more to come) with the Westlake Boys Rowing squad has taught me lots about rowing, almost to the point where we were considering a single skiff with the associated outriggers, sliding seat and sweeps oars as a cruising addition to the VB - or a bigger outboard for the RIB.

waikiore 400 Posted March 27, 2018 Share Posted March 27, 2018 For a practical tender (like our nutshells) they are about 4' 6" wide with 6' oars on a 7'8" overall length, all tested by rowing around Browns Island and back to NZ ! Other designs are available... of course longer is better without increasing beam for rowing performance . The practicalities of fitting on deck and carrying them up the beach single handed force the compromise of short length on a dinghy that still has to - on occasion take a five man crew ashore dry.

Black Panther 1,592 Posted March 28, 2018 Author Share Posted March 28, 2018 Thanks wsikiore. That's what I wanted. The design is 8 ft but I can stretch it to 9 and still fit between the masts. But the beam would go out to just over 4 ft to accommodate dorades. Quote Link to post Share on other sites
Black Panther 1,592 Posted March 28, 2018 Author Share Posted March 28, 2018 I would have loved to take the Joansa but you'd need a small ship. Quote Link to post Share on other sites
Deep Purple 512 Posted March 28, 2018 Share Posted March 28, 2018 60’ long, you should be able to fit this stunner. I want to build one when I’m retired http://www.newfound.com/liz.htm Quote Link to post Share on other sites

Deep Purple 512 Posted March 28, 2018 Share Posted March 28, 2018 I wonder how long he had to practice that? Quote Link to post Share on other sites
