Planing through an anchorage is standard in the Caribbean
and as most lunatics don't get that far from home, I don't think it's making things less safe or comfortable. What I do not like is dinghies that only just don't go into plane: these are the ones that pull a huge wake, rocking all boats in the anchorage etc. Also, planing saves fuel
big time and gives drier rides. Bigger diameter tubes help too but only if you plane (even drier ride). Big tubes without planing is still a wet ride.
When comparing weights you have to realize that 4-stroke is much bigger and much heavier. Also, in many countries they will laugh at it when you need it repaired. They don't even have the parts
, sometimes they never saw it before. In the range of dinghy
motors it's purely 2-stroke out here. Come to the cruising grounds with what you have and buy a new 2-stroke here. Much cheaper too. The Yamaha Enduro series rule
(professional use line) but also weigh more. I think 8-10' dinghies with 15hp outboard
are the most common combination in the Caribbean
I was charmed by the small (like 4 hp) 4-strokes and considered one for spare motor
until I heard of the problems. Cleaning
carburetors was a daily job for many when the gas isn't as clean as "back home". 2-strokes deal with any quality gas.
About speed: I measured it with handheld GPS
. An Avon
RIB-310 with 15hp Mercury
and my big 250 pound body does 22 knots in calm water
, 16 knots with two people. A Caribe C12 with 25hp Enduro does 25 knots with 1-3 persons, 18 knots with 4 persons. I fitted those "wings" on the anti-cavitation plate for better control. The C12 will go uphill with a 1' chop like a bat out of hell in relative comfort and without getting wet. You still stay dry in a 2' chop if you manage to stay in the dinghy
... we tack upwind in those conditions. We took both dinghies mentioned above out into the big waves (8' or so) and could do every course on plane without trouble. We actually catch fish
that way when we feel like having it for dinner.
