One of the best moments out of the shop is when customers asks us to deliver sib or rib with engine having already passed it's break in period as most of them likes to run hard inmediately after a 3 minute warm up time is completed.
This time tested a very eye catching new Sea Rider heavy duty 310 rib with Tohatsu 18 HP short shaft. This 60 Kg rib is intended mostly for tender use, the hull is a a square bathtub with 2 small keels to sides and a larger keel up front. Although very stable had my doubts about it’s water performance because of the hull lenght which is only 2.50 mtr long and tubes barely touches water.
This small rib is rated for a 15 HP, but were sure a 18 will have the extra power to overcome fast the huge hull drag with superb and neat plane. After cruising on flat calm no wind waters with well trimmed engine and 2 passengers evenly distributed on tubes for 3 long hours varying engine rpm each 15 minutes and bored at such a slow speed decied it was time to open the throttle to ?.
Oh boy, to our surprise, the nose skyrocketed for 3-4 eternal seconds to jump on plane happily, throttle back to ? and maintained an excellent planning speed. Once you overcome the initial fear to skyrocketing for seconds and once the beast has been completely tamed will end enjoying it very much. As the saying says “what goes up must come down”. A down issue with small ribs is that at close turns you end losing planing speed and rib tends to sit down, if overpowering, must adjust swivel bracket load a bit and tiller steer very gently or will have unpredictable serios issues...
Have discovered long ago since buying my first Tohatsu that if this brand engine is not seated at a correct transom height you won’t get the full max HP power the engine delivers, besides having horrible water splashes of all kinds and excessive tail drag at back transom.
On this 310 rib, transom/keel distance was factory modified to be 41.0 cm, water flow is passing at just 2 mm under small upper plate with rib & cav plate riding parallel to water level. In order to count with Tohatsu engines and achieve inmaculate water performance, all our sib/rib transoms have been factory height modified.
After final break in period and with no throtle limitation at all on our way back to port raced against a Sea Eagle 420 with a Yam 30 HP. Not a real competitor against the smaller Beauty & Beast mostly because sib as usual was under inflated, deck was flooded, and that cheapo plastic pannel deck rocked like if it were at a music concert, bad music for the owner, a hard and expensive way to learn not to buy crappy sibs that look state of the art as seen at online web pages...
