Quote......As soon as you feel the boats rear dig in At this point you use the same term as the Royal family do in such circumstances "MY ARSE!" If you have a passenger with you getting them to sit foward of amidships will help the craft stay level and actualy the boat will go a shade faster two up than with just one person sitting at the rear. Mad Mike PS we haven't even discussed the various differences between the boats performance in fresh water as opposed to salt, then of course there is atmospheric pressure to take into account and ambient temperature let alone air humidity because as everyone knows a higher humidity will increase poweroutputbyafactorof1+tothepowerod4.73recuringdevidedbythelastprimenumberxPiAghhhhhhhhhhhhhhhhhhhhhh

If that is so, QED. Mad Mike

Ah in that case I don't think the 15hp will have quite enough power to put it on the plane, therefore the rules regarding displacement boat speed being governed by the W/L length apply. Except that he might get about 8knts out of it before the 'hump' became too big for the boat to climb over and plane. A 25 hp engine will make the world of a difference to the top speed. Mad Mike

Have a look at the picture attchd. Most of them have a threaded top that the aerial unscrews from. It's not a good idea to cut the aerial lead and re join but I guess that a co-axial cable join as used in TV applications could be used ecept that the final mechanical joint needs to be well encased in self amalgamating rubber tape. Mad Mike

It may have been a mistake of the writer is the point I was making. I have never come across a boat with a stated speed in anything but Knots although I imagine there will be someone to tell me that in Ulan Bator that's what they do and also they measure in Yak power. Mad Mike

If indeed the 'k' is a kilometer and not a kurnot This busness of hulls being rated to X knots is a purely arbitrary thing placed on a hull by a manufacturer or again an arbitrary speed limit sugested by some insurance underwriter at which the insurance premiums rise. Most often these stated figures are the whim of a retailer whishing to impress a potential buyer with an 'informative' specification. In this country there is no public authority that tests the sea worthyness, durability, useability, or safety of small craft (more's the pity). The questions of engine output on boats is greatly misunderstood. for example quoted HP. Well is that HP at the crank? The gear box? The propeller? Which is worst an under-proped engine reving at a max rev rating of 5000rpm and going nowhere? Or an over prop'ed engine strugling to get up to 1500rpm and straining it's little ball cocks off. To get the correct answer as to what engine HP/useable rev range/economy/efficiency is required one must also answer the question as to what craft it is to used on and the likely use that the craft will undertake. Mad Mike

QUICK get the Kryptonite Mad Mike

Not a lot!

If it is a displacement hull then the max speed can not possibly be 18kph (or what ever that is in Knots. There is a quite strict equasion of calculating the maximum hull speed of a displacement boat. Which is Sq root of WL X 1.5 (to 1.7 if one is talking about a very clean narrow and long hull) equals the hull speed in Knots. For most boats the Sq root of the waterline length X 1.5 = hull speed. If your boat had a waterline length of 16ft the squ root is 4. Times 1.5 = 6knts and most importantly it will always be in the region of 6knts no matter what power is applied. All that more HP will do is shift more water from under the stearn which created a hole that the hull can not climb out of. So....... If you engine has a nice economical run speed of say 3300 revs (which is probably about right) but can not attain those rev's (by ear will do) then the engine is 'over' prop'ed. The pitch is to coarse and the dia too large. If on the other hand (very unlikely) it rev's it's little head off and the boat hardly accelerates and eventualy only goes along at a slow walk, then it is 'under' prop-ed. Propeler's can be re-pitched to a max' of 1" either way. Mad Mike

Blimey! With the greatest of respect do you feel that all of the information you have asked for is of any real use? Max engine rev's Mmm probably 5500, ideal eco cruising 3500, with a suitable flatish hull but entierly different with a full bodied displacement hull. But nothing is going to change or matter with all the knowledge you ask for. As the performance of the boats hull and the engines required torque at whatever hull displacement speed/water condition/ engine rev's/propeller pitch x diameter is what it will be. Let your ear be the guide, if the engine is over stretched you will hear it, a rev counter on a 15hp/16ft boat is realy un-necessary, as the hull shape and displacement has far far more affect on things than your engine. By that I mean that a 15 hp engine will gain the hulls maximum dispacement speed as will a 4hp engine too. One could go on pouring power into the 15hp's output but the boat will not go any faster, it will just sit down at the back and raise it's nose. To be of any real help in answering What is the max. rev range for the above engine? 2)What revs is it doing at its max design speed of around 18 kph? One would have to know what was the hull type it was coupled too. Mad Mike

There are many manufacturers of epoxy putty. It is usualy a two part formula with the two pastes packed together but only becoming active when mixed by kneading together. This mix when set, has the property of a fileable metal, push into the holes leaving enough protruding each side to ensure a permanent fixture and mould whilst still pliable into shallow domes. When set (2 to 6 hrs) sand to a smooth finish and spray paint with the appropriate colour. Mad Mike Ps If you can't source the putty give me a shout and I will give you enough for the job.

Got out fairly early and went round to Whithouse grounds off Swanage. Plenty of makies on a drift when we were nearly there, but no fish coming to the mackerel baits drifted over the bottom. So we went to an area that has always produced for me when the tide is running fast and anchored. Sure enough bites from LSD's and Thornbacks came quite quickly and we were catching a steady flow of them for about an hour (Thornies up to 12lb). We had noticed a steadily darkening sky to the SW and could hear the distant boom of thunder. We discussed our options and decided that we would stick it out for a bit longer, however I took a compass bearing on Swanage Pier just incase. And thank goodness I did! Within five minutes the darkness was on us together with a strongly gusting SW wind force 5 gusting 6 together with horizontal lashing rain. We had just enough ime to get the anchor up before the worst hit us. Picking up on the compass bearing we headed gently in sliding down the rapidly formed waves and burying the bow from time to time. A complete white out of driven rain and mist prevented our seeing anything much beyond 30ft but eventualy we made it into the calm of Swanage bay and picked up a bouy to wait the storm out. We were both soaked to the skin and the deck had about 2" of rain and sea water swilling over it . It was at this point that I realised the bilge pump had packed up. We sorted ourselves out a bit and decided to call it a day so when the little tantrum of a storm had passed us by we set off home. As we approached Old Harry we saw the Life Boat attending to a large (35ft) yacht that had been driven hard up on to the reef and listening in to Ch16 we could hear many emergancy calls from both the Solent area and Portland CG's all too far away from us for us to be able to respond to. But it did make us think that all the belt and braces safety equipment we have aboard certainly gave us a comfortable feeling when in the worst of it, and that learning how to handle the boat in poor contitions together with knowing how to take and use compass bearings made what for some people were disasters into a bit of an adrenalin rush for us having the confidence that we knew what we were doing. I think the club helped enourmously in insisting on high safety standard for all club boats and also in the flow of knowledge that adds to the experiance of all of us.

Nikid Wimmin? Mad Mike

She's probably off for a new career in the Indian Navy... Yes and under remote control too.................. They use a call center in Mumbai to con her! Mad Mike

The problem you describe sounds like the return signal to the transducer is not being recieved as the boat has traveled too far forward from the 'send' point to read it. This was a common problem of the very early depth sounders. The freezing of the depth signal will be the readouts default of the last known depth. You slow down and then the return signal does have time to get back to be 'heard' by receiving bit of the transducer and the diplay starts up again. If the unit is a modern one then something is very wrong and I don't think it will be transducer position. The signal sent out by the transducer is a wide angle beam not a tight one, therefore unless you are going super fast (50knts+) or in extremely deep water (600ft+) the boat should normaly be within the returns footprint. Now as I type this the thought occurs to me ....... Do you have the flat underneath part of the transducer angled forward a lot (more than 5 deg) ? If so that could cause the problem. WHere is the boat ? I could come and have a look ? Mad Mike

winged washer A 'tab' washer Often universal, take what remains of your old one to Propeller Developments at Cobbs (round the back to the left of the entrance) I am certain they will find a match for you. Mad Mike

Quote..... 100 m. would do for me. If you wany to split it, or share with someone else ?? Would someone give me an idea of how much the 100 meters going spare would cost me please? Mad Mike

Sorry Mike it will have to be

Well I thought it was funny Mad Mike Any road up we're out Saturday so expect high winds, hail, rain and a meteor shower this weekend!

The end of an era for naval legend Sir Galahad was the first ship to sail into Umm Qasr during the Iraq war Her name will always be associated with one of the darkest days in recent British military and naval history. When RFA Sir Galahad was bombed during the Falklands War in 1982, 48 lives - a fifth of all British fatalities - were lost. Many who died were Welsh Guards. The badly damaged ship was sunk and in 1986 a new Sir Galahad was launched. On Thursday, she made her last journey under the Royal Fleet Auxiliary's flag, as she sailed from Marchwood to Portsmouth to be decommissioned. The ship means a lot to the RFA and her departure is inevitably tinged with sadness Capt Rob Dorey Captain Rob Dorey said: "This is a significant time for many who have been associated with RFA Sir Galahad over the years. "The current ship has seen service throughout the world and made a valued contribution to many operations, including the supply of humanitarian relief to people in desperate need." Sir Galahad was the first ship to sail into the Iraqi port of Umm Qasr during the war in 2003, bringing humanitarian aid to the country. But the name conjures strong emotion in many who took part in the Falkland's conflict. Capt Dorey said: "Many associations originating from the Falklands campaign still hold the name of Sir Galahad dear to their hearts. "This was evident during the recent farewell visit to South Wales, where a number of veterans from the Galahad association and the Welsh Guards were hosted onboard. Nearly 50 people died during the attack in Bluff Cove in 1982 "The ship means a lot to the RFA and her departure is inevitably tinged with sadness." It was on the 8 June, 1982, that Sir Galahad and her sister ship RFA Sir Tristram came under attack in Bluff Cove at the height of the British operation to recover the islands from their Argentine invaders. Nearly 50 soldiers and sailors died, but among the survivors was Welsh Guardsman Simon Weston, who suffered horrific burns in the attack. Sir Galahad caught fire almost immediately and the badly damaged ship was towed out to sea and sunk as a war grave. Horrific scene The captain of Sir Galahad, Phil Roberts, later gave his account of the day. "It all happened very suddenly. The planes came out of nowhere and they bombed us and the ship was set on fire very rapidly," Capt Roberts said. "We had to abandon ship fairly quickly. The scene was horrific." The original ship was built in 1966 as a "landing ship logistical". Its role was to support amphibious operations by landing troops, tanks, vehicles and other heavy equipment in port or on any suitable beach. Capt Dorey said the current RFA Sir Galahad would be replaced by a new, larger "Bay Class" ship called RFA Cardigan Bay.

BBC (Southern) News Man held over boatyard violence Police officers wrestled a man to the ground as he brandished a screwdriver and threatened to harm himself. They were called to Brighton Marina on Thursday morning after reports a man on board a boat had turned violent and was running amok with a screwdriver. When officers tried to calm him he threw missiles at them and threatened to harm himself. The incident was brought to an end when he was overpowered and then checked by paramedics before being put in custody.

Bilge pump 1750 gph 12v.

WAIT A MIN' ! Same idea but reversed so the boat is stretched back against the rubber as in a sling. Let go the ratchet holding everything in tension and .......... THWUNK!!!! A boat launching catapult for Baiter Mad Mike

Your scaring the newbies again Oh! Sorry Mad Mike

Copper grease is used to ensure that componants like the bolts that hold brake disks, cylinder head retaining bolts etc do not sieze in their respective threads due to the drying out of lubricant due to heat. Some people like to use it in connection with O/B because its got the word 'copper' in it. Total waste of time IMO Mad Mike
